 Hi, The following code works perfectly well on one of my machines, but
gives me an error on another: iTunesApp =

iTunesApp.LibraryPlaylist
tracks = pl.Tracks
myTrack = tracks[0] myNewList = iTunesApp.CreatePlaylist("My New List")
myNewList.AddTrack(myTrack) I get the following error message: Microsoft

I'd guess that one box has had makepy run for that type-library, but the
other hasn't.  Look into using the win32com.client.gencache module to
programatically generate makepy support, and it should then happen
everywhere you run it.

Greetings,

In Chapter 12 of "Python Programming on Win32" there is a sample code
demonstrating how to expose a python module in a COM server.  A function
named FixArgs is used in the example to convert Unicode string to ascii
string.  I'm guessing this is no longer necessary for the recent versions of
python.  Btw, I'm using version 2.5. Can anyone confirm this? Thank you.

That's correct - it is no longer necessary to convert unicode to ascii for
pywin32's sake.  You may have other reasons to perform either that
conversion or a completely different conversion, but again, not because
pywin32 insists.

Cheers,

Mark

Subject: [python-win32] Setting object values that are an object (win32com)
Message-ID: <17863.56235.359000.334249@gargle.gargle.HOWL>

I'm using win32com.client to access WMI (via SWbemServices).  Much of
it works -- very nice.

There are two things I'm trying to do that I can't get to work right.
Or rather, two approaches to the same thing, neither of which work.  I
tried to dig through Microsoft docs to figure this out, but that
didn't help.

I'm dealing with a class (MSiSCSIInitiator_TargetClass).  I have an
instance of that class (output of an InstancesOf call in
SWbemServices).  According to the class definition -- and a browser I
have agrees -- that class has a LoginOptions property, of type
MSiSCSIInitiator_TargetLoginOptions. 

In theory, I can set that property and then call the Login method of
the Target class, or I can pass a LoginOptions argument into the
Target.Login method instead.

I tried both.

1. I assume that what I have to do is create an instance of the
TargetLoginOptions class, fill that in, then set the LoginOptions
attribute of the Target class to what I just created:

                C = wmi.Get ("MSiSCSIInitiator_TargetLoginOptions")
                opts = C.SpawnInstance_ ()
                opts.Username = taskfile.user_name
                opts.Password = taskfile.password
                opts.AuthType = 1  # CHAP
                tp.LoginOptions = opts
                tp.Login ()

I get a "generic error".  From the behavior of the rest of the system,
it looks like the operation is attempted, but the outcome is as if the
LoginOptions had not been present.

2. Since the Login method has a set of inputs, one of which is
LoginOptions, I tried passing "opts" that way.

The intuitively obvious syntax is:
		tp.Login (LoginOptions = opts)
but that doesn't work.  It looks like method invocation knows about
positional arguments but not keyword arguments.

So I read an MSDN article that talks about constructing input
arguments.  It translates to this:

                ip = wmi.Get ("MSiSCSIInitiator_TargetClass"). \
                     Methods_ ("Login").inParameters.SpawnInstance_()
                ip.LoginOptions = opts
                tp.Login (ip)

Same result: no luck (operation is attempted but it acts as if
LoginOptions was not present.

I also tried changing the last line to:
	        tp.ExecMethod_ ("Login", ip)

Almost the same result -- a "Generic Failure" exception, but this time
it appears that the operation was not actually attempted.

Does anyone have any idea where I can go from here?

Hello.

I'm following 
http://aspn.activestate.com/ASPN/Cookbook/Python/Recipe/52267 to open a 
local .mdb file and export the contents. It works with normal databases, 
but I cannot open a password protected database.

According to http://www.oreilly.de/catalog/progacdao/chapter/ there is 
no password option in the OpenDatabase method, so I've tried using 
daoEngine.DefaultPassword = xxxx without success.

Does somebody know if this is possible and how?

I've found a visual basic example using Dao and the password is passed 
as an attribute string. Hence the following will work under python:

   daoEngine.OpenDatabase(infile, False, False, "MS Access;pwd=xxxxx")

You want to try visiting:

http://www.connectionstrings.com/

where, for example, you will find:

Provider=Microsoft.ACE.OLEDB.12.0;Data 
Source=C:\myFolder\myAccess2007file.accdb;Jet OLEDB:Database 
Password=MyDbPassword;

as a connection string for Access.

How did you create the scheduled task?  By default, "at" tasks run as
the special user called LOCAL_SYSTEM, which doesn't have access to your
registry nor any of your network shared drives.  If you create the task
with the Control Panel Scheduled Task Manager, you should be able to
choose the username for the task.

Why would you use the Windows script host to run this, instead of just
invoking pythonw.exe?  I've had great success running "at" tasks by
invoking Python directly.

Hi all,

I'm new to the list (and Win32 programming) and glad to be here.

I've got a Python app that's running as a Windows Service. I'd like it
to be paused and continued (or possibly stopped and started, haven't
quite decided yet) when the machine it's installed on enters Standby or
Hibernate mode. Can anybody point me in the right direction so I can
learn how to register to receive those events and handle them within my
service script?

