I would like to write a simple program so I can initiate a Shutdown (power
off), Restart, or Switch User.

Would someone point to  the API's that  I need to do this?

thanks

You can do a shutdown or reboot with win32api.ExitWindowsEx.
To switch users, use win32ts.WTSDisconnectSession.

Hi guys,

I've got this little yellow icon sitting in my system tray:
http://i7.tinypic.com/21n08ig.png

I'd like to use the windows API to somehow ask it to shutdown?  If a
system tray icon counts as a window then perhaps I could get its hwnd
and do something like:
win32gui.PostMessage(hwnd, win32con.WM_CLOSE, 0, 0)
?

FYI so far I've been closing it with kill process but the problem is
that it leaves the icon in the system tray and after a few days of
opening and closing this thing I have 1000's of icons left over in the
system tray.

Much thanks!

I would suggest killing and refreshing the system tray (or
notification area). As far as I know if you kill the process and then
move your mouse over the icon - it will disappear.

Though it sounds much better to stop that process running if you
really don't want it to run.

Look in the registry
    HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Run
    HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\RunOnce
    HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\RunOnceEx

"Startup" Start menu folder

Not sure if those help?

Ok I figured out how to do it:

Here's the code I made mostly from copying the examples.  If anyone
could tell me how the code works, that would still be appriciated, for
example why/how do I need this function _MyCallback?

-Greg

My code:

import sys
import win32process, win32api, win32pdhutil, win32con, win32security
import win32event, msvcrt, win32gui

def get_all_windows():
    """Returns dict with window desc and hwnd,
    don't ask me how it works!"""
    def _MyCallback( hwnd, extra ):
        """Helper function for above??"""
        hwnds, classes = extra
        hwnds.append(hwnd)
        classes[win32gui.GetClassName(hwnd)] = hwnd
    windows = []
    classes = {}
    win32gui.EnumWindows(_MyCallback, (windows, classes))
    return classes

def request_windows_to_close(list_window_descs_to_close):
    """Send me a list of stuff to close such as:
stuff_to_close=['OP15_OmniPage_Agent_Class',]"""
    classes=get_all_windows()
    for windesc_to_close in list_window_descs_to_close:
        if classes.has_key(windesc_to_close):
            win32gui.PostMessage(classes[windesc_to_close],
win32con.WM_CLOSE, 0, 0)
            print 'requested closure with', windesc_to_close
        else:
            print 'Did not find a window desc. as',windesc_to_close

Does mousing over the icon not make it disappear after it's killed?  If you can get the handle to the process, say via EnumWindows, you can user the TerminateProcess API call.

Message-ID: <67dcd18b0608020416m37406313ofda268b7651c6402@mail.gmail.com>

Hi all!

I've been trying to solve a small but disturbing problem with
win32com, but I can't.
It's the "OLE Server Busy" problem [1]:
"If you call a method on a COM server from an MFC COM client
application and if the method takes a long time to process and return
back, you won't be able to do anything on the client application and
the OLE Server Busy dialog box pops up..."

The link explains how to solve it. But it's not that straight forward
in python. They suggest using Afx* functions. So I tried putting that
on a DLL and then calling them from python using pyrex. But it didn't
work out. The functions are called, but the program crashes when
trying to access a member of the Filter. And adding a DLL only makes
it more complex. There should be a simple-clean way to do that.

Anyone had this problem before? Anyone figured out a way to fix it?

Thanks in advance,
Diogo

Unless you are using the win32ui module, its unlikely you qualify as an "MFC
COM client".

It also casually mentions at the bottom:

| Another way to suppress the server busy dialog box is to use
| OleInitialize and OleUninitialize instead of AfxOleInit in your
| application.

which are easy to call.

Yeah - things aren't going to work that well if MFC isn't correctly
initialized.

Try and ensure your threads are all initialized for free-threading (setting
sys.coinit_flags=0 before importing win32com/pythoncom will ensure that is
true for the main thread), and that all threads are running message loops.

Subject: [python-win32] Dispatches With Events on COM Object
Message-ID: <44D098E9.1030209@cenix-bioscience.com>

Hello,

          I am trying to use PythonCOM to interact with a provided 
proprietary COM object.  The Object consists of three dispatch interfaces:

IApplication
IApplicationEvents
IDocumentEvents

    This can be accessed using the CoBaseClass by ProgID 
'OpalControl.Applcation' - so far so good.  The first thing I do is to 
run the following code:

import win32com.client
import time

objCybio = win32com.client.Dispatch('OpalControl.Application', CybioEvents)
objCybio.ConfigFile = r"C:\CyBio Software\Config\opalctrl.ini"
objCybio.Config = "CyBi-Well"
objCybio.visible = True
objCybio.OpenDocument(r'C:\testscript.igl', True)
time.sleep(2)
objCybio.CloseDocument(r'C:\testscript.igl', True)
objCybio = None

    This works fine and it does what I expect, so the next thing to do 
is to try and write something to get the events:

import win32com.client
import time
import win32com.client.gencache

class CybioEvents(object):   
    def __init__(self):
        super(CybioEvents, self).__init__()

    def onCommand(pstrTitle, pstrParam):
        print 'OnCommand\n', pstrTitle,'\n', pstrParam

objCybio = win32com.client.DispatchWithEvents('OpalControl.Application', 
CybioEvents)
objCybio.ConfigFile = r"C:\CyBio Software\Config\opalctrl.ini"
objCybio.Config = "CyBi-Well"
objCybio.visible = True
objCybio.OpenDocument(r'C:\testscript.igl', True)
time.sleep(2)
objCybio.CloseDocument(r'C:\testscript.igl', True)
objCybio = None

  When I run this, I get the following error:

