It's not about the technology changing.
But people do add improvments to python packages over time, and release
newer/better packages.

Yes, and I apologize if I seemed curt.  You happened to touch on a pet
peeve of mine.

In the Windows world, people complain and moan about Microsoft releasing
continual updates of their software with obscure and relatively trivial
additional features, so much so that I suspect many of the developers
within the sound of my voice are still using Office 2003 (now 7 years
old) and Visual C++ 6.0 (now an incredible 11 years old).

But in the open source world, if a product goes for 12 months without a
significant update, people start asking, "Is this product dead?  Should
I use something else?"  There does come a point in the life of every
piece of software where the product is DONE, when it does what it was
supposed to do.  After that point, additional updates are just pointless
eye candy.

Now in the case of pyparallel, that's not fair of me.  It is clear there
are additional useful features that could have been added, like EPP and
ECP support.  So, you were right to ask, and I'm just monologuing.

Message-ID: <166165.58186.qm@web56402.mail.re3.yahoo.com>

After doing a fresh install of Python 2.6.3, I ran
pywin32-214.win32-py2.6.exe, downloaded from
http://sourceforge.net/projects/pywin32/

At the end of the install was a dialog box stating that
"Postinstall script finished" but with an error message:

Traceback (most recent call last):

? File "<string>", line 149, in LoadSystemModule
ImportError: DLL load failed: This application has failed to start
because the application configuration is incorrect. Reinstalling the
application may fix this problem.

Googling uncovered a report of an identical error message at:

?http://mail.python.org/pipermail/python-win32/2009-July/009336.html

with pywin32 build 213 and which stated that this problem had been
fixed with build 214.

In desperation, I uninstalled Python 2.6.3 and installed Python 2.6.2,
but still received the same error message shown above when installing
pywin32 on top of Python 2.6.2.

I'm running Windows XP SP2 and did a brand new install of Python
2.6.2/2.6.3 -- with the "Just for me" dialog box checked -- in
directory E:\tools\Python26 (using python-2.6.3.msi downloaded
from http://www.python.org/).

Please help.

Thanks,

Aha, I just reinstalled 2.6.2 without the "Just for me" checkbox and
this time pywin32 installed successfully with the following message:

Copied pythoncom26.dll to C:\WINDOWS\system32\pythoncom26.dll

The pywin32 extensions were successfully installed.

BTW, I've been installing Python with the "Just for me" checked
because I don't like polluting my C:\Windows\system32 directory
with third party DLLs.

In particular, I need to set up a Python installation for all users
on a network drive, so don't want any files installed on the local
drive. Any tips on setting up a shared Windows Python install on a
network drive for all users would be appreciated.

Thanks,

I have 2.6.2 running with pywin32-214. On XP SP2 as well.  I installed for 
all users, however.  Have you tried that?

Subject: [python-win32] How to use COM when there isn't a type library or
	IDL file
Message-ID: <51ae820a0910050858u3a87582dhf7bea1700e9110f7@mail.gmail.com>

I am trying to use Microsoft's RealTimeStylus COM classes from Python.
I want to access the RealTimeStylus object, and I want to create
Python objects that support the IStylusAsyncPlugin. The difficulty is
that there is no type library specifying the relevant interfaces, nor
is there an IDL file. All I can find are Microsoft's C/C++ header
files in the Windows 7 SDK. My registry has an entry for the CLSID for
RealTimeStylus, but it doesn't have entries for the interfaces
IRealTimeStylus or IStylusAsyncPlugin.

I know very little about COM, but it seems to me that I should be able
to read through the C/C++ header files for the relevant COM
interfaces, and write a Python equivalent. (I don't think I can use
makepy because there is no type library, and I don't think I can use
the Dispatch approach because (a) RealTimeStylus does not implement
IDispatch and (b) that's no use anyway for server COM.)

I know very little about IDL and about COM, and I have no idea how to
go about translating the C/C++ header files into Python. I would be
very grateful if anyone could give me some tips, or pointers about
what I should read to do this, or correct misconceptions in what I
wrote above.

The stuff below is excerpted from rtscom.h, and it looks like the
interface IRealTimeStylus which I would like to use in Python.

Subject: [python-win32] Python and ASP - failure on 2nd and subsequent page
	loads
Message-ID: <32AA3A83235A25458AB5387177B883F8110C528AEE@MAIL.ith.local>

I would be grateful for any advice about a problem which is preventing me from using Python for my current project.

I am hoping to use Python 2.6 on the server side with Microsoft ASP [not ASP.NET; version details below]. The behavior I see is:

1. Load very simple page [text below] into browser [Firefox or IE, versions below]. Everything displays, fine.
2. Exit browser, restart it, and reload the same page; or open a second tab and load the same page.
3. In either case, page fails to load, with error:
Python ActiveX Scripting Engine, ASP 0211 (0x80020009)
A built-in ASP object has been referenced, which is no longer valid.
If I edit the page in any way, or just 'touch' it, and refresh the browser, the page will load correctly the first time, and then fail again as described.

The page I am using has no actual Python scripting, just the LANGUAGE directive and then the html and body tags with a little plain text.  Of course, things don't get any better if I put in some actual Python.

I found a five-year-old newsgroup posting with what seemed to be a similar (but not identical) problem. This thread said that the problem went away if server-side debugging was turned off. I have it turned off, no effect. I also tried adding some Response object settings to disallow cacheing, but these did not have any effect.

Version Info:

Python: 2.6.2
PyWin: pywin32-214 (I ran the client\pyscript.py and server\axsite.py scripts for setup)
Client OS: Windows XP Pro SP2
Browsers: Firefox 3.0.14, IE 8.0.6 [identical bug]
Server: IIS 5.1

Note, I also tried using Python 3.1 with corresponding pywin, but I could not get that to work with ASP at all; just got server 500 errors. I'd prefer to use 2.6 anyway since I am fairly new to Python.

I would be very grateful for any expert pointers on this, since if I can't solve it I will probably have to go use PHP, Javascript, or something else. Thank you!

I started getting this error message yesterday. I can use system restore to eliminate it but it returns when ever I try to follow any links. Do you have a permanent fix?

Subject: [python-win32] SSPI/NTLM authentication via XMLRPC
Message-ID: <6894a6470910081611t24da4be8r77370a4fe1061595@mail.gmail.com>

Hi,
I was wondering if this would be possible:

At the minute i have a login xmlrpc call that takes a username/password as
an argument. simple enough, authenticates off the windows domain via
LogonUser(pywin32), the user then gets a cookie for the session(to execute
further xmlrpc calls).

I was wondering if it would be possible to achieve SSO using SSPI/NTLM via
XMLRPC?

I see an example in win32/Demos/sspi/socket_server.py, im not sure if
something similar could be used via XMLRPC.


Thanks,

David

Off the top of my head I can't see why not if you control both the 
client and the server and don't mind making them do an auth dance to set 
things up - you probably want to check out the simple_auth.py sample for 
some idea of how it could be implemented.

Cheers,

Mark

Subject: [python-win32] How to use COM when there isn't a type library
 or IDL file
In-Reply-To: <51ae820a0910050858u3a87582dhf7bea1700e9110f7@mail.gmail.com>

This is very tricky to do in pure-python.  Other interfaces with this 
issue (eg, the shell interfaces) tend to use custom c++ code (often 
generated by the 'makegw' package then heavily edited) to implement a 
win32com 'sub-module'.  The best alternative for you may be to 
investigate how comtypes might help...