I've never used this particular object, but from general principals try something like:

opts=tp.Methods_ ("Login").InParameters
opts.Properties_('Username').Value=taskfile.user_name
opts.Properties_('Password').Value=taskfile.password
opts.Properties_('AuthType').Value=1  # CHAP
tp.ExecMethod_('Login',opts)

Someone asked something quite similar on c.l.py recently:

The second responder does point out that the whole point
of the suspend/hibernate operations is that the programmer
doesn't have to do anything: his program state is saved and

Message-ID: <d5ff27200702080823l674ae7ffq70255cacd7d523ff@mail.gmail.com>

Hi All,

    I have a very simple python script that tries to put a rectangular
shape in a worksheet and then add some text inside that shape. The
main problem, is that as usual Excel doesn't like input strings longer
than 200 and something characters. So, By just recording a macro in
Excel, I tried to append the text in the shape by dividing it in
chunks. For example, I tried this little script:

#----------------------------------
from win32com.client import Dispatch

finalText = "A"*1250

xlsapp = Dispatch("Excel.Application")
wb = xlsapp.Workbooks.Add()
sheet = wb.Sheets[0]

myShape = sheet.Shapes.AddShape(1, 315, 200, 400, 300)
myShape.Select()

xlsapp.Selection.Characters.Text = finalText[0:200]
xlsapp.Selection.Characters(200).Insert(finalText[200:400])

excelfile = "Hello.xls"
wb.SaveAs(excelfile)
wb.Close()
xlsapp.Quit()

#----------------------------------

And it crashes with an impossible error:

Traceback (most recent call last):
  File "D:\MyProjects\pywin32.py", line 13, in <module>
    xlsapp.Selection.Characters(200).Insert(finalText[200:400])
  File "C:\Python25\lib\site-packages\win32com\client\dynamic.py", line 172, in
__call__
    return self._get_good_object_(self._oleobj_.Invoke(*allArgs),self._olerepr_.
defaultDispatchName,None)
pywintypes.com_error: (-2147352573, 'Member not found.', None, None)

However, the macro I recorded in Excel does exactly that: it appends
chunks of the string with a maximum length of 200 chars.
Am I missing something here?

Subject: [python-win32] Win98 - exceptions.IOError: (13, 'Permission denied')
Message-ID: <1170954603.11993.1.camel@eriador>

Hi to everyone,

I have a Service, that runs on a WinXP machine. The service read a file
on a Win98 machine and write the content in a file on the WinXP machine.
After tree times I get the error message exceptions.IOError: (13,
'Permission denied'). 

The following things I have already tested:

- The file on Win98 machine could be deleted, so the file is closed
correctly.
- Stop an restart the service on WinXP, will have no effect
- Reboot the Win98 machine solve the problem for three times. So I have
the same issue explained above.
- I have changed the intervall from 5 sec to 1 minute. After ther first
time I get the error message.
- Using a Win2000 or WINXP machine instead of the Win98 machine. That
works. But unfortunatly the PC to access is a Win98 and I have no
influence to decide for upgrade.

I can't figure out, what's the problem.

Thanks! I've been doing Python network programming on *nix for a few
years now, so it'll be nice to expand my platform experience.

Thanks for the tip (and the TinyURL!). Yes, my service involves network
connections, and while my server and client are robust against non-sleep
outages, this will give me the chance to do a little cleanup that will
keep things tidier without waiting for keepalives to time out.

I hope you don't mind doing a little hand-holding, since I have zero
experience with Win32 and am therefore bumbling about.

I looked at this:

http://msdn2.microsoft.com/en-us/library/aa394362.aspx

Which leads me to believe that the right way to do this is somewhere
along these lines:

class MyPowerClass(object):
    def __init__(self):
        if self.EventType == 4:
            print 'suspending'
	elif self.EventType == 7:
	    print 'resuming'

DispatchWithEvents('Win32_PowerManagementEvent', MyPowerClass)

Of course that's wrong, since I expect in __init__ EventType hasn't been
set yet, but am I close?

Since this is running as a service, I'm busy doing other things in a
thread, and I want to avoid polling for status. So basically what I'm
looking for is a way to register one of my methods to be called with a
power event.

Thanks for your help so far,

Steve

Sadly, no. Nice try, though ;)

What you're looking at is WMI. Very useful, and a kind of unified
answer to all sorts of sys-adminy things. But it while it is
COM/DCOM-based it doesn't operate like a normal COM class, which
is what you're describing below (ish).

In short you'd need to do something like this:

<code>
import win32com.client

wmi = win32com.client.GetObject ("winmgmts:")
power_watcher = wmi.ExecNotificationQuery (
   "SELECT * FROM Win32_PowerManagementEvent"
)
power_event = power_watcher.NextEvent ()

event_type = power_event.Properties_ ("EventType").Value
if event_type == 4:
   # etc.
elif event_type == 5:
   # etc.

</code>

That's pretty much untested but it's along the right
lines. I'm the author of a helper WMI module which I
know a number of people find useful in this area:

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

but in this case (a) I have embarrassingly little support
for extrinsic events (which this is) although it's on my
todo list and (b) it would be slightly overkill if all you
need to do is what I've shown you above.