Traceback (most recent call last):
  File "C:\Program 
Files\Python24\Lib\site-packages\pythonwin\pywin\framework\scriptutils.py", 
line 310, in RunScript
    exec codeObject in __main__.__dict__
  File "C:\Documents and Settings\benn\Desktop\cybio test.py", line 9, in ?
    objCybio = 
win32com.client.DispatchWithEvents("OpalControl.Application", CybioEvents)
  File "C:\Program 
Files\Python24\Lib\site-packages\win32com\client\__init__.py", line 254, 
in DispatchWithEvents
    raise TypeError, "This COM object can not automate the makepy 
process - please run makepy manually for this object"
TypeError: This COM object can not automate the makepy process - please 
run makepy manually for this object

    So no probs, using the makepy utility in PythonWin (I'll automate 
this later ;-) )  I generate the required stubs and a file does appear 
which seems to be OK (contains the correct GUIDs and interfaces and so 
on).    Running this again, I get :

Traceback (most recent call last):
  File "C:\Program 
Files\Python24\Lib\site-packages\pythonwin\pywin\framework\scriptutils.py", 
line 310, in RunScript
    exec codeObject in __main__.__dict__
  File "C:\Documents and Settings\benn\Desktop\cybio test.py", line 9, in ?
    objCybio = 
win32com.client.DispatchWithEvents("OpalControl.Application", CybioEvents)
  File "C:\Program 
Files\Python24\Lib\site-packages\win32com\client\__init__.py", line 254, 
in DispatchWithEvents
    raise TypeError, "This COM object can not automate the makepy 
process - please run makepy manually for this object"
TypeError: This COM object can not automate the makepy process - please 
run makepy manually for this object

    Basically the same as above, I've checked this COM object out with 
VB and it works fine - no probs.  In addition looking at the stub file 
in the cache in gen_py, the class has not been compiled to a pyc file 
(I'm assuming that it should be here) so it seems like it is not even 
finding this - although that is a guess.

  I've also tried using the GUID to get hold of the CoBaseClass using 
the GUID but I get the same error, unfortunately I cannot give you the 
COM object as it is dongle protected and therefore will not run.  I can 
attach the generated file from makepy but I won't do that as yet because 
it is relatively big.

  Can anyone shed any light as to how I can track down this problem?

  Thanks in advance for your help.

Cheers,

Neil

The EnumWindows API runs through the system's linked list of all
top-level windows.  For every window it finds, it calls a function that
you provide.  If you know C++, it's a lot like the for_each function in
STL.  _MyCallback is the function that gets called, once for every
top-level window.  It is passed the handle of each window in turn, along
with a "context" parameter that you provide.  In your example, the
context parameter is a tuple that will be used to keep track of all of
the windows and window classes that were found.

So, when "get_all_windows" finishes, it returns a dictionary that
contains one entry for every window class.  request_windows_to_close
then checks to see if the class(es) you requested are present in the
dictionary, and if they are, it sends them a WM_CLOSE message.

This code is not actually correct.  There can be many windows for a
given window class, but your get_all_windows function will only return
the last one found for each class.  A better implementation of
_MyCallback would be:

    def _MyCallback( hwnd, extra ):
        hwnds, classes = extra
        hwnds.append(hwnd)
        classn = win32gui.GetClassName(hwnd)
        if not classn in classes:
            classes[classn] = []
        classes[classn].append( hwnd )

Then request_windows_to_close becomes:

    for windesc_to_close in list_window_descs_to_close:
        if windesc_to_close in classes:
            for hwnd in classes[windesc_to_close]:
                win32gui.PostMessage( hwnd, win32con, WM_CLOSE, 0, 0 )
                ...

The problem will be that the object itself doesn't supply the typeinfo
necessary to associate the object with the makepy generated class.  It
should however be possible for you to manually extract a suitable object
though.

What you need is something like:

from win32com.client import gencache
mod = gencache.EnsureModule(...) # use 'makepy -i' to see the params
ob = mod.Application()
objCybio = win32com.client.DispatchWithEvents(ob, CybioEvents)

'mod' will be a reference to the makepy generated module.  Assuming this
module defines a class called 'Application', 'ob' should be an instance of
the COM object, but with makepy support.  Passing this object to
DispatchWithEvents instead of the CLSID means the type info is available.

Hope this helps,

Mark

Hello,

          Hmm the type info looks like an issue, the new code is now:

mod = gencache.EnsureModule('{A4818FD5-6479-11D4-8452-00104B92DD56}', 0, 
1, 0)
print dir(mod)
ob = mod.Application
objCybio = win32com.client.DispatchWithEvents(ob, CybioEvents)

--
This now gives me the following error:

Traceback (most recent call last):

    Interestingly, the printout of dir(mod) gives me:

'makepy_version', 'python_version', 'pythoncom', 'win32com']

    For completeness, I've attached the generated file from makepy (the 
above test was done without this present).  I've done some playing 
around, if I do a simlpe dispatch (without events) the makepy file does 
not get compiled to a pyc but the __init__ does.

    Any thoughts?

    Thanks for any and all help/advice.

Cheers,

Neil

Much of the win32 stuff fairly thinly wraps the Windows API, so MSDN
is often a good place to look. For example:

Thanks Simon that worked!

FYI, future readers the answer is that those two parameters are
message specific and for wm_close they don't do anything.  Probably
just search for your message on MSDN to find out what the parameters
are for other messages:

WM_CLOSE Notification

The WM_CLOSE message is sent as a signal that a window or an
application should terminate.

A window receives this message through its WindowProc function.

Syntax

WM_CLOSE

    WPARAM wParam
    LPARAM lParam;

Parameters

    wParam
        This parameter is not used.
    lParam
        This parameter is not used.

Return Value

    If an application processes this message, it should return zero.