Cheers,

It's not clear how this relates to Python - if it does you will need to 
provide much more information.

Message-ID: <36dec4ff0910090728k37cd9954rabe430514f550cbc@mail.gmail.com>

Hi everyone...

I've been searching high and low looking for any sort of decent
reference for the win32api in python and I can't find anything that is
useful.

The only real explanation I've found is the msdn site, but as I'm not
a C programmer, translating the various calls to python and guessing
what the python functions are called is probably an exercise in
futility at best.

So I wanted to start off by asking if any of you can point me to some
site or document that lists the various python calls to the win32api.

What I'm trying to do ultimately, is improve our testing scripts,
which are all python.  They are cross-platform and geared to run on
both windows and Linux systems in test.  The linux side is fairly
trivial, as I am pretty intimate with getting  what I want from a
Linux system.  However, getting that info, programmatically in Windows
is new ground for me and because I want this stuff to be as light as
possible, and portable, I don't want to rely on a bunch of extra
Windows tools to get the info.

The win32api has the calls I need, I just need help or a reference to
get them over to python.

So what I'm trying to do for now, is fairly simple.  I just want to be
able to make a couple calls and get system info like the number of
processor packages, the number of processor cores, processor flags (if
possible), free mem, total mem, OS version and a few other tidbits of
system information.

Any ideas that will help me get a clue?

Jeff

There isn't much, in spite of a few attempts (my own included)
to get something going. There's never enough time...


Ultimately, the win32api calls *are* wrapping the MSDN calls
almost directly so you just have to dive in, but ...

Here at least I can help. Try using WMI which eats this kind of
thing for breakfast[*]. Start here:

  http://timgolden.me.uk/python/wmi.html

taking in this:

  http://timgolden.me.uk/python/wmi-tutorial.html

and this:

  http://timgolden.me.uk/python/wmi_cookbook.html

and feel free to get back with specifics.

Awesome!  Thanks a lot.  I'll dig into that after lunch.  I finally
stumbled on the ActiveState info on win32api with a ref for all the
calls, and I'll have to do a little more digging.  I found out finally
how to pull SYSTEM_INFO (turns out it IS farily trivial) but now I
have other things to figure out (which is nice, as it actually gives
me something to do while I'm waiting on the next project to start).

I can pull most of what I need now after finding the ActiveState
reference, but specifically, I'm having trouble with:

Number of logical processors (counting cores with and without
HyperThreading enabled in BIOS)
Number of processor packages
Total system RAM
Available RAM

I think I can figure out the RAM, but right now it's the processor
counting and info that's dogging me.

Anyway, like I said, I'll dig into the WMI stuff in a bit after a nice
break from the lab and this nasty chair.

Thanks a lot for the pointers!

Thanks,
Sorry for not doing my homework but what does the "auth dance" entail, how
many backwards and forwards would there be, seeing as every bit of data
would have to be encapsulated via xmlrpc, would that potentially mean many
calls?

Well that's simply a copy of the CHM which is provided with
the pywin32 installation. I host another copy over here:

  http://timgolden.me.uk/pywin32-docs/contents.html

for private entertainment. It's fairly searchable using Google, eg:

http://www.google.co.uk/search?q=site%3Atimgolden.me.uk%2Fpywin32-docs+EnumProcesses

and has a bit of breadcrumbness about it to help you out. But,
as I say, it's merely an online copy of the .chm which is itself
eminently searchable.

Although I'm the author of the Python wmi module, WMI itself
covers such a huge area that I have absolutely no pretence
at comprehensive knowledge. Faced with queries such as yours,
I'd normally just stick, eg, "available ram wmi" into Google
and go from there. There's lots of info out there aimed at
C or vbs developers; translating it into Python's usually
not too hard.

Subject: [python-win32] PythonWin Grep modifications
Message-ID: <62701E6B0F1948DABDD7950A17DBD1A1@efcore>

I've made some modifications to PythonWin's Grep functionality. At first I 
just wanted to add highlighting for the regex matches, but I guess I got 
carried away. :b  I'll eventually submit it to SourceForge, so that Mark may 
include it in the official release if he wants. In the meantime, here's the 
current version: http://www.mediafire.com/file/mmjntzmjwmm/sgrepmdi.py

To test it, replace "pythonwin\pywin\framework\sgrepmdi.py". If anyone's got 
any more suggestions, fire away.

Here's a list of the changes so far:
    Functionality:
    - added match highlighting
    - replaced editboxes with combos to store MRU items
    - added keyboard handling:
      - Enter opens match (same as double-click)
      - AppMenu opens context menu (same as right-click)
    - added support for registry root key shorthands ('HKLM', 'HKCU', etc.)
    - added folder selection via common dlg
    - changed settings INI location to %AppData%;
      originally it defaulted to %WinDir% which wouldn't allow writing in 
Vista
    - made richedit control readonly
    Code & UI:
    - added a couple of comments, docstrings, and constants
    - added SearchOptions, PathSet, IniFile
    - replaced list-based dir/file/mask traversal with a generator
    - added msgboxes for Open/Save errors
    - added specific types to except clauses
    - replaced glob() with os.listdir() (glob() chokes on dirnames with 
square brackets)
    - replaced 'MS Sans Serif' dlg font with 'MS Shell Dlg'
    - tweaked dlg layouts and added a couple of icons
    BUGS:
    - setting text format is off by 1 sometimes (e.g. XP vs. Vista); maybe 
richedit EOL related
    - saved results file has junk at the end and uses \n as EOL
    - dirs and files are not generated in sorted order
    - context menu should be shown over the richedit cursor (not the mouse) 
when opened with the keyboard
    - right-clicking should move the caret before showing the context menu
    TODO:
    - tweak "More" dialog and rename to "Favorites"
    - keyboard: make Delete remove whole match line
    - add options for fonts, colors, regex (e.g. highlight all matches, not 
just first)
    - test on Python 3

comtypes: If neither a type library nor an idl file is available,
then you can still create the interface definition manually.
You can probably, given some experience, define the interface
by looking at the header file.  I started this for the first few
methods of the IRealTimeStylus interface:

"""
# module realtimestylus.py
from ctypes import *
from ctypes.wintypes import *
from comtypes import IUnknown
from comtypes import GUID
from comtypes import COMMETHOD

class IRealTimeStylus(IUnknown):
    _iid_ = GUID('{A8BB5D22-3144-4A7B-93CD-F34A16BE513A}')

IRealTimeStylus._methods_ = [
    COMMETHOD(['propget'], HRESULT, 'Enabled',
              ( ['retval', 'out'], POINTER(c_int), 'pfEnable' )),
    COMMETHOD(['propput'], HRESULT, 'Enabled',
              ( ['in'], c_int, 'pfEnable' )),

    COMMETHOD(['propget'], HRESULT, 'HWND',
              ( ['retval', 'out'], POINTER(c_int), 'phwnd' )),
    COMMETHOD(['propput'], HRESULT, 'HWND',
              ( ['in'], c_int, 'phwnd' )),

    COMMETHOD(['propget'], HRESULT, 'WindowInputRectangle',
              ( ['retval', 'out'], POINTER(RECT), 'prcWndInputRect' )),
    COMMETHOD(['propput'], HRESULT, 'WindowInputRectangle',
              ( ['in'], c_int, 'prcWndInputRect' )),

    # here are quite some methods missing...
]
"""

Then you can create such an object, QI for the interface, and try to use it.
I had to look up the CLSID for the RealTimeStylus class in the registry.