That said, if you want to go the WMI module line, I'm
quite happy to try to make things work there for what
you need. As I said, I'd already decided I needed to
do something in this area.

Sorry this is a bit rushed; you've caught me on a really
busy evening.

Subject: [python-win32] win32com confusion: PROPERTY with arguments vs.
	METHOD.
Message-ID: <30554403.1171020143751.JavaMail.ngmail@webmail12>

We use an IVI-COM Server for an Agilent power supply. 

The documentation defines "Status.Register" to be a PROPERTY, but also specifies arguments to be used when calling it (apparently a rare case we haven't come across before). 

Init code: 
>>> import win32com.client 
>>> o=win32com.client.Dispatch("AgilentN57xx.AgilentN57xx.1") 
>>> o.Initialize('UsbDevice1', False, True) 

It looks like "Status.Register" was a bound as a METHOD in win32com: 
>>> o.Status.Register 
<bound method CDispatch.Register of <COMObject <unknown>>> 

Trying to assign a value to it raises an exception: 
>>> o.Status.Register = 1 
Traceback (most recent call last): 
File "<interactive input>", line 1, in ? 
File "C:\Python23\Lib\site-packages\win32com\client\dynamic.py", line 543, in __setattr__ 
raise AttributeError, "Property '%s.%s' can not be set." % (self._username_, attr) 
AttributeError: Property '<unknown>.Register' can not be set. 

The exception suggests that it really is a PROPERTY. 

Calling the "PROPERTY" as specified to read the power supply's status register (with main type=3, subtype=0) also raises an exception: 
>>> o.Status.Register(3,0) 
Traceback (most recent call last): 
File "<interactive input>", line 1, in ? 
File "<COMObject <unknown>>", line 2, in Register 
com_error: (-2147352573, 'Member not found.', None, None) 

We stepped through dynamic.py and it seems that 'win32com' gets confused in this case and mixes up METHOD and PROPERTY handling. 

All other COM METHODS and PROPERTIES work fine. 

Is this a win32com bug, or a misunderstanding on our part? 

Can anyone suggest a workaround? 

We use:
PythonWin 2.3.5 (#62, Feb 9 2005, 16:17:08) [MSC v.1200 32 bit (Intel)] on win32.
Windows 2000

Many thanks for your help !

FWIW, I've just patched the wmi module to support extrinsic
events such as the PowerManagementEvent and DeviceChangeEvent
(useful for spotting when a USB stick has been removed). It's
not up the website yet, but if anyone wants to give it a go,
let me know.

Message-ID: <BAY116-F311927AAB4C3A26FBBE07F959C0@phx.gbl>

So I have a function that ries to add a record:

    def EntryAdd(self, dataDict):
        try:
            self._DBConn.MoveFirst()
            self._DBConn.AddNew()

                self._DBConn.Fields.Item(key).Value = value
            self._DBConn.Update()
        except pywintypes.com_error, e:
            print e
            print 'error text here'
        return True

So if the error already exists I get an exception, no problem, I handle and 
log it.

The problem here is that anything I now try to use this recordset for will 
throw an exception. Is there any way to recover from this without recreating 
the whole recordset?

Thanks

This looks like one of those odd properties that takes parameters.
There's a method for dynamic dispatches that you can use to
force it to be treated as a method:

s=win32com.client.dynamic.DumbDispatch(xlsapp.Selection)
s._FlagAsMethod('Characters')
s.Characters(200).Insert(finalText[200:400])

It's kind of hard to tell without a traceback, but at a guess
it looks like the offending record created with AddNew is
never removed from the recordset after the error occurs.
CancelUpdate() should get rid of it.

In general, you should try and be specific about handling exceptions.
Assuming you want to only handle "record exists" type exceptions, you should
probably write something closer to:

     def EntryAdd(self, dataDict):
         self._DBConn.MoveFirst()
         self._DBConn.AddNew()
         for key, value in dataDict.items():
            self._DBConn.Fields.Item(key).Value = value
         try:
             self._DBConn.Update()
         except pywintypes.com_error, e:
             hr, msg, exc = e
             if hr != SOME_CONSTANT_MEANING_RECORD_EXISTS:
                 raise
             print e
             print 'record exists'
         return True

I'm not sure what SOME_CONSTANT_MEANING_RECORD_EXISTS is, and it may even be
necessary to unpacl 'exc' to get a reliable error code.  All other errors
will still result in an uncaught exception - so any other errors you have
are not silently handled as if they were the common "record exists".  You
probably still want an outer exception handler that handles all errors in a
sane way

If you can use makepy on your object, you should find 'SetRegister(args)'
works.  Sadly, this isn't supported in objects without typelib support.
I've added the bones of this to the test suite, so let me know if you'd like
to help work on this...

When you have used MakePy on the type library, things are slightly
different for property accessors that take arguments.

For those properties that do take arguments MakePy will generate
accessors for them as methods, prefixed with "Get" or "Set" as appropriate.

If you look in the MakePy generated file for Excel, somewhere in the
"class Range()" definition you will find:

Actually, I do have a lot more exception handling going on. I just tried to 
keep the code simple to demonstrate the problem. But yeah, if I except in a 
way I am not expecting (ie: anything but a record exists) I handle it 
differently.