Try adding parens after that line - currently 'ob' is the class, where you
want an instance of the class.

ob = mod.Application()

That may get closer.

Message-ID: <6.2.3.4.2.20060803182830.058e2c28@blue-cove.com>

I have been trying to use sleep() and kernel32.QueryPerformanceCounter together; I want to delay until a particular tick without trying up the CPU badly. 
However, while time.sleep(.001) relieves the CPU, it has wildly unpredictable delay, and sleep(.0001) delays almost nothing at all! (I'm watching the parallel port on a scope).
If I use a while and just count ticks with QueryPerformanceCounter(), it is very stable and as desired - but it uses 100% CPU.

RTAI LINUX has a nanosleep() function that does it all very nicely on our Debian install, is there a parallel in Win32?
The MS Sleep() function is in integer milliseconds...

sample code:
___________________________________________________________________

TTLHighDur = ticksPerMs/2
currTicksPerRot = fsTicksPerRot
qPC(byref(c0))
tick0 = c0.value # initial count
nextTTL = tick0
## make a TTLOUT 
endTick = tick0+pF* 15 #seconds
rotN = 0

while(True):
    nextTTL = currTicksPerRot+nextTTL
    sleep(.0001)# sleep for most of the time needed
    while(True): #loop until the exact tick
        qPC(byref(c1))
        if c1.value>nextTTL: break
    out(0x378, 0xFF) #set all bits high
    while(True): #loop until the exact tick
        qPC(byref(c1))
        if c1.value>nextTTL+TTLHighDur: break
    out(0x378, 0x00) #set all bits low
    rotN += 1
    
    if c1.value>endTick: break

    Although I'm not sure if there are any other solutions in the python

I'm not sure if this really works, but you could try:
- Raise your thread/process's priority using SetPriorityClass or 
SetThreadPriority. This is to minimize the (unpredictable) delay of sleep()
- Keep your qPC loop, but insert a sleep(0) call, this would free the CPU.

I'm not using the win32ui. And this makes me wonder I would get this box.

The program was using CoInitialize() only. Now it uses OleInitialize().
The "busy message" doesn't appear always, and with OleInitialize it
stopped appering in my computer. But while running in another computer
it still appears.

BTW, there's no OleUninitialize. Should I use the Co one?

Thanks for the help,

I do launch the module with CreateProcess with RealTimePriority - it 
does stabilize things a bit

>- Keep your qPC loop, but insert a sleep(0) call, this would free the CPU.

Does 0 have a special meaning vs. .0000001 for example? I'll give it a try.
The desired total delay is about .0056s, so I'd like to sleep() for 
~.004 and then wake up and catch the exact tick. For some reason, 
sleep(.001) actually adds up to a good bit more, like .004, and 
sleep(.0001) collapses to ~statement execution time, like 10us! 
That's why if I use .0001 the CPU is still 100% loaded; with .001 it 
drops to near zero, but, the timing is way off.
I'l do an example code to demonstrate, and see if others get the same 
responses.

I'm wondering if sleep() uses the 8254 or RTC timers instead of the 
TSC counter or APIC timer(?)

I did see an interesting point about RTAI as well " Also, one should 
note that nanosleep() is a busy wait in the kernel when the request 
to sleep is for an amount of two milliseconds or less. Therefore, a 
busy wait would not simulate interrupt response time as well as a 
true sleep. ", so LINUX does not have a true short sleep() either...

http://www.rtems.com/ml/rtems-users/2004/march/msg00067.html
has a good discussion as well that I need to look into.

Thanks,
Ray

No.  Windows simply has no mechanism for doing sub-millisecond sleeps. 
The default scheduling interval in XP is 10 milliseconds.  You can't get
an interrupt more granular than that, even in kernel mode.  It is
possible to change the scheduling interval to 1 millisecond by using
timeBeginTime, although performance suffers.

It is possible to use QueryPerformanceCounter to do a spin-stall, but
you are essentially in an infinite loop.  ALSO remember that you are
still sharing the CPU with other processes.  If another process decides
it wants to hog the CPU for its whole time slice, you'll lose 10
milliseconds.  If a driver decides it needs to do a thermal
recalibration on your disk drive and stalls for 5 milliseconds, you'll
lose 5 milliseconds.

Remember that RTAI LINUX is a real-time operating system designed for
deterministic processing.  Windows most definitely is not.

In the attached test code, I get - for test in  [0, .1, .01, .001, .00001] seconds 

    # 2.9us hi 5.2us low,

Intestingly, if I un-comment the

then the processor usage drops by ~11 per cent.

If anyone has comments on these sleep() results, please enlighten me as to why.
Ideally, on how to implement a shorter sleep() (wrap/weave C?) and still relieve the CPU...

I see a timeBeginPeriod (?):
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/multimed/htm/_win32_timegettime.asp
used with timeGetTime, normally...
"Windows NT/2000: The default precision of the timeGetTime function can be five milliseconds or more, depending on the machine. You can use the <http://msdn.microsoft.com/library/en-us/multimed/htm/_win32_timebeginperiod.asp>timeBeginPeriod and <http://msdn.microsoft.com/library/en-us/multimed/htm/_win32_timeendperiod.asp>timeEndPeriod functions to increase the precision of timeGetTime. If you do so, the minimum difference between successive values returned by timeGetTime can be as large as the minimum period value set using timeBeginPeriod and timeEndPeriod. Use the QueryPerformanceCounter and QueryPerformanceFrequency functions to measure short time intervals at a high resolution, 

Windows 95: The default precision of the timeGetTime function is 1 millisecond. In other words, the timeGetTime function can return successive values that differ by just 1 millisecond. This is true no matter what calls have been made to the timeBeginPeriod and timeEndPeriod functions. "

I'll fiddle with these later.