>>> p = CreateObject("{E26B366D-F998-43CE-836F-CB6D904432B0}")
>>> print p
<POINTER(IUnknown) ptr=0x12e0848 at 1bfa3a0>
>>> p.QueryInterface(IRealTimeStylus)
<POINTER(IRealTimeStylus) ptr=0x12e0848 at 189e120>
>>> s = p.QueryInterface(IRealTimeStylus)
>>> s.Enabled
0
>>> s.Enabled = 1
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "comtypes\__init__.py", line 278, in __setattr__
    value)
_ctypes.COMError: (-2144862203, 'The clear disable flag is set and all clear operations now require physical access.', (None, None, None, 0, None))

However, I would only recommend this approach to an experienced

Ok... that all helped a lot.  I've been playing around with memory a
bit, and cache, and I'll poke at that some more later.  Today I've
been looking into processors.

So WMI provides Win32_Processor and from what I've read, there exists
one instance of Win32_Processor for each processor on a SMP machine.

So for starters, I assume then that if I had one such machine, I could
count all the cores simply by doing something like:

for p in c.Win32_Processor :
    procCount = procCount + 1

which makes sense.

Now that I look at it, I seem to be able to pull information based on
each core, and I can count cores.  But what about counting processor
sockets or packages?  For example,

Lets say, I do that simple loop and get a return of 16.

How do I differentiate between 16 cores, or 8 cores with
HyperThreading turned on?

Admittedly, that's more an educational curiosity.  The systems I'll be
using all this on are readily accessible, and we'll know ahead of time
that System A has 2 4-core processors and that we turned HT off in
BIOS, so we should only see 8 logical processors when we test.  Any
delta from that will fail the test.

So like I said, I was just curious if there is any built in way via
WMI or whatever to differentiate without having to go and manually
create a class based on the Windows API (because I'm not good enough
to do that kind of work).

Either way, thanks for the help so far, the WMI wrapper is pretty
cool.  I've never written system level code before, beyond
instrumenting some device drivers and services to see why they break,
so this has been pretty fun so far as a learning experience.

Cheers
Jeff

Ummm. Not quite.

c.Win32_Processor is a class-ish thing which you have to call to
pull back the *list* of instances. Which you can then just
count. So something like this:

n_processors = len (c.Win32_Processor ())

I can't at this moment remember how the c.Win32_Processor interacts
with physical processors, multicore processors and hyperthreading.
It's probably documented somewhere, and a little experimentation
should give you answers quite easily. That's the great thing with
Python: you just fire up the interpreter and get the answer!

This is definitely the place to look for this kind of information:

http://msdn.microsoft.com/en-us/library/aa394373%28VS.85%29.aspx

unfortunately, some of the useful information like NumberOfCores
and NumberOfLogicalProcessors seems to be available only on the
very latest releases. Might be an issue for you?

Glad it's been useful. I'm just releasing a new version of the
Python module which includes a little web server whichi lets you
browse around the classes to a limited extent. If you're interested,
let me know.

And it does indeed work.  We're using the latest 2.6, and so far
everything has worked well. NumberOfCores and
NumberOfLogicalProcessors does just what I hoped they would do, so now
I have a small bit of n00b code:

print "Getting processor information now...\n"
numProcs = len(c.Win32_Processor ())
print "Number of Processor Packages found: " + str(numProcs)
for p in c.Win32_Processor ():
  print "Number of processor cores: " + str(p.NumberOfCores)
  print "Number of Logical processors: " + str(p.NumberOfLogicalProcessors)
  if p.NumberOfCores != p.NumberOfLogicalProcessors :
      print "HyperThreading seems to be enabled."

and that's enough to start.  For now, I just need to be able to
actually pull accurate information. Later on, I'll write a class for
all this so the other scripts can reference them easily... but this
way, I can check packages, cores and logicals, and whether or not
HyperThreading is enabled; though my logic should be:

if p.NumberOfLogicalProcessors == (p.NumberOfCores * 2)

instead of just a !=.  BUT, either way should work on any multi-core
system I can think of.  Know of any instance where that wouldn't work
accurately?

THANKS!  Once again, you're wisdom blows my mind ;-) and your link-fu.
That was one of the things I had hoped to find as I was searching.
That was exactly the kind of information I needed to get things going.
 Just a simple example and a brief explanation of what each item is,
without diving into C or C++ and trying to translate that later.

Sure... it'd be neat to play with.  Like I've said before, this is
going to be actually useful, but I'm doing it out of boredom and as a
learning experience more than I am doing it to benefit work or
anything like that.  They don't pay me enough to really want to work
for their benefit ;-)

I have run into another issue though with the various Memory classes...

I thought I was counting DIMMs, but I think I was just counting
sockets.  I thought I was totalling the amount of Physical memory, but
instead I was getting the max supported for each socket...

I've tried CIM_OperatingSystem (which works and gives me the free
physical memory).

I've also tried Win32_*Memory* classes as well as CIM_Memory, and none
of those have successfully given me the actual physical memory.

for each class, NumberOfBlocks either returns nothing, or returns the
wrong information.

I've got 4 256MB DIMMs in my desktop, which is what I'm using to work
on this right now.  Hopefully, they'll find me something with more
DIMMs and higher capacity to play with to make sure this will work on
systems other than my desktop...

But for now, all I'm ending up with is the max capacity for the system
(4GB) not the total installed (1GB)...

I can't seem to find the right Memory related class to get either the
amount present per dimm or the total physical amount present.

I'm still looking into that... and that'll probably be my day.
thankfully, they don't really have much at all for me to officially do
right now, so I've got plenty of time to mess around with this and see
what different things do.

Cheers
Jeff

I suspect you're coming from a C background? Or something
similar. Python's a very versatile language and tries to
help you avoid boilerplate. So you can do things like this:

<code>
import wmi

c = wmi.WMI ()
numProcs = len (c.Win32_Processor ())
print "Number ...:", numProcs
# or
print "Number ...: %s" % numProcs
</code>

and likewise for your other print statement. (Watch out:
print has become a function in Python 3.x). The percent-s
thing works just like sprintf in C only with a Python touch:
you can use a more restrictive %d %2.3f etc. but if you put
%s, Python calls your object's __str__ method which will usually
generate what you expect to see.

Of course, I have done that once or twice before ;)

I'll put a release notice out in the next day or two and let you
know where you can get hold of it.

[... snip rather specific Memory stuff ...]

I'm afraid I've no particular insight here. I'm sure I can Google

Yeah... similar, I guess.  C++ to some degree, VB, Basic, a smattering
of perl, Java, and so on...  I can read C for the most part (even some
of the nasty stuff at the OS and hardware level) but I couldn't really
write C if my life depended on it.

To be honest, I started working in Perl about 9 years ago, and got
about half way through learning it when I discovered Python, and how
much easier Python is to write as well as read (especially when
reading someone else's code).  So I started learning python then.
Then I got laid off a few months later, and haven't really done
anything with it in ages.  So I still remember just enough Python to
be dangerous, and I'm trying to re-learn it as I go along...

Yeah... there's a lot I need to pick up again... and that's probably
the hardest part.  I have no idea where to even start.  Which is why
I'm doing this little exercise.  It'll get me some class writing,
importing, and doing some other stuff, but I'll end up missing some of
the most basic stuff, like output formatting and such...

Though I was interested in finding the functions to output to stdout
and stderr directly, which will be nice too...