Thanks for the tips though, and most definatly for making sure I am using 
good practices :)

In general, you should try and be specific about handling exceptions.
Assuming you want to only handle "record exists" type exceptions, you should
probably write something closer to:

      def EntryAdd(self, dataDict):
          self._DBConn.MoveFirst()
          self._DBConn.AddNew()
          for key, value in dataDict.items():
             self._DBConn.Fields.Item(key).Value = value
          try:
              self._DBConn.Update()
          except pywintypes.com_error, e:
              hr, msg, exc = e
              if hr != SOME_CONSTANT_MEANING_RECORD_EXISTS:
                  raise
              print e
              print 'record exists'
          return True

I'm not sure what SOME_CONSTANT_MEANING_RECORD_EXISTS is, and it may even be
necessary to unpacl 'exc' to get a reliable error code.  All other errors
will still result in an uncaught exception - so any other errors you have
are not silently handled as if they were the common "record exists".  You
probably still want an outer exception handler that handles all errors in a
sane way

At work, bringing in an executable to use is no big deal, but installing
anything takes an act of congress.  Because of this, I was going to try to
py2exe everything you get with the windows installer, wxPython, and
pyOpenGL.  My goal is basically a complete python distribution that does not

Is this a pipe dream?

If it's doable, I can figure it out... I just don't want to throw a lot of
time and effort at the impossible.  If anybody's tried this, or knows a good
reason it should/couldn't work, I'd appreciate any feedback you can provide.

I have built and use exe's using win32com for both db access and com API 
interaction, so this part is doable.

I think what you are asking though is not going to work, you basically want 
to take all the libs, all the dll's etc, package them all up with python 
into an exe and just run python and all its stuff from one exe at work? is 
that right?

If so, I would humbly suggest that is not a good idea. I am betting there 
would be more than just performance problems.

What is your definition of "install"?  All that the Python installer
does is copy a bunch of files and create registry entries.  Indeed,
that's all that ANY installer does.

So, you could just zip up your \Python24 directory from home, export a
few keys from the registry, then unzip the zip and import the registry
files on your machine at work.  You would have done exactly what the
installer did, and have a fully functional Python installation.

But what is the point?  The Python installer is just an executable.  If
you can run a py2exe executable, why can't you run the Python installer

I have never tried it myself, but it seems to me that Movable Python is 
exactly what you need (see 
http://www.voidspace.org.uk/python/movpy/introduction.html).

I don't know what's exactly the OP's problem, but in general, asking a  
user to install Python first, then wxPython, then pyOpenGL, and only then  
the desired application may be too much. py2exe is a nice way to package  
all of them.

The OP wanted to have a full Python installation available to him
without actually running the Python installer, apparently to work around
an overly fascist IT department.

Subject: [python-win32] How to assign a value to a property which must be

Message-ID: <45D41F29.8010405@syso.ch>

Hi

I have a "show stopper" with the win32com module. The com object I have
to write a client to, has a interface where the properties show as

(# The method AsCurrencybyName is actually a property, but must be

When I try to assign a value to a object property I get a SyntaxError.
See output of python win below.

Is there a workaround ? What can I do?

Subject: [python-win32] win32file.ReadDirectoryChangesW Missing some events
 even with high heap size?
Message-ID: <45D42823.20905@twitchstudios.com>

Hello,  I have recently written a tool that heavily depends on 
win32file.ReadDirectoryChangesW.

Firstly, It fires potentially hundreds of notifications for a simple 
save operation. And for a windows copy operation it fires virtually no 
resaults untill near the end of the copy.  Point being it was very hard 
for me to determine when actual write operations had finished due to all 
these sporadic events.

1. My first Dilema was trying to work out a way to consider all these 
events as just 1 event.  Is there a flag for this? I ended up writing 
some special filters to filter out all the extra events that follow an 
initial event up untill some condition is met. but I'm wondering if 
there is an easy way to determine when a write operation has actually 
finished? or when a write operation first STARTS. Nothing more.

2. Secondly and more importantly.   Events go missing.  Sometimes i get 
a 'file deleted' event followed by a 'file created' event when i save a 
file, but sometimes i just get a 'file created' event with no 'file 
deleted' event preceding it. Both times i saved the file in exactly the 
same way.  And it appears to be very random when it chooses to skip out 
on not reporting the 'file deleted' event. 

Any ideas as to why some events appear to go missing?  Is 
"ReadDirectoryChangesW " prone to inaccuracy's.  I have tried having 
rather large heap sizes and that does not appear to help.  If 
ReadDirectoryChanges is solid acoording to you guys then i will just 
have to keep trawling through my code to see if its something else.