What surprises you?  The Win32 Sleep() function takes integer
milliseconds.  Thus, .00001 will round to 0, which says "give up the CPU
only if a higher-priority task is waiting.".

The default scheduling interval on your system is 16ms.  Some Windows
systems use that, some use 10ms; it depends on the HAL.  Windows only
checks for timer expiration when its scheduling runs, and the scheduler
doesn't run any more often than that.  You can reduce that to 1ms by
using timeBeginPeriod (I said timeBeginTime before; that was wrong), but
it will cost overall system performance, because you're getting
interrupts 16x as often.

Then, it will just have to be seen whether a faster scheduler is
worse than tying up one half of a dual core CPU with a thread just doing 
whiles and checking for messages.
A test on Win9x might be interesting too, to use its 1ms schedule.

Thanks again,

That surprises me, and sadly I can't think of a reasonable COM object I can
use to help test this with.  Note the offending code in __init__.py:

  if not disp.__class__.__dict__.get("CLSID"): # Eeek - no makepy support -
try and build it.
    try:
      ...
    except pythoncom.com_error:
      raise TypeError, "This COM object can not automate the makepy
process - please run makepy manually for this object"

I'm expecting that first if statement to cause the entire block to be
skipped.  Indeed, 'CLSID' is one of the attributes in that list printed
above.  You may like to try and see if you can workout why we are entering
that block.

Cheers,

Mark

Subject: [python-win32] Need help with converting a simple Excel macro
Message-ID: <20060805025522.15460.qmail@web51409.mail.yahoo.com>

Hi list,

I have a need to copy 3 rows of data from the top of
my Excel spreadsheet to another location.  I would
have throught that this should be very straightforward
since I've done a fair amount of Excel/Python
programming.  Unforturnately, I am stuck on this one.

The VB Macro says I need to:

    Range("1:1,2:2,3:3").Select
    Range("A3").Activate
    Selection.Copy
    Rows("20:20").Select
    ActiveSheet.Paste

So, I figure the Python code would be something like:
			
<xlApp determined already>
1) xlSheet=xlApp.ActiveWorkbook.ActiveSheet
2) xlSel=xlSheet.Range("1:1,2:2,3:3").Select()
3) #xlSel=xlSheet.Range("A3").Activate()
4) xlSel.Copy()
5) xlSheet.Rows("20:20").Select()
6) xlSheet.Paste()

Unfortunately, this doesn't work.  After line 2, xlSel
becomes "True" - not a "Selection" and so the code
fails at line 4).  I am not sure why I have to do the
"Activate" on line 3 but it didn't matter, the code
still fails at line 4.


What am I doing wrong?

Any help is greatly appreciated.

Regards,

In this line, the result of the Select call is
bound to xlSel, rather than the Range object you need.
Try these 2 lines instead:

xlSel=xlSheet.Range("1:1,2:2,3:3")
xlSel.Select()

Thanks for the help, Roger.  Yes, that works.  I just
have to remember that:

xlSel=xlSheet.Range("1:1,2:2,3:3").Select()

is *NOT* the same as:

xlSel=xlSheet.Range("1:1,2:2,3:3")
xlSel.Select()

Thanks again.

My employer would like an Access database updated.
It has been made partly by hand before, but I thought it should be
automated, as 99% of the relevant information is available by looking
at the file system and parsing some text files.
In the past week this has led me to learn something about python
dictionaries, tuples, lists, classes, expected syntax, WinPython (got
that book here, ya :), and I'm at the point where I've created a new
database with nice relations between the tables and all information
available.

Except the preview pictures.

Now, other db's can take binary things beyond 1kb without coughing,
but he needs it to be Access for the customers' sake. So, ADO and
creation of an embedded OLE object it is, I'm thinking.
Visual Basic guides inherits the OLE object from a base class and uses
the creation method from it.
So my question is.. where do I get this method and object from in
WinPython? It is probably simple, but I can't find it :]

I use Python 2.4, WinPython, and have run makepy on DAO and ADO
libraries. I did -not- attempt to parse makepy's generated files
beyond skimming it :]

adoConn.Execute("DROP TABLE Preview")
adoConn.Execute("CREATE TABLE Preview (SceneId int, Preview OLEObject)")

adoRS.Open("[Preview]",adoConn, 1, 3)  # 1=adOpenKeyset, 3=adLockOptimistic
adoRS.AddNew()
adoRS.Fields("SceneId").Value=1
adoRS.Fields("Preview").Value=**** What is expected here? *****

Hello,

          Thanks for your reply, I put logging onto the screen and here 
is what I found:

    * The call to Dispatch happens
    * The __wrapDispatch is called with an object for dispatch but the
      username is None
    * The getTypeInfo method throws an pywintypes.com_error which has
      the message of (-2147467263, 'Not implemented', None, None)
    * The dynamic dispatch method is called which returns an instance of
      COMObject
    * the __class__.__dict__ for this has the following key/value pairs

0 = _wrap_dispatch_
1 = __module__
2 = __doc__

    Therefore there is no CLSID for the object which causes the makepy 
message to appear.  I've printed out the return from the dynamic 
dispatch call:

DISPATCH PRINT
<COMObject <unknown>>
DIR DISPATCH PRINT
['_ApplyTypes_', '_FlagAsMethod', '_LazyAddAttr_', '_NewEnum', 
'_Release_', '__A
ttrToID__', '__LazyMap__', '__call__', '__cmp__', '__doc__',

'_print_details_
', '_proc_', '_unicode_to_string_', '_username_', '_wrap_dispatch_']
DISPATCH MAP
0 = _wrap_dispatch_
1 = __module__
2 = __doc__
   
    Is there anything there which could provide a clue?