Heh... honstly, outside of some nice long BASH scripts, this is the
first chance in years that I've had to actually write real code.  I
was a "software engineer" for 6 years, and I very rarely ever
engineered any software.  Most of what I wrote were shell scripts,
though some were rather complex and did some neat things.  That's
where I picked up the little bit of C I have, as I had to sometimes
instrument drivers and user-space applications to find out why a
particular test was failing, but that was limited use stuff.

I have a very long history with the general theory of programming and
writing code, but what I lack is current experience, and most
importantly, the vocabulary.  Which is why I'm asking so many basic
questions that I really could eventually find on my own.

I know WHAT I want to do with this program, I just don't know how to
tell Python just yet, though I'm pretty close at least to a proof of
concept.  Just like I know WHAT I want to search the Google for, but I
don't know exactly what words to search on, and in that last case, it
was really so simple that it never even occurred to me.

My second big failing... I sometimes overthink things. :-)

My next Python project (which I'll probably start working on later
this week as I get bored) is going to be a web CGI to search multiple
craigslist sites and display links to matching hits.  I know that's
been done to death, but it's something I thought of long before the
various aggregating sites started popping up, and it looks like it
would be fun.  Besides, it gives me a definite goal and a definite
product that will get me back into some web programming too...
something else I haven't done in ages.

By the way, I also figured out my own issues with finding memory.
CIM_OperatingSystem includes a TotalVisibleMemorySize attribute that
is what I was looking for.  I kept looking at things that had
PhysicalMemory in their names and I missed that one until I read a
little deeper into another WMI option...  That one gives the total
physical memory available to the OS, which is the total Physical minus
any shared memory... so on this machine, my 1024MB ends up being
1022MB... which is close enough for my purposes.

Cheers
Jeff

I'm curious what other users use for automating Windows & widgets with
Python (on Windows platforms that is).
By automating- I mean clicking buttons and activating check boxes, menus,
maximizing/minimizing Windows, sending keystrokes, etc.

>From what I've seen packages/frameworks like this are pretty scarce for
Python.
PyWinAuto was the only package that looked worthwhile using, but the
documentation drove me crazy.

I've opted for AutoIt3 which is a superb automation package, is mostly
C-like, is open source, very popular, actively supported and extremely
full-featured.
I'd rather do it through Python if possible. AutoIt3 has COM support but
only a measly subset is supported via COM.
(I try to stay as far away from COM as possible, though even it it means I
can use Python.I've had too many COM servers crash before a call returned,
leaving the client hung)

Subject: [python-win32] Passing Nothing into COM method
Message-ID: <0665012E4232B3438D417A337610837B30D9A2@NANAMAILBACK3.nanamail.co.il>

I am writing a COM addin, and attempting to trap the ItemAdded/ItemRemoved event in the following object:
Application.VBE.Events.ReferencesEvents
which is retrieved by passing Nothing as a paramter:
Application.VBE.Events.ReferencesEvents(Nothing)

Tim Golden wrote in the following post (http://mail.python.org/pipermail/python-win32/2009-February/008826.html) that pythoncom.Empty can be used for Nothing. However, when trying this:

try:
    self.comRefevents=self.app.VBE.Events.ReferencesEvents(pythoncom.Empty)
except pythoncom.com_error, (hr, msg, exc, arg):
    print "The call failed with code %d: %s" % (hr, msg)
        if exc is None:
            print "There is no extended error information"
        else:
            wcode, source, text, helpFile, helpId, scode = exc
            print "The source of the error is", source
            print "The error message is", text
            print "More info can be found in %s (id=%d)" % (helpFile, helpId)

I get back the following (the same as if I had passed no arguments at all):

The call failed with code -2147352561: Parameter not optional.
There is no extended error information

Eric Lippert states in his blog (http://blogs.msdn.com/ericlippert/archive/2004/07/14/183241.aspx):
> A common alternative to passing a missing argument is to pass Nothing, Null, or Empty in VBScript,

It would seem that VB's Nothing and Empty are two different things.

If I try passing pythoncom.VT_DISPATCH, then I get the following traceback:

Hi Everybody,

I have 2 imports:

import pythoncom
from win32com.client import Dispatch

if I run it on my Python 2.6 Console, it works nicely. However, when I go to
Eclipse IDE, open a project, open a main.py file, and try run, it gives the
error:

import pythoncom
ImportError: No module named pythoncom

All other imports are working ok on Eclipse IDE -- e.g. import MySQLdb.

Any suggestion about what is missing?

All comments and suggestion are welcome.

Two things to check, python version (sys.version), and sys.path.   Add
prints for the two of them at the beginning of your script, and try the
script in both environments.  If there are any differences, figure out how
to reconfigure Eclipse to match what you've got at the console.

-- hope this can help and save time for others too

Here is what did and works:
* copy the file mfc71.dll on windows\system32
* copy the same also on directories
* copy the same to your directories Python26\DLLs and
Python26\lib\site-packages\win32
* go to preferences : pydev : interpreter python : remove all the
interpreter you have there. apply, ok.
then add python 2.6 again, apply, ok.

It will do the trick.......|:0), ThreaderSlash

Sorry for the delay.  The problem seems to be caused by a silly bug in 
the axscript implementation.

To fix the issue locally:

* open 'win32comext/axscript/client/framework.py'

* search for ResetNamesItems - you should find the function def at line 747.

* Replace the implementation of that function with the one below:

	def ResetNamedItems(self):
		# Due to the way we work, we re-create persistent ones.
		existing = self.subItems
		self.subItems = {}
		for name, item in existing.iteritems():
			item.Close()
			if item.flags & axscript.SCRIPTITEM_ISPERSISTENT:
				self.AddNamedItem(item.name, item.flags)

Note that sadly this file uses tabs for indentation, so make sure you 
get that correct.  Also unwrap any long lines which my mailer wrapped.

* Restart IIS.

After that I can successfully reload the Python ASP samples (and before 
that I too saw the symptoms you described).  I will check that into cvs 
so the next pywin32 version will have that fixed.

Cheers,

Mark

Passing Application.VBE.Events.ReferencesEvents(None) works (at least at this point).
However, when I try to bind to an event class, I get the error below.
Any assistance, debugging suggestions, would be greatly appreciated.
Thanks.

See the docstring for DispatchWithEvents - you probably want something 
closer to:

acc = DispatchWithEvents('Access.Application', RefEvents)
acc.Visible = True
win32com.PumpMessages() # sit here doing nothing but waiting for events...

Cheers,

Subject: [python-win32] Seemingly identical COM-calls fail in Python client
	but work in other client
Message-ID: <af58ee3f0910160646x385f889el78c9b0487ea50a6c@mail.gmail.com>

Hi!

I am trying to control the electromagnetic simulator CST Microwave Studio
from Python using COM automation, and I am experiencing trouble:

>From Matlab, I use the following calls:

cst = actxserver('CSTStudio.Application');               % Launch the
simulator application
mws = invoke(cst, 'OpenFile', 'my_project_file.cst'); % Open simulation
project file
a_s11 = invoke(mws, 'Result1D', 'a1(1)1(1)');  % Acces a previously
caculated result
N = invoke(a_s11, 'GetN');  % Get number of samples in result

Everything works fine from Matlab. When I use Python,l however, I find
myself in trouble when I attempt to create the "Result1D" object:

import win32com.client
cst = win32com.client.Dispatch("CSTStudio.Application")
mws = cst.OpenFile("my_project_file.cst")
# So far, everything is fine, the program starts, and the file opens, but
from here on...
a_s11 = mws.Result1D("a1(1)1(1)")

... I get the following traceback:
[C:AbstractMeas/src]|54> mycst.mws.Result1D("a1(1)1(1)")
-----------------------------------------------------------------------
com_error                                 Traceback (most recent call last)

C:\Users\emicgeb\workspace\AbstractMeas\src\<ipython console> in <module>()

C:\Python26\lib\site-packages\win32com\client\dynamic.pyc in Result1D(self,
*args)

com_error: (-2147417851, 'The server threw an exception.', None, None)


I have no idea what has gone wrong. Any suggestions how I could find out
what's going on?