Here are some snippets from it to show you how i have set up the 
directory watching parameters.

hDir = win32file.CreateFile (
  path_to_watch,
  FILE_LIST_DIRECTORY,
  win32con.FILE_SHARE_READ | win32con.FILE_SHARE_WRITE,
  None,
  win32con.OPEN_EXISTING,
  win32con.FILE_FLAG_BACKUP_SEMANTICS,
  None
)

results = win32file.ReadDirectoryChangesW (
  hDir,
  10000, #Heap Size
  include_subdirectories,
  win32con.FILE_NOTIFY_CHANGE_FILE_NAME| #should return an integer of 1
  win32con.FILE_NOTIFY_CHANGE_LAST_WRITE, #should return an integer of 3
  None,
  None
)

note: there are some loops that run that constantly return the resaults 
of ReadDirectoryChangesW.

i based my code off tim goldens multithreaded directory watcher demo 
found at. (not much difference)
http://tgolden.sc.sabren.com/python/downloads/watch_directory.py

Im going to have an awesome tool once this is done that i hope to share.
Thanks for any insights.

That surprised me, although it does depend on what you
call "a simple save operation". But then I saved a trivial
Word doc (assuming you meant something like that) and
I did indeed see nearly 50 combined update/rename/delete/create
operations going on, presumably as Word does things to
avoid corrupting files etc.

Certainly it's not a foolproof way to determine, say, when
a file has finished being written (a common enough request
on the Python list).

No. You'll need to do some sort of state machine such as
you've outlined below.

Not that I have an answer, but do you have a repeatable code
snippet which illustrates this? I'd like to try it on a different
machine - viz, mine - to see if it's environmental.

I've not used this routine all that much, but my own and other
peoples' experience points to buffer size as being the cause
of lost events. That said, I don't know of any rule-of-thumb
which indicates what might be a good size, and you've already
tried growing it somewhat.

Have you tried searching Google Groups for ReadDirectoryChangesW?
It's almost certainly worth it, because unless there's an issue
with the Python wrapper causing event-loss, it must be something
in the routine itself.

Subject: [python-win32] dbi.dbDate
Message-ID: <45DB0CB3.9090606@chamonix.reportlab.co.uk>

Just came across a weird problem with dbi.dbDate; it seems it is based on the 
32bit time since 1970 used by python's time module. Unfortunately I have 
financial data for a bunch of people with DOB <1940.


Nothing seems to blow up when I execute sql fetches, but the returned objects 
behave very strangely.

eg
 >>> type(objs[5].DateOfBirth)
<type 'DbiDate'>
 >>> str(objs[5].DateOfBirth)
'<interactive input>\x00\x00\x00\x00\x00'

ie it seems to be producing garbage from somewhere in memory.

I'm not sure that I care to use a date system which is so limited, but surely it 
should be able to detect that the date is out of range and raise some kind of 
ValueError or something.

I guess an alternative would be to abandon compatibility with python's time 
module and switch to datetime for the dbDate construction.

Been there.  Done that.  Same reasons.  User's need a custom app but don't
have install permissions due to IT policy.  Just build your py2exe project
and pass it around.  If you're careful  you can even cut out a bunch of the
fluff, e.g. sample files for Tkinter, that py2exe might include.  I found
the best distribution was to zip up the build result, then create a
self-extracting .exe that auto-extracts to the desired directory common to
all user's PCs.  Once they learn where to run it or if you provide them a
handydesktop shortcut in the package, upgrades are a snap.

hello,

is there an easier way to get the name of current process? i'm using
wmi module from Tim Golden. here is what i have:

def find_first_match(func, lst):
    """Find 1st item in a list that yield True for a give function."""
    match = None
    for i, elem in enumerate(lst):
        if func(elem):
            match = [i, elem]
            break
    return match

def get_current_process_name():
    import wmi
    import win32process
    procList = wmi.WMI().Win32_Process()
    hwnd = win32process.GetCurrentProcessId()
    find = find_first_match(lambda p: int(p.Handle) == hwnd, procList)
    if find:
        return find[1].Name
    else:
        return None

if __name__ == "__main__":
    print get_current_process_name()

the above code works. but it is slow. it always takes a few seconds to
get the procList. is it normal?

thanks for your help

I'm quite sure other people can come up with non-WMI solutions,
but just a few pointers on what you have there:

If you know what you're looking for (in this case:
Win32_Process), you can avoid a certain overhead in
startup by passing find_classes=False to the WMI function:

<code>
import wmi
c = wmi.WMI (find_classes=False)
</code>

Then, you can let WMI do the heavy loading of finding
a particular process:

<code>
import win32process
import wmi
c = wmi.WMI (find_classes=False)
current_id = win32process.GetCurrentProcessId ()
for process in c.Win32_Process (Handle=current_id):
   break
print process.Name
</code>

Finally, if you know you only need the name, you can
specify the list of fields to return:

<code>
import win32process
import wmi
c = wmi.WMI (find_classes=False)
current_id = win32process.GetCurrentProcessId ()
for process in c.Win32_Process (['Name'], Handle=current_id):
   break

print process.Name
</code>

It's still not blindingly fast, but timeit gives...

python -m timeit "import win32process; import wmi; print wmi.WMI 
(find_classes=0).Win32_Process (['Name'], Handle=win32proce
ss.GetCurrentProcessId ())[0].Name"

10 loops, best of 3: 67.9 msec per loop

... which might or might not be adequate. Depends on what
you need, and whether this is a one-shot tool or part of
some larger setup where this small startup cost will be
negligible.