Apparently access uses some kind of undocumented byte stream format

There's some code in this article

Hi!

Some more details about the server busy dialog box.

This program, that I'm working with, calls MakeActiveXClass(wxPython),
which calls pywin.mfc.CreateControl, which calls
win32ui.CreateControl. If I connect to a slow COM server just _before_
the call to win32ui.CreateControl, then everything is fine, no busy
message. But after the Control is created, it seems that the program
gets in an "incorrect" state, i.e, whenever I call a slow COM server,
_after_ CreateControl has been called, the busy message box will
appears.

is there perhaps any initialization that I may have forgotten, or any
other ideas?

Thanks a lot,
Diogo

I can throw you a new win32uiole module with the functions referenced in the
knowledge base article, but apart from trying to fiddle with the main
thread's thread-state (search for 'sys.coinit_flags'), I can't offer much
more help...

It is that last step where things go wrong it seems.  If the object is
already a makepy wrapped object, we shouldn't call GetTypeInfo - the object
should just be used as-is.  We might need a similar check for a CLSID
attribute there (or better, a function eg, gencache.IsGeneratedObject() that
abstracts that implementation detail).  I'm afraid I'm out of time for today
though...

It's an ugly but well-known limitation: the buffer passed to
CreateFileDialog is big, but not big enough.  When you select more files
than will fit, the API returns an error, and the wrapper returns that
error instead of reallocating and retrying.

You can call win32gui.CommDlgExtendedError() to find
the reason why it failed.  If the buffer size is actually the
problem, it will return winerror.FNERR_BUFFERTOOSMALL
(12291).

win32gui.GetOpenFileNameW creates the same type of dialog,
and you can use the MaxFile argument to specify a large buffer
size if needed.

But how can one detect that?
DoModal() returns 2 (IDCANCEL) in this case, how can be distinguished 
from the user pressing the Cancel button?

Hi list!

It follows how the "OLE Server Busy" problem can be solved.

The problem is this:
"If you call a method on a COM server from an MFC COM client
application and if the method takes a long time to process and return
back, you won't be able to do anything on the client application and
the OLE Server Busy dialog box pops up..." [1]

To solve that, Mark modified the win32uiole, adding the necessary functions.

Something like the following should be enough:

import win32ui
import win32uiole

if hasattr(win32uiole,'SetMessagePendingDelay'):
    win32uiole.AfxOleInit()
    win32uiole.SetMessagePendingDelay(aBigDelay);
    win32uiole.EnableNotRespondingDialog(False);
    win32uiole.EnableBusyDialog(False);

Note that these functions are not yet avaiable in release 209.

Thanks for the help!

Regards,
Diogo

Hi!

I would like to connect to a dcom interface on windows from Plone

For Linux there exists an dcom-implementation, that probably is not really
cheap

Does anyone know something else? Perhaps especially for python and /

Allow me to apologize to pywin32.  The problem is not in the pywin32
wrapper, the problem is in MFC.  Pywin32 uses the MFC CFileDialog class,
and that class has a hard-coded 256-byte buffer for the file names. 
Pywin32 cannot "reallocate and retry"; the interface is simply not exposed.

Roger Upole's advice is the best: use win32gui.GetOpenFileNameW.  It's
not quite as friendly, but it doesn't have the same limitation.

Message-ID: <8C4B4388BC176244B5F36267D14B0BC9011FC3C9@exchange.wsdomain.lan>

I am new to this group, but I'm hoping someone could offer some advice
as to a complicated issue I am having.

I have created a (multithreaded) Python application that performs
asynchronous queries. Unfortunately, I'm having a very difficult time
setting it up as a service.

It should run as follows:

1) A remote server starts the service
2) while the service is running, it performs its asynchronous
lookups--something like:

while 1:

ASYNCH_QUERY()

time.sleep(30)
else:

sys.exit()

I have taken a look at the pipeTestServiceClient.py and
pipeTestService.py examples from win32all build 209, but I couldn't
figure out how to adapt it to my own code, since nothing needs to be
echoed back to the "invoking" server. Does anyone have any ideas?


Thanking you in advance,

CAN

Have you tried the MSDN help on this COM Module? Mmmmm...actually after
looking through the docs, maybe its not a whole lot of help. I see a lot of
"Not Currently Supported" statements. Well, here's the link anyway in case
there's something there:

Subject: [python-win32] Variant ByRef 2D array returned as 1D array
Message-ID: <a41467040608160611g4b4c67femfb94f21a9f32ea66@mail.gmail.com>

I'm working with a COM module that is returning a 2D array as a
VARIANT BYREF. The 2D array is 30x8 (with each entry being 1 byte)
When the data is returned I'm getting a buffer of length 30. This
tells me that win32com only sees 1D of the array (documentation states
that the buffer is expected for variants-byref with entries of 1
byte). Any ideas on why win32com doesn't see that there is really an
array of arrays?

The author of the code tests with VB so it seems to be working there,
but not with Python. Here's a rough code snippet from the com module
on how it is building the variant that needs to be returned.

long lDimension[2] = {0,0};
SAFEARRAY *dataBuffer = variantReturn.parray;

psaDataBuffer->rgsabound[0].cElements // this is programmed to 8 somewhere
psaDataBuffer->rgsabound[1].cElements // this is programmed to 30 somewhere

// For each field of the entry
for(int outerindex=0; outerindex<30; outerindex++){
    lDimension[0] = outerindex;
    for(int innerindex=0; innerindex<8; innerindex++){
        lDimension[1] = innerindex
        SafeArrayPutElement(dataBuffer,lDimension,
&data[outerindex][innerindex])
        }
}
// variantReturn is the actuall return that I'm trying to get.

Any ideas?