I'm using dynamic dispatch (can't find anything that seems suitable to run
through makepy.py... :-( ? ). Python 2.6.3, pywin32-214.

I would appreciate any help or suggestions.

Michael

hi mark. thanks so much for looking into the matter. unfortunately, i'm the
odd person out here because this fix hasn't solved my problem. i implemented
the fix and restarted the server, to no avail. thinking i had screwed up my
system with previous tries, i did this:

- uninstalled python and pywin32 from my computer.
- downloaded and reinstalled python 2.6.3 from python.org.
- downloaded and installed pywin32 from sourceforge.
- made the change to framework.py using a text editor that could identify
tabs vs spaces.
- ran python pyscript.py (even did the old --unregister trick first).
- rebooted the computer entirely.

it came back up and my program looks like this:

<%@LANGUAGE=Python%>
<HTML>
<head></head>
<body>
<h1>Python Test</h1>


</body>
</html>

when i run it, it works the first time. then i hit refresh and i get this:

Python ActiveX Scripting Engine error '80020009'

Traceback (most recent call last): File "<Script Block >", line 1, in
<module> Response.WriteBlock(0) File "<COMObject Response>", line 2, in
WriteBlock COM Error: Object has no dispatch interface available.

?, line 0
then when i hit refresh again, and every subsequent time, i get this:

Python ActiveX Scripting Engine error '80020009'

Traceback (most recent call last): File "<Script Block >", line 1, in
<module> Response.WriteBlock(0) File "<COMObject Response>", line 2, in
WriteBlock COM Error: OLE error 0x80020101

?, line 0
i verified that framework.py is the new one. something that seems odd to me
is that the framework.pyc and framework.pyo files both have modification
times from BEFORE when i changed framework.py, so my instinct is they didn't
recompile properly. however i don't fully understand if/how they're supposed
to, so i may be off.

any thoughts? thanks mark for your help and i'm sorry to come back with
another question.

That certainly is suspect.  Did you install it in "\Program Files" by 
chance?  It almost looks as though the python dir can't be written to so 
the "virtualization" has been enacted.  Certainly you should see the 
.pyc and .pyo files dated later than a .py file you modified.

Cheers,

Mark

Thanks for taking the time to answer, and for pywin. I've been using pywin with COM for some time, and am only now (when something doesn't "just work") starting to appreciate its internal complexities.

I get back the following error:
>>> com_error: (-2147467262, 'No such interface supported', None, None)
I have a very sketchy understanding of COM's internals, but if the IDispatch interface was supported, wouldn't Dispatch() be using that?
Also, is there any way of getting the interfaces which an object does support?

Thanks again,
Zev

Sorry, I did mislead you.  After reading this in more detail your 
initial code looked correct.

Try something like:

disp = 
acc.VBE.Events.ReferencesEvents(None).QueryInterface(pythoncom.IID_IDispatch)
refsEvents=DispatchWithEvents(disp,RefEvents)

To ensure we are passing an IDispatch rather than an IUnknown to 
DispatchWithEvents.

HTH,

Mark

Hrm - IDispatch not being supported makes things a little tricker.

It would be interesting to know if:

ti = 
acc.VBE.Events.ReferencesEvents(None).QueryInterface(pythoncom.IID_ITypeInfo)

works?  If so, we can possibly convince DispatchWithEvents to work with 
the object.  If not, then you may find comtypes is the way to go...

Cheers,

IDispatch is not supported.
I have an issue using comtypes, which I have already resolved using pywin32. I need to pass Nothing (or the equivalent) into
acc.VBE.Events.ReferencesEvents
Under pywin32, I pass None, and that works.
What is the equivalent of Nothing in comtypes?

Often just a Null pointer of the correct type, e.g. 

   NullPtr = POINTER(Iwhatever)()

If a VARIANT is required, one of VARIANT.empty, VARIANT.null or 
VARIANT.missing.

I am coming from VBA, and my understanding of COM internals is very weak.

2 questions:
1) What do I replace IWhatever with, and how do I find that out? (The 
argument is supposed to be of type VBProject)
2) How do I get an instance of IWhatever?

Many thanks.

I don't have Access installed, but I assume Word is somewhat similar.
So, here we go:

(Ah, some progress)

Ok, None is not accepted.  Grepping in the comtypes\gen directory for 'ReferencesEvents'
I find this code snippet in file '_0002E157_0000_0000_C000_000000000046_0_5_3.py':

Events._methods_ = [
    COMMETHOD([dispid(202), 'propget'], HRESULT, 'ReferencesEvents',
              ( ['in'], POINTER(VBProject), 'VBProject' ),
              ( ['retval', 'out'], POINTER(POINTER(ReferencesEvents)), 'prceNew' )),
    COMMETHOD([dispid(205), 'propget'], HRESULT, 'CommandBarEvents',
              ( ['in'], POINTER(IDispatch), 'CommandBarControl' ),
              ( ['retval', 'out'], POINTER(POINTER(CommandBarEvents)), 'prceNew' )),
]

So, it seems we need a POINTER(VBProject).  VBProject is a CoClass, implementing the
_VBProject COM interface.

Further grepping shows the comtypes\gen\VBIDE.py is an alias module for
comtypes\gen\_0002E157_0000_0000_C000_000000000046_0_5_3.py, so we use the
former because it is much easier to type:

>>> from comtypes.gen import VBIDE
>>> from ctypes import POINTER

>>> acc.VBE.Events.ReferencesEvents(POINTER(VBIDE._VBProject)())
<POINTER(_ReferencesEvents) ptr=0x274f2c at 11c7490>
>>>

(The idiom 'POINTER(VBIDE._VBProject)()' creates a NULL-pointer to _VBProject)

And finally we try to find some events:

>>> ShowEvents(acc.VBE.Events.ReferencesEvents(POINTER(VBIDE._VBProject)()))
# event found: _dispReferencesEvents_ItemAdded
# event found: _dispReferencesEvents_ItemRemoved
<comtypes.client._events._AdviseConnection object at 0x011BACB0>
>>>

Now, I do not know what I have to do to trigger these events, but
it looks like the code could possibly work.

hi all. thanks for the reply, mark. no, i didn't install it in "\Program
Files" -- it put itself in the default location, "\Python26" and i also went
back to do a complete uninstall/reinstall. i ran a "python -O pyscript.py"
to update the .pyc and .pyo files and then rebooted the web server. still
the same error.

mark, what's the scoop with the python dir or the virtualization you
mentioned? the install was default but if there are permissions or something
that need to be a certain way i'll definitely look into it. otherwise i
think this is our last gasp with python/asp for now.

thanks,

matt

as a follow-up, i can now get it to work on my personal computer running
windows xp using the normal installation steps. the server i'm trying to get
it installed on is an old server running windows server 2003 and perhaps it
just has a bunch of other conflicting things that are causing the problems.
we'll have to look into those next.

so if you have any thoughts based on my prior emails or perhaps operating
system integration, wonderful. but otherwise i think we have to start
looking at our server for conflicts.

thanks for your help.