It depends on what you mean by 'name'.  Either 'sys.executable' or
'win32api.GetModuleFileName(0)' should give the same(-ish) result as Tim's
script in most cases.

Subject: [python-win32] DynamicProxies for VBA
Message-ID: <loom.20070222T121912-125@post.gmane.org>

Hi guys, I have a couple of newbie questions, as the win32com stuff has been 
my first exposure to python.

I managed to create python com wrappers with a DynamicPolicy, answering using 
_dynamic_ and I managed to create objects responding to methods declared in 
_public_methods_

I am now trying to create a dynamic proxy in python that I can expose to VBA 
and that can deal with arbitrary attribute assignments dynamically.  I tried 
to implement __setitem__ with the defaul policy, but I don't seem to be able 
to get VBA to see it.  I thought this might work under a dynamic policy, but 
everything gets trapped by _dynamic_ instead.

So my questions are:
* how do you get VBA to leverage __setitem__ and __getitem__ ?
* how can I mix _dynamic_ handling of unknown methods with default handling of 
_public_methods_ ?

thanks in advance for your help.. I am looking forward to throw away 90% of my 
VBA code.

I think the datetime module was added in Python 2.3.  Not sure how
long Mark intends to keep building for 2.2.

>From a quick look at the source, it would be relatively simple to convert
to PyTime instead of DbiDate.  This wouldn't be backward compatible

As a workaround, you could format the dates as strings in your SQL.
Alternately, you might want to try using ADO instead of ODBC.

Thank you Tim and Mark.  After trying what was suggested by you (both
work), I realized it is not what I was looking for.  What I wanted to
do is: for every 0.1 second, check the active application or current
application, or active window? (I don't know what is the correct
term.) if it is AutoCAD (meaning user is using AutoCAD), turn on the
CapsLock, if it is Microsoft Word (meaning user is using Word), turn
off the CapsLock.

The current process returned by the function is always "python.exe"
when I ran the code.  I also tried using win32gui.GetActiveWindow()
and it does not change either, when I switch between different
applications.

Oh, the reason I check the active application for every 0.1 second is
I don't know how to do it otherway.  Is there an event that
corresponds to the active application/window change?

Thanks again.

Well your best bet is to look at WATSUP:

   http://www.tizmoi.net/watsup/intro.html

or at pywinauto:

   http://sourceforge.net/projects/pywinauto

but I'm not convinced that what you're trying to do is
A Good Thing ;)

It's a long while since I did lowish-level Windows stuff in earnest.
I suspect you'd have to install a system message hook and look for
WM_ACTIVATE messages or something similar. Perhaps someone more
knowledgeable here can chip in...?

The concept of "current application" is a rather tricky thing to nail
down.  I typically have a dozen or more applications running all at
once.  And,when your code is running, your code *IS* the active process.

What you want to know is which application has the keyboard focus.  Tim
G's proposal is a good one: you can try installing a Windows hook and
watching for WM_ACTIVATE messages.  However, this is filled with
problems.  That's only going to give you the window handle of the
top-level parent window for the window getting focus.  It is up to you
to figure out which application that is.  You can make an educated guess
by fetching and parsing the name (GetWindowText).  However,  "always on
top" windows and modal dialogs also confuse this issue greatly, because
they grab keyboard focus without going through WM_ACTIVATE.

I've done a couple of apps that try to hook in to Windows at this level,
and it's darned tricky.  Windows was not designed for it.

I think win32gui.GetForegroundWindow is what you're looking for.

The GetForegroundWindow function returns a handle to the foreground window (the window with which the user is currently 
working).

I don't know about pywin, but some things to look at:
 GetForegroundWindow() will return the window that is currently active

It might be easier to just ask what the class name of the parent of
that window is, in that case you could just pass the HWND to
GetClassName()

AutoCAD has a specific class name (may depend on your AutoCAD version)
- Afx:00400000:8:00010011:00000000:00010199 (this is the main windows
- so you probably need to call GetParent()) - on the other hand you
may only want to set caps lock when the command line window is enabled
(class = Afx:00400000:8:00010013:00000000:00000000)

so pseudo code would be something like

# get active window
hwnd = GetForegroundWindow()
# get the class of this window
classname =  GetClassName(hwnd)
# check if it is our class...
if classname == "Afx:...." or  GetClassName(GetParent(hwnd)) == "Afx:...":
   Set caps loc

Or something like that - I have been using ctypes to do all that
windows api stuff - so I am not sure if all the methods are wrapped by
pywin32.

PyHook might be an interesting thing to look at - it allows you to
hook keyboard and mouse events at least.

Thanks again Tim G, Tim R and Mark M.  Apparently the problem is a lot
more involved than I had hoped/anticipated.  Other than WHASUP and
pywinauto, I'm also looking into AutoIt (http://www.autoitscript.com),
seems I can put something together that's close to what I want without
much difficulty. Hopefully i can find a little more time over the
weekend to explore more.

Mark, thanks for the info. about AutoCAD class names. AutoIt comes
with a tool which helps user to examine various info. about the active
window, among which is the class name.  I have been playing a bit with
PyHook and I'm trying to write a small tool for AutoCAD with it.  Not
sure if I can pull through or not.