Thanks,
Kevin

I think the problem is just the MSN documentation...The pythoncom
stuff is working as expected. To make things a little easier, I
recommend using the MakePy in pythonwin. It will create a .py file
that helps a small amount when trying to figure out what functions and
such you need to call. I renamed the output file to msn.py and ran the
following:

import msn
mapp = msn.Messenger()
person = mapp.GetContact("someoe at emai.com",mapp.MyServiceId)
imsg = b.InstanteMessage(person)

No clue how to send a message from here...I recommend just googling on
these function names and you'll end up seeing some VB code, but the
same function calls usually work pretty similarly in python

If your application works as expected before converting to a service, there
should be no problem getting it working as a service.  At the most basic
level, your service's main thread can do nothing more than interact with the
service control manager, and your application code should be able to run in
its own thread, quite independent of the service interactions.  The only
minor complication will be to have the main service thread communicate
service shutdown to your app code.

Can you be more specific about what problems you are having?

  Subject: [python-win32] Multithreaded Service


  I am new to this group, but I'm hoping someone could offer some advice as
to a complicated issue I am having.

  I have created a (multithreaded) Python application that performs
asynchronous queries. Unfortunately, I'm having a very difficult time
setting it up as a service.

  It should run as follows:

  1) A remote server starts the service
  2) while the service is running, it performs its asynchronous
lookups--something like:

  while 1:

  ASYNCH_QUERY()

  time.sleep(30)
  else:

  sys.exit()

  I have taken a look at the pipeTestServiceClient.py and pipeTestService.py
examples from win32all build 209, but I couldn't figure out how to adapt it
to my own code, since nothing needs to be echoed back to the "invoking"
server. Does anyone have any ideas?


  Thanking you in advance,

  CAN

If the type of one dimension is VT_UI8, then pythoncom will treat that as a
'byte buffer', so will return a string - in which case you will simply need
to pretend the string is actually an array of bytes!  Otherwise you are
probably going to need to help create a test case so I can see exactly what
is going on - what language is this object implemented in, and is the source
available?  We have test COM objects written in VB and C, so creating a test
case shouldn't be too hard.

Cheers,

Mark

win32com is definitely treating it as a string (or byte buffer), but I
would have expected to get a byte buffer with the data for ALL the
elements. For example the array being returned should be 30x8 array,
but i get a string with a length of 30 instead of a string of length
30*8. Does the pythoncom know to traverse both arrays and convert in
to one big buffer? Seems like I'm getting only the first element of
each entry in the 30x8 array.  Juduging from your statement I think
the fact that its a buffer (instead of a 2D list) is ok, but I should
be getting a buffer of lenghth = 30x8 instead of just 30.

Thanks for the offer of help, I'll fight some guys on my end to reduce
the code down and see what I get :) The problem occurs both on the
read and write. In other words: I can't seem to write a 2D array back
in to the COM module by refrence either, so hopefully the writers of
the COM can also tell me what data they are getting versus what they
are expecting to help pinpoint the problem.

Message-ID: <C180F101-E42D-4EAA-8EEE-39EE2435006A@dcs.qmul.ac.uk>

Hi,

since python 2.3.4 and wxPython 0.6 it was possible to render rtf in  
wxTextCtr like

class RTFWindow(wx.TextCtrl):

   def __init__ (self,parent):
     wx.TextCtrl.__init__(self,parent,style = wx.TE_MULTILINE |  
wx.TE_RICH | wx.TE_READONLY)

...
win = RTFWindow(None)
win.rtfSubWin.LoadFile(path)

and it would render RTF correctly.

However, since then, I only get the source of the RTF as plain  
text...  any ideas why this is?

Is there any way to easily convert the RTF into HTML in python? Then  
I could use wx.HTML...

thanks for advice
Chris

Hi list,

I have a Python script that pops up Excel, fill it,
and then continue.  If the user clicks on my Python
side to  close Excel (via a call to the Quit()
function), then I can reopen it later via another
dispatch call and so forth.

However, if the user close Excel from the Excel side,
next time Python side starts Excel again, the Excel
display area (the area where the spreadsheet cells
goes) is screwed up.  The rest of things works fine
(like the menu bar and so forth) - but the spreadsheet
display area is useless.

Is there any cure to this?

Thanks,

I have dealt with this a lot. The "cure" is somewhere in Redmond, but 
probably too low a priority for Microsoft. Sigh. The only workaround I 
know is to kill the excel process.

Interesting description.  Sounds similar to a non-MS app I automate
which does something similar.  If closed from Python everything works
fine; however, if user closes app before Python the next time it's
launched it opens hidden and user can't see it at all.  The only partial
work around I've found is to use a certain routine in that app to detect
the condition and enum the toplevel windows to find and kill the pid of
the hidden app.  Sounds awfully similar.  Is the Excel issue definitely
a MS one I wonder...just thinking out loud.

You may be better off trying the various wx mailing lists - not many wx
people hang out here (I guess as most wx users are targetting more than
Windows!)

I think the problem is that there is not a lexer for RTF in the TextCtrl family.
But:

For wx 2.7...
http://www.wxwidgets.org/wiki/index.php/Development:_wxRichTextEditor
http://wiki.wxwidgets.org/docbrowse.cgi/wxwin_wxrichtextctrl.html

I think you can use this for now:

You might be able to use win32com.client.DispatchEx to start Excel.
This should make sure you always get a new Excel process,
rather than returning a reference to the one that the user closed.

Hi!

*sorry for my bad english*

A COM server, in PyWin32, is a class.
When this class has a "attribut de class" (sorry it's in french ; english = 
attr of class?) , and if this attr of class is also in the _public_attrs_ 
list, it is changed, like a attr of instance.

If I open twice the COM server, in the same application, when the first 
instance change the attr of class, the change is not visible from the second 
instance.