This is on Windows XP and Vista both.  It sometimes happens once then
not again for 50 tries.  Sometimes it happens 5 times in a row.  It
appears that an "OLE Error 0x80041002" is an "object not found error".
So the query is running and line 86 in util.py is trying to get the next
result from the query and is bombing out?  For some reason it things
there are more results then there actually are?  This code is a direct
port from working Perl code.  Anyone have any ideas?

To make talking about it easier, I've slightly reworked
your code to make it run completely (ie I've added imports and
the initialisation of the data structures) and 
to take advantage of the wmi module's built-in features.
Hopefully it's perfectly clear what's going on; I've just avoided
some of the more "raw" wmi in your code.

I've also turned off find_classes as you don't really want this
in running code; it's more for use the interpreter. The latest
version of the module 1.4 turns this off by default which makes
the startup time much faster.

<code>
import wmi

services = wmi.WMI(privileges=["security"], find_classes=False)

serials = {}
serials_reversed = {}
drive_letters = {}

for disk in services.Win32_PhysicalMedia():
  serials[disk.Tag] = disk.SerialNumber
  serials_reversed[disk.Tag] = disk.SerialNumber

for physical_disk in services.Win32_DiskDrive():
  for partition in physical_disk.associators("Win32_DiskDriveToDiskPartition"):
    for logical_disk in partition.associators("Win32_LogicalDiskToPartition"):
      drive_letters[logical_disk.DeviceID.rstrip(":")] = physical_disk.DeviceID

print serials
print serials_reversed
print drive_letters

</code>

FWIW, the physical-logical drive stuff is straight out of the
Cookbook page:

I've managed to produce this error by having the script running
continuously and then inserting a USB stick -- watch the serials
dictionary grow -- and then "ejecting" it, at which point, the
WMI query obviously gets caught out between what it thinks is
there and what is there when it comes to query. It's essentially
a race-condition, I suppose.

Given that this can happen, I can only suggest you catch the
exception, look for the specific 80041002 error code and
ignore it / log it. This is assuming that the circumstances
in which you're running it make it likely that the insertion
or removal of another physical disk is a plausible cause.

Yes,  I'm finding this error in a similar situation.  A SATA relay is 
connecting the drive to the PC running the WMI code about 5 seconds 
before.  It seems to me I just need a longer delay between the relay 
switch and this code executing.  Thanks for the tips and code cleanup.

Subject: [python-win32] making icons on task bar require double-click
Message-ID: <4AE078D2.1080600@inteli-com.com>

Is it possible, with a python program, to run through the task bar icons 
and change them so that their current single-click event would get 
transferred to a double-click event?  I click them by mistake sometimes 
and its very annoying to wait for the program to open just so I can 
close it.  I haven't been able to find a way to accomplish this natively 
so I figured a python script set to run when my user logs in and the 
windows extensions might do the trick.

Thanks.

In short, no.  This requires an injectable window hook, and there is at
present no way to do that kind of window hook in Python.

How do you happen to click on these accidentally?  Perhaps there are
other ways to solve this.  For example, you can configure the taskbar so
that it hides itself unless you hover the mouse at the bottom of the
screen.  Or, you can drag the taskbar to any other edge of the screen. 
If you find yourself hovering around the bottom edge most of the time,
perhaps moving the taskbar to the top would solve that.

A search turned up the following page:
http://msdn.microsoft.com/en-us/library/ms724509%28VS.85%29.aspx

The remarks section indicates that the function is in ntdll.dll rather 
than kernel32.dll, which would explain the attribute error for the 
ctypes case.

When using ctypes, the MSDN reference pages are frequently the best 
available source of Windows API references, if you haven't got the 
platform SDK installed.

As I understand, while PyWin32 wraps a lot of API functions it doesn't 
wrap everything; if it's not wrapped, ctypes is your only option.

Yep, that will give you an AttributeError...

You want to be looking in "ntdll", not kernel32.

eg. ctypes.windll.ntdll.NtQuerySystemInformation

But that's only to get you partway there.  Next you'll need to
implement the SYSTEM_INFORMATION_CLASS structures, to provide as
parameters.

MSDN has some info on this function:
http://msdn.microsoft.com/en-us/library/ms724509(VS.85).aspx

But, wow... Just starting with windows programming, and jumping right
into the semi-documented territory.  Brave. :)

Thanks!  I did search, but I guess I didn't know to look at the MSDN

Ayup.

Well, I have three things going for me:

* I've been programming in Python for more than a decade

* I've been programming for more than three decades

* I have code in C++ that does exactly what I want (I'm rewriting it in
Python because for some strange reason AVG thinks the executable is a
virus and we also have some other problems running it on 64-bit Vista,
and I figure that using Python will work better), and I just need to
translate all the Windows calls

Oh, wait, I have four things going for me:

* The wonderful Python community

Oh, wait, I have [stops Spanish Inquisition re-run here]

Subject: [python-win32]  change PAMIE to win32 interface problem
Message-ID: <26020853.post@talk.nabble.com>


hello,
currently im making some web scrap script.
and i was choice PAMIE to use my script.
actually im new to python and programming.
so i have no idea ,if i use PAMIE,it really helpful to make script to relate
with win32-python.
ok my problem is ,
while im making script,i was encounter two probelm.
first , i want to let work my script Beautifulsoup and PAMIE.
so i was googled, and only i can found 1 hint.
follow script is which i was found in google.
but it not work for me.
im using PAMIE3 version.even if i changed to pamie 2b version ,i couldn't
make it working.

from BeautifulSoup import BeautifulSoup
Import cPAMIE
url = 'http://www.cnn.com'
ie = cPAMIE.PAMIE(url)
bs = BeautifulSoup(ie.pageText()) 

and follow is my script. how to make it to work ?
from BeautifulSoup import BeautifulSoup
from PAM30 import PAMIE

url = 'http://www.cnn.com'
ie = PAMIE(url)
bs = BeautifulSoup(ie.pageText()) 

my second problem is,while im making script,i think sometime i need normal
IE interface.
is it possible to change PAMIE's IE interface to just normal IE
interface(InternetExplorer.Application)?
i don't want to open new IE window to work with normal IE interface,want to
continue work with current PAMIE's IE windows.
sorry for my bad english 
Paul

To answer your question slightly obliquely, can I offer you:

http://winsys.googlecode.com/svn/trunk/random/file_handles.py

which is, I think, coming close to what you want and will at
least illustrate the way of doing it. AFAICT you don't need
a Google sign-in or Javascript to access that code, but if 
you have any problems -- philosophical or technical -- let me
know and I can email you a copy directly.

This can be accomplished with the wxPython lib.

I apologize.  I think I misread what you are trying to accomplish.  It  
sounds like you want to do this for icons that you did not create.  I  
do not think this is possible with wxPython.

I apologize.  I think I misread what you are trying to accomplish.  It  
sounds like you want to do this for icons that you did not create.  I  
do not think this is possible with wxPython.