Tim R, What do you mean by "installing" a Windows hook? Any example
available? Regarding usability, now that you asked, i'm thinking i
can't check the CapsLock for every 0.1 second, it should only be
checked when the current application is changed.  Once the user is
using AutoCAD or Word and the CapsLock is pressed by the user, the
program should not change the CapsLock status.  For AutoCAD, what
really matters is when user starts to edit TEXT/MTEXT or Block
Attribute.  So what the program really needs to wait is the windows
related to such editings popping up.

Thanks for getting the ball rolling on this! I've had our discussions
about this squirrelled away in a must-do-something-about-this folder
but...

I'm quite happy to donate by Win32 How Do I... articles
(a dozen or so, some of which are linked from the new
pyfaq site). I do add to them from time to time, but less
often than I'd like.

Fundamentally, I think any such venture has to have a clear
raison d'etre [you'll have to imagine the circumflex]. There's
not much point in its reiterating things which are Python-general:
that's what all the other Python docs are for. I see it as a way
of overcoming the still-mildly-*nix-centredness of Python use
especially in certain areas, and to reassure people in a twofold
way: Python works fine on Windows and you can do pretty much
everything you need; and if you want to do things on Windows,
Python is a great tool to use.

I'm not sure what style you're going for,
or what structure, but the sort of sections I thought would be
useful are (in no particular order):

+ Win32-specifics on various apps / modules, particularly where the 
authors are more *nix-oriented so special installation steps or even
patches are needed. Obviously this could also be fed back to the
maintainers.

+ Common Win32-specific question areas, such as: Excel, CDO, PDF, Word.
These are the sort of things I've generated my How Do I... series from,
but obviously there are loads more. I think some structure is worthwhile
here because otherwise one could just check the archives of mailing
lists etc.

+ Links to sites which provide Windows-oriented Python information,
and to some extent those which are useful for the Python programmer
even though not Python-oriented.

There's my 2.5p-worth. Happy to contribute as far as commitments
permit.

+ Hints on how to convert VB to Python (might be somewhere else already)

+ Hints on how to convert C to python (ctypes)

+ Advanced examples of how to create DLL plugins (for non Python
applications) using Pyrex (though I am not sure that documentation
exists for non windows either) (?)

+ How to build a pyd file (?)

+ Links to MSDN documentation

Feel free to say that you DON'T think the items above are a good idea also :-)

All good, I'd say, as well as some kind of summary on the
oh-no-you-can't oh-yes-you-can story on building Python
with free/non-free compilers. (Bags me not be the one
to put that together!).

One thing which isn't quite clear to me is whether things
should focus on *links* or *articles* or whatever works.
In short, I think the less philosophising and the more
action the better at this point. Let's get something going
and see how it looks.

Obvious caveat with MSDN doc links: they change faster
than I change my socks. Might be better to link to, say:

http://www.google.com/search?q=site%3Amsdn.microsoft.com+wmi

A religious discussion? I personally love Trac, but I don't know how
well it fares as a public site - due to wiki spam (though they are
working on that), and we probably don't need all the extra features
(tickets, code browser, etc)

I also don't know what you can host - but it would be cool if it was a
Python powered one like Moin Moin (though I haven't used it
extensively).

Otherwise - please pick one with a reasonable level of responsiveness
- I find that Twiki can often be a bit on the slow side.

Indeed. Although not so much as other things. It would
be politic to use a Python-driven one, and both Trac
and Moin Moin qualify. I personally prefer Trac, and
you can turn off things you don't need. I believe that
a fairly simple logon scheme (or a sophisticated one,
I suppose) deters most wiki spam.

Of course, hosting is an issue; Trac can be hosted on CGI,
but it's a tad slow.

I don't feel strongly about it though.

A Windows hook is fairly dark magic and essentially involves
adding a link into the chain of events whenever something
significant occurs within Windows -- mostly to do with the
Windows messages which are passed around between apps and
by the O/S. You really need to be sure you know what you're
doing before you launch out.

There's a useful-looking post here explaining how to
determine whether the Caps Lock is on or off:

but, frankly, except as a learning exercise, I think you're
trying to do something which is messy in the extreme and
far more fiddly than perhaps it appears from the human
perspective.

I fully expect you now to go ahead, do it easily and prove
me wrong! (In which case, we want a good write-up).

Apoligies if this goes to the wrong place - I'm new to mailing lists.  I've
done a lot of digging and tinkering, and am posting what I've found in case
it helps anybody else.

I started by py2exe'ing a script that was basically just:

execfile("test.py")

To see what did and did not work in test.py on a machine without python
installed.  test.py could be edited in notepad from any machine obviously.
I didn't expect it to work, and it didn't - I was failing with imports, so I
started sticking imports before the line execfile("test.py") which does
work.  I ended up writing a find all modules function and a 'deep import'
function for packages.  I built these into setup.py so that it would try to
import any name it found, log the ones that worked, use that log to build a
script to freeze, and ultimately freeze it.  I can't help it, I have a thing
for brute force.