Am I correct, or am I fail?

@-salutations

Hi!

A little stunt :  in COM server (with pywin32), atexit is not interesting.

Then, look, in the class-serverCOM, the method   __del__(self):
When you close the COM-server, or when you exit the application who called 
the COM-server, the method is called.

And...   "le tour est jou?"  (french sentence)

Yeah, Python is never 'finalized' when it is loaded for use by a COM object.

This should be reliable - assuming that the program *using* the COM object
always destroys the COM object correctly.  However, it would be possible to
write a Python program that used the COM object that did *not* cleanup the
object, so would not cause this method to be executed...

When a COM attribute is set, Python does the equivalent of:

  setattr(instance, 'attr', 'value')

So - even if you have:

  class Foo:
    attr = 'original value'

If 'Foo' was a COM object, it is equivalent to:

  f1 = Foo()
  f2 = Foo()

  setattr(f1, 'attr', 'new value')

The way Python works, this means that 'f1' now has an *instance* attribute
'attr' - the setattr() did *not* change the class attribute - so 'f2' will
still return 'original value' when queried for that attribute.

Hope this helps,

Mark

Hey all I am learning Python and having a fun time doing so.  I have a question for y'all, it has to do with active directory.

I want to get the last login for a computer from Active Directory.  I am using the active_directory module and here is my code.

[START]

import active_directory

computer = active_directory.root()
for cpu in computer.search ("cn='Computer_Name'"): 
    print cpu.samAccountName				?--- Works find
    print cpu.operatingSystem				?--- Works find
    print cpu.lastLogon					?--- Getting Error

[END]


I get an error that I am not sure what to do with, the error is TypeError: coercing to Unicode: need string or buffer, instance found in my line 
Do I have to change the output to meet Unicode formation?

Subject: [python-win32] running windows 'start' cmd using spawnl
Message-ID: <44EC9D68.3040306@gmail.com>

Hi,

I need to start a program in a new cmd-window. To do this I need to 
execute: start [command]
With os.system this is straight-forward.
But I need to do it with spawnl and P_NOWAIT. I.e, asynchronously.
The problem is that I need to know the path where start resides,
which I'm unable to find.

Does anyone know where this command is located, or an alternative way of 
doing what I want?

There is no path to start, it's a built-in shell cmd.  If you want to start it asynchronously just use start's background method.

os.system("start /B command")

I use this all the time to launch things in the background and continue on my merry way.

I get back an ADLargeInteger for this property,
which actually represents a FILETIME.
What does type(cpu.lastLogon) show?

os.startfile is async.  You could also use win32api.ShellExecute
directly (os.startfile call this function under the covers)  or
win32process.CreateProcess if you need more flexibility.

I have a "fairly" simple test script that appears to exhibit a memory 
leak when using ADO to insert rows in a SQL Server database via a 
persistent connection.

Memory requirements monotonically increase with time (apparently in 4k 
increments).

I'm using python 2.4.1,  win32com (pywin32 build 209), and MS Windows XP 
with all current updates.

Has anyone else seen this behavior?

Any thoughts about where the problem may be?

Thanks,
-- jv

P.S.
Earlier tests showed that:

    * simply maintaining a persistent connection (for 24 hours) is not
      the cause
    * maintaining an active connection and the insert command object are
      not the cause

There are a large number of Google hits for "ado memory leak".  Few of
them will probably help you, but they might provide some clues.

One good suggestion is to use a tool like PerfMon to monitor your memory
use in a more detailed way; Task Manager sometimes takes shortcuts such
that the memory use isn't really what it says it is.

Thanks Tim.

Prior to posting, I did try Google (should have mentioned that) and 
found a fair amount of anecdotal postings but nothing as concrete as I 
had hoped for.  Perhaps I should give it another try though; I may have 
missed something.

I did not think to try PerfMon so I will give that a look as I am not 
familiar with it.  Despite any shortcuts Task Manager employs, there 
clearly is a memory leak that is significant over a period of days and 
the memory requirement of the application steadily increases.

Does the script print anything, and are you running from pythonwin or
python.exe ?  Pythonwin accumulates output indefinitely, whereas
python.exe eventually starts discarding it once you exceed the output
buffer size of the console window.

Could you post the script that demonstrates the problem ?
I'll try to set it up to run for a while in debug mode to see if
any problems show up with python refcounts or COM interface
refcounts.

Hi,

I'm an engineer from France and I use PythonWin very often. I Have one
question please : I'd like to run a function from a library included in the
"Tools=>COM Browser=>Registered Type Librairies" menu. This library is
called "Bibioth?que de pilotage de Scandiag" and I'd like to run from this
library the function called "Telechargement" from "ISScandiagOCX".
Just below is the source code in Visual basic just as an example so that
you can get more easily what I try to explain you :

Private Sub CommandButton1_Click()
Dim MonObjet As ScandiagOCX
Dim result As Integer
Set MonObjet = New ScandiagOCX
result = MonObjet.Telechargement("C:\Scandiag\Files\edc16.can", 1, 1, 1)
Set MonObjet = Nothing
End Sub
Actually, I'd like to do the same in python.

I tried already :

import win32com.client
ob = win32com.client.Dispatch("The.ProgID")
ob.Telechargement()

But actually, I don't know which arguments I need to use with the dispatch
command.
Therefore, what I want you to explain me please is how to determine the
"Prog ID". Is it a number, a string??


Thanks a lot in advance for your help,

Subject: [python-win32] Memory Consumption when running Python COM Script
Message-ID: <bab5abcd0608250118p4ec4ee71xd8b33202553f51bd@mail.gmail.com>

Hi,

We are having performance problems when running python COM Scripts. The app
starts it own internal scripting engine and if we use VBScript, everything
is fine. If we use PythonScript, the app consumes large amounts of memory
(up to 3 GB) and the crashes because it runs out of memory.