Subject: [python-win32] Paste Values only in Excel Paste Special
Message-ID: <a8750f690910230532q3ee57a6et7d87399e05d56361@mail.gmail.com>

Hi everyone,

I followed (or I think I have) the advice from
http://www.mail-archive.com/python-win32 at python.org/msg06368.html
but I  get an error when I am trying to Paste the values only from a
spreadsheet. I simply want to increase the date in column A by one day. To
do this, I insert a formula and then I'd like to paste the values from the
column where I inserted the formula so I can get rid of the columns I don't
need. The code works up to the last line but it errors when I issue the
PasteSpecial command. I used terms like constants.xlPasteValues in the code
to make it more comprehensible to the list. I am also aware that the use of
syntax like Range("A2:A49") is normally frowned upon but this is just a
small piece of code to show my problem.

Thanks in advance

Paolo

Can you provide a traceback?  What error are you seeing?

Tim,

Thanks for your response.  I think I may have been using the wrong 
term.  I like the normal windows taskbar on the bottom of the screen.  
What has happened to me though is that my quick launch has grown so 
large that I have put it at the bottom of the taskbar with the open 
windows above it.  The way I accidently click the quick launch icons is 
that when I go to switch to another window, I overshoot the window 
"tile" and hit a quick launch button instead.  To solve this problem 
initially, I moved the quick launch toolbar to the top of the screen and 
set it to remain on top.  However, some programs don't honor this and 
end up behind the toolbar, which is very annoying.

I guess, if its not possible to modify the quick launch icons, that is 
ok.  I can live with it.

Thanks again for your response.

Wow!  Thanks!  Now that I know more what to look for, I did some
searching and found this post that had no response:

http://mail.python.org/pipermail/python-win32/2009-June/009268.html

Assuming that I only care about monitoring open files within a single
tree, should I be concerned that your code might not return all open
files?

That is better explained...I still don't think you could modify the
behaviour of the quicklaunch, but here are some suggestions:

1) Write a custom explorer toolbar. You may be able to use PowerPro for this
(http://powerpro.webeddie.com/)
2) Use Launchy or something like it instead of quicklaunch.

3) Write a python script to scan your quick launch dir, replace every
shortcut with a link to itself (with a customized icon), and launch the
intended program only when one of the new shortcuts is clicked twice in
short succession. (haha that should keep you busy).

4) Upgrade to Windows 7, which negates the need for a quicklaunch anyway.

5) Make your quicklaunch bar smaller, and use the little double-arrow-menu
as a pop-up quicklaunch instead of having all icons showing.

Some of those might be helpful, some not.

There are some good suggestions in there.  The first two look very

Yes, your name is famous in the Python community.  As we say, "your
reputation precedes you."  However, Christopher's comment is not without
merit, and is worthy of a little explanation.

The Windows NT family is really an operating system within an operating
system.  The kernel is a more-or-less generic operating system of its
own; user programs run within a "subsystem" running on top of that
kernel.  In the original implementation, this distinction was extremely
pure.  There was a Win32 subsystem, an OS/2 subsystem, and a Posix
subsystem, all exclusively in user mode.  Programs written for those
subsystems used their own APIs, and the subsystem translated them into
"native" calls for the kernel.  That purity has been tarnished a bit
(mostly for performance reasons), so that some Win32 concepts have been
forced down in the kernel, but the basic idea is still present.

All of the APIs starting with Nt and Zw, including
NtQuerySystemInformation, are "native" calls.  They are not Win32
calls.  They are intended for use in the kernel, although many are
exposed to user-mode as well.  The native API looks somewhat different
from the Win32 API, and is not nearly as well documented.  There are
many useful things to be done with those APIs, but there are many sharp

It is quite possible that AVG is generically objecting to the use of
native APIs.  If so, I fear you will reach the same frustration with
your Python translation.

That just shows what a dinosaur I am.  I hate the Quick Launch bar, and
have turned it off completely.

Subject: [python-win32] using WMI to get processor flags...
Message-ID: <36dec4ff0910231321q508dcc2br9b71d650b136fa2e@mail.gmail.com>

First, Thanks again Tim Golden :)

I've gotten a lot of use out of WMI so far, though I'm still trying to
get an actual list of WHAT I need as far as system info for this tool
I'm writing.

Now I've got another question that I hope someone can provide the
answer I want, not the one I'm afraid is coming ;-)

So I've been looking at Win32_Processor and it provides a lot of
processor information that I need, like max speed, cpu stepping,
family ID and so forth, and I can also get packages, cores, and
logical counts.

What I haven't been able to find is a way to get a listing of
processor flags (like FPU, MMX, SVN, VMX, SSE3, HTT, etc).  Is there a
way to do this without resorting to pycpuid??  Pycpuid can give me
this stuff but it requires some compiling for systems, and I'm still
not positive that it will work across platforms (AMD v. Intel).

Any thoughts?  I haven't found an answer yet.  I've also looked at
CIM_Processor, but it seems to me that the CIM classes are identical
to the Win32 classes, at least in most cases.  I haven't dug TOO
deeply into CIM_Processor though...

Cheers
Jeff

Have to confess that I don't usually work at this level, and as others
have pointed out, this is undocumented stuff... The de facto authority
is sysinternals, but none of that is Open Source so I don't really
know why their handle.exe picks up more files than my code. :(
I was sort of hoping that someone like Tim Roberts -- who works
with device drivers -- would have a hint.

Obviously, the answer would depend on the parameters of what you're
trying to do and how much margin of error you have. One definite
gotcha I wasn't totally able to work around -- although the code in
can_access is trying -- is the issue that attempting to query for
a pipe handle can hang the thread altogether. I believe that the
poster in the thread you refer to above didn't have any such problem
(we had a private correspondence which led up to that post).


If you believe that your C++ code is definitely working and you're
free to post it up, I for one am happy to help you translate it.
Maybe that's an option...

Yes, I know -- I was being flip.  OTOH, I've written Java programs
without knowing Java and C DLLs without really knowing C; although I'm
very happy to be a Python expert, I'm also comfortable doing cargo cult
programming, and I'm pretty good at it.

In this case, I don't have a lot of other options, so I'm just forging
forward as best I can.

That seems unlikely, but I'll definitely keep that possibility in mind,
thank you.

Perhaps it would be better to think more strategically.  I don't actually
care about the list of open files.  What I care about is a list of files
that I want to process and checking whether any of them are open.  What
would be the canonical way of doing that on Windows?  It doesn't matter
whether it is in batch or file-by-file.

Hah.  We have no reason to believe that the code is working (other than
the fact that it appears to work), but I'm attaching it in case you find
it useful.  If you want the whole project, I can get that, too.

Wouldn't the least-effort solution be simply to try to open each file,
and see if the open succeeds?

We used to do that, but it was interfering with other programs.  (It's
similar to backup, and we don't want to interfere with e.g. Excel, which
previously was an issue if someone had an open spreadsheet and tried
saving it while we were uploading it.)

I suppose we could switch to using Volume Shadow Copy, I'm not sure why
we didn't try that earlier.

The CIM_ classes represent the DMTF Common Information Model [1],
the structure on which WMI is based. In principle other manufacturers
could implement WMI -- or whatever they would want to call it -- but
as far as I am aware, no-one has.

I'm a little surprised that Microsoft -- who provide sample code [2] for
performing a CPUID check/call -- haven't used that code to provide
such information to WMI, but it doesn't look as though they have.

you can definitely use IE to and innerHTML() to get the HTML, then use
BeautifulSoup to parse the HTML.  What are you having trouble with?