Along the way, I was reading anything I could find about how import actually
works.  I also was able to define what I'm wanting to accomplish a little
better.  As far as I can tell, what an installer does in the registry is A)
Put python.exe in the search path B) Associate icons for .py and .pyc files,
C) Setup .py and .pyc files up as executable, sent to python.exe to
interperet, and D) setup the pythonpath environment variable to support
import statements.

A, B, and C are not a big deal for a developer, but they can confuse a
user.  D is a near necessity no matter who you are.

My next plan is to copy an entire python installation (files and
folders) onto a shared network drive, and write something to set up path and
pythonpath environment variables.  That way, any machine connected to that
drive should run python programs without any installation.  Making an app
launchable via 'doubleclick' will require encapsulating the setup program
and the app itself, but there are 1,001 ways to do that.

I'll report back on how this goes.  Thanks to everybody for their input.

OK, but here's the part that bothers me.  What you are describing is
essentially what an installer would do.  If you are able to do what you
suggest, then why can't you just run the installer?  What's the difference?

I cannot imagine a better summary of the situation than this.  I was
about to go into a lengthy and overly verbose (as everything I write is)
explanation of how hard this will be in practice, but I cannot top
this.  Well put.

Subject: [python-win32] Adding an "Interface" from IDL / tlb files to an
 existing win32COM-Object
Message-ID: <20070226082917.122820@gmx.net>

Hallo, 
I need help in adding an existing Interface to an object I dispatched from a COM-server via win32com in Python. 

The Code for this in VisualBasic looks like that: 

Private Obj_1 As Obj1_LIB.Impl_1 
Private mHelper As Object 
Private m_applJob As Object 
Private m_applModul As interface_Module //interface_Module is described in an IDL/TLB-File 
Private cont As Boolean 
Private c_applJob As New ApplicationJob.Job 

Set m_Obj_1 = CreateObject("Obj1_LIB.Impl_1") 
m_Obj_1.Init 

Set mHelper = CreateObject("ModulHelper.Helper") 
Set m_applJob = CreateObject("ApplicationJob.Job") 
Set m_applModul = m_applJob 

m_applModul.method1_from_appl_module 
m_applModul.method2_from_appl_module 


These methods (method1/_from_appl_module) are part of the interface loaded from interface_module and not part of the m_applJob-Object. Nevertheless, m_applModul now also supports all methods from the m_applJob-Object. 

So how can I do this in Python? 
I tried this, which didn't work: 

import win32com.client 
Obj_1 = win32com.client.Dispatch("Obj1_LIB.Impl_1") 
Obj_1.Init() 

ModulHelp = win32com.client.Dispatch("ModulHelper.Helper") 
applJob = win32com.client.Dispatch("ApplicationJob.Job") 

applJob._oleobj_.QueryInterface("{7DE9DB29-1794-4C3B-95EA-E1324B15BBE6}") ##using the uuid of the interface described in the IDL 

The error-message I receive is: 
Traceback (most recent call last): 
File "C:\PROGRA~1\python\lib\site-packages\Pythonwin\pywin\framework\scriptutils.py", line 310, in RunScript 
exec codeObject in __main__.__dict__ 
File "M:\Diagnose\Projekt EE61\ApplJob4test.py", line 655, in ? 
m_applJob=applJob._oleobj_.QueryInterface("{7DE9DB29-1794-4C3B-95EA-E1324B15BBE6}") 
com_error: (-2147467262, 'Schnittstelle nicht unterst\xfctzt', None, None) 

or, sometimes: 

Traceback (most recent call last): 
File "C:\PROGRA~1\python\lib\site-packages\Pythonwin\pywin\framework\scriptutils.py", line 310, in RunScript 
exec codeObject in __main__.__dict__ 
File "M:\Diagnose\Projekt EE61\ApplJob4test.py", line 655, in ? 
m_applJob=applJob._oleobj_.QueryInterface("{7DE9DB29-1794-4C3B-95EA-E1324B15BBE6}") 
TypeError: There is no interface object registered that supports this IID 

The second question is: 
How can I import data-types from a tlb to my python-code? Is that possible at all??? 

Thanks for your help on this!

Subject: [python-win32] DynamicProxies for VBA
In-Reply-To: <loom.20070222T121912-125@post.gmane.org>
Message-ID: <05f101c75a04$4277b960$020a0a0a@enfoldsystems.local>

I'mn afraid you need to read through the _dynamic_ implementation to see how
things work.  The COM object must list the public methods and attributes in
_public_methods_ etc before they will be exposed to COM - which is necessary
to ensure the COM semantics are implemented by Python.  VB knows only about
COM, not Python, so asking how VB can leverage __setitems__ etc doesn't make
sense - the question is what *COM* techniques you can use from VB.

I'm afraid I'm having trouble distilling a question I can answer though -
maybe you need to be more specific, possibly including code samples.

Hi!

 

I have created python object in VB.

But when I try to use this object I get Error 438: Object doesn't 

support this property or method.

 

Set py = CreateObject("Python")

py.exec ("print 'hello'")

 

Also can I get how to register the class in the windows Registry with
name "Python"

I have already created one but may have some problem.

 

Thanks and Regards.