Message-ID: <3ac7f86f0910240729g317a1bdas6f35993b144f9bd3@mail.gmail.com>

Hello,

I attempted to install pywin32 build 214 for Python 3.1.1 and I recieve this
trackback after the install completes:

Traceback (most recent call last):
  File "<string>", line 601, in <module>
  File "<string>", line 329, in install
  File "<string>", line 15, in write
AttributeError: 'NoneType' object has no attribute 'write'

If I try to import a pywin32 module I get this ImportError:

    import win32gui
ImportError: DLL load failed: The specified module could not be found.

Anyone know how to correct this?

Subject: [python-win32] win32pdhutil.FindPerformanceAttributesByName() on
	64-bit Vista?
Message-ID: <fb063bee0910250351t4e8648c9qa84e58efd47d640b@mail.gmail.com>

Hi all,

I have the following lines as part of a larger app, which form part of
a function for terminating processes (as per an example in the pywin32
package dir):

import win32pdhutil
win32pdhutil.FindPerformanceAttributesByName("System")

It seems that on 64-bit systems [1], even with the full Python stack
running in 32-bit mode quite happilly, this fails with the following
message:

Traceback (most recent call last):
  File "pdhutil.py", line 3, in <module>
    win32pdhutil.FindPerformanceAttributesByName("System")
  File "C:\Python25\Lib\site-packages\win32\lib\win32pdhutil.py", line
77, in FindPerformanceAttributesByName
    if object is None: object =
find_pdh_counter_localized_name("Process", machine)
  File "C:\Python25\Lib\site-packages\win32\lib\win32pdhutil.py", line
42, in find_pdh_counter_localized_name
    return win32pdh.LookupPerfNameByIndex(machine_name,
counter_english_map[english_name.lower()])
KeyError: 'process'

I am happy to go and try to debug this (even with no "real" win32 API
experience) but if there is something obvious that I'm doing wrong
here I would love to know.  This works on 32-bit Windows XP and Vista.

[1] The only 64-bit system I have access to at the moment is Vista,
but that seems to be the only apparent difference between this error
occurring and not occurring.

Regards,
Wayne

Have you tried opening the files for exclusive access (ie no sharing) ?

If you decide to use Volume Shadow Copy, I've wrapped some of the
IVss* interfaces for Python, enough to be able to backup selected files
from a volume.  Bear in mind that if an application has a file open for
writing and is not VSS-aware, you may get the file in an inconsistent state.

That's exactly what was causing the problems.  (From what I understand,
this was before I joined the company.)

Yeah.  Plus I've done some research and because our software tries to run
backups in "realtime" I think the performance hit of VSS won't be
acceptable.  We really want to find out which files are open so that we
can skip them until later.  I'll just run with Tim Golden's code for now.

Unless I'm missing something, why do you need Internet Explorer at  
all?  You can get the HTML using urllib2:

import urllib2
response = urllib2.urlopen('http://cnn.com/')
html = response.read()

then extract what you're looking for with beautiful soup:

from BeautifulSoup import BeautifulSoup
soup = BeautifulSoup(html)

for content in soup.findAll('div', class="cnn_sectbincntnt2"):
     if '<a href="/money?cnn=yes"' in content:
         print 'MONEY!'
         print content

You can get a lot fancier finding the money section, but that's the  
gist of it.  And, no IE necessary.

Hi

I want to know to that is any compiler there that could produce asn parser
in python. actually i have an asn file and i want to decode asn base encoded
message.
I found an asn1c compiler that can generate output files that can be used to
decode the message, but those files are in C or java. i want it in python.

Thanks & Regards

You can just use Shell or AdvShell[1] to run python.exe and the script
name as parameter; If you have the associations that the python
installer setups you might just be able to use just the script name.

That could mean a couple of things.  If you just want to invoke a Python
script as a separate process, then it's exactly like calling any other
standalone application.  There are many, many examples of doing that it VB6.

However, if you want to call a Python function from inside VB6 as if it
were a DLL or an object, that's a little more complicated.  The best way
to do that is probably to turn your Python script into a COM object, and
call the COM from VB6.

Well, there's this project:

http://pyasn1.sourceforge.net/

which includes BER, CER, and DER codecs, but it doesn't look like it has an
ASN compiler.

Somewhat tangential to the conversation, but WBEM/CIM is available for
Linux, Mac OS X, some Unices, and Netware:

In case anyone is interested.

Interesting: is it widely used / known / supported, do you know?

Well, I don't really know from personal experience, I just recalled having
found it a while back, I thought it might be useful for a project that never
ended up happening.  From the web page, it's maintained by a company called
Quest Software, Novell is a contributor and apparently uses it in SUSE SLES
10, Apple Remote desktop is listed as using it.

Makes me think it's probably pretty solid, though as I said, I've never used
it myself.

I don't know of a way to get this with WMI, though it _might_ be possible.

You might try looking at this page for some ideas:
http://www.codeguru.com/cpp/w-p/system/hardwareinformation/article.php/c9087__2/

It gives 3 ways to get processor information:
- assembly (pycpuid uses this)
- registry (there is a key in the registry that stores this info, but it
looks like it's all ORd together, so you'd have to decode it)
- Platform SDK ( IsProcessorFeaturePresent() is probably the function you
want )

The page has some C++ sample code, which might help you some.  I'd probably
either try to read the info from the registry (though you can't be 100% sure
the registry is correct, of course), or figure out what C functions to call
and wrap them up in ctypes calls.

How to integrate this with your WMI code (is it querying remote machines?)
is up to you. :)  But feel free to ask if you need ideas.

Subject: [python-win32] Is it possible to (un)check items in "Local Area
 Connection Properties" ?
Message-ID: <4AE8B605.8020400@gmail.com>

hello,

For connecting though CheckPoint VPN,
I need to check the item "Check Point SecuRemote" in the Local Area 
Connections Properties.

I couldn't find a way to read and or toggle this switch (through some 
registry setting),
so I made an AutoIt program to accomplish the task.

The main disadvantage is that if the number of items above "Check Point 
SecuRemote" changes,
the Auto-It script will (un)check the wrong item.

thanks,
Stef Mientki

There are some python tools that do desktop automation in a fashion similar
to what AutoIt does, but this kind of task is one of the few I actually
don't usually use Python for.  I usually use AutoIt.

PyWinAuto (http://pywinauto.openqa.org/) is probably the best-known of the
windows solutions out there.  I thought there was another main one, but I
can't find it at the moment.

Before you go haring off looking for a new tool, have you tried getting the
control ID using the AutoIt Winspy-thingy?  I've been able to use that to
send messages directly to individual controls, rather than the window, which
has helped me in similar situations.

Hope this helps, and let us know how it works out!

Message-ID: <59ce684e0910281611i308eb327q36a030eec0fdf42a@mail.gmail.com>

Hi! Installed Win 7 x64 (replaced win xp x86) this week.  My python
software (free poker database / fpdb) has been working just fine
since.  However, i start it up today, and now I get:

***Error: get_nt_exe(281): (299, 'GetModuleFileNameEx', 'Only part of
a ReadProcessMemory or WriteProcessMemory request was completed.')

This link here http://winprogger.com/?p=26
seems to indicate that that is normal when trying to get process
information about a 32-bit exe from a 64-bit.  However, python is
32-bit, and the exe that i'm trying to get info from is 32-bit.
*shrug*

It also indicates that a newer API called GetProcessImageFileName
should be used.  I don't see this as being within pywin32.  Is it
hidden somewhere?

I updated my autoit script ( whole lot of trial and error :-( ,
but it works now, the spy tip was a good one !!