This is the (simplified) PythonScript:
=====================================
counter = 0
for AnObject in OurApp.Array():
    counter = counter + AnObject.Value()
=====================================

The corresponding VBScript:
=====================================
for each AnObject in OurApp.Array()
counter = counter + AnObject.Value()
next
=====================================

This is the (simplified) C++ COM Code:
=====================================
VARIANT COurApp::Array()
{
  HRESULT hr;

  SAFEARRAY * pSa;
  pSa = SafeArrayCreateVector(VT_VARIANT, 0, 100000);

  LPVARIANT psadata = NULL;
  hr = SafeArrayAccessData(pSa, (void**)&psadata);
  if (FAILED(hr)) {
    SafeArrayDestroy(pSa);
  }
  LPDISPATCH t = GetIDispatch(FALSE);
  for (unsigned i = 0; i < 100000; ++i) {
    psadata[i].pdispVal = t;
    psadata[i].vt = VT_DISPATCH;
    t->AddRef();
  }

  hr = SafeArrayUnaccessData(pSa);
  if (FAILED(hr)) {
    SafeArrayDestroy(pSa);
  }

  VARIANT rgvar;
  VariantInit(&rgvar);
  V_VT(&rgvar) = VT_ARRAY|VT_VARIANT;
  V_ARRAY(&rgvar) = pSa;
  return rgvar;
}

float COurObject::Value()
{
  return rand();
}
==========================================

The returned Array can in some cases be very large. For this example,
VBScript uses 1,5 Megs and Python uses about 500 Megs of RAM.

I have set breakpoint on malloc and free in the runtime library and have
observed that Python calls these functions frequently, which I suspect is
part of the problem.

What can we do to optimise our application / script? Any hints / pointers
are much appreciated.

Thanks.

Roger,

Attached are 2 scripts (ado-mem-test-04.py, ado-mem-test-05.py) for 
testing possible ADO memory leak problems.

ado-mem-test-04.py appears to exhibit a steady increase in memory 
requirements with time; ado-mem-test-05.py does not appear to exhibit 
this behavior.

The primary difference between the two scripts is that -04 changes its 
insert value each time via a prepared statement parameter while -05 
simply uses the database table column default value (NULL) for each insert.

I apologize for the length (~65 lines) of each script.

Thanks for taking a look at this.

-- jv

P.S.
The scripts have always been run using python.exe rather than pythonwin, 
and my observations on memory usage come from the Windows Task Manager.

Hello Guillaume,

I will tell you what I know (but I am not knowledgeable about this):

The Dispatch parameter is most likely a string.  For example:

    * Dispatch('Excel.Application')
    * Dispatch('InternetExplorer.Application')

I have no advice to offer on determining what the string is for your 
particular application.

Looks like there's a refcount leak in the date conversion somewhere.
Distilled down some more, if you change the last few lines of the script to

parameter       = command.Parameters.Item('@%s' % column.Name)
for x in xrange(10000):
    parameter.Value = datetime.datetime.now()

the total refcount increases by ~100k every time you run it.
Now that we know where it is, shouldn't be too difficult
to fix it.  I'll take a close look at the C++ date conversion
code tomorrow.

You can see this in the VB application.

  import win32com.client
  ob = win32com.client.Dispatch( "ScandiagOCX" )
  ob.Telechargement( ... )

Bonjour !


Le ProgID est une cha?ne de caract?res.
A chaque ProgID est associ? un CLSID (cha?ne de chiffres et lettres entre 
accolades).

Perso, je trouve les ProgID avec Regedit, dans
    HKEY_CLASSES_ROOT\CLSID\...\ProgID
(o?  ...  est le CLSID)

Le CLSID peut ?tre affich? avec VB (et sans doute aussi le ProgID).

Sinon, il existe des utilitaires pour cela.

Bon courage.

Since the first call to calculatefield_management succeeds with the 
same argument types, I think this is not related to Python nor the 
Pythonwin wrapper.
Check the docs for that function or contact the vendor.

Could you try executing win32com\client\makepy.py as a script (eg, from a
cmd-prompt), then select the typelib from the list that will be displayed,
and see if it works there?  According to the traceback, win32com believes it
successfully generated the file, but then failed to locate it.

  Hi,

  We are sometimes getting the error below when running a Python script in
our app.

  We are calling AddTypeLib on the IActiveScript interface.

  It always works with VB-scripts and sometimes fails with Python.

  What could be the problem?

Thanks Roger!

I've reproduced the leak in the test suite (there were no tests for a
'datatime package' object before :( and identified the leak.  I may not
check it in today though, but wanted to make sure you didn't spend any more
time on it!

Thanks,

Makepy.py works and generates code for the complete typelib (including
all methods). The generated python file is placed in win32com\gen_py.
By method code I mean code like this:

	def Exit(self):
		"""Exits the application"""
		return self._oleobj_.InvokeTypes(58, LCID, 1, (24, 0), (),)

With AddTypeLib, the partial code for the typelib is placed in a
subdirectory of win32com\gen_py.With partial I mean that there is no
code generated for the methods.

If i delete the generated files and call AddTypeLib, it always fails.
If I call it when there is generated typelib data available, it works.

Thanks

I have investigated this further and found that python appears to
compile the Value call for each loop iteration (dynamic.py, row 300).
The compiled python objects are somehow kept during the lifetime of
the script. Is this correct?

Is is possible to use early binding (with the code generated from
makepy) in a self-hosted python script?

Thanks

That is not expected.  _make_method_ stores a copy of the method in
self._builtMethods_ (line 309).  A further __getattr__ for that name should
locate it.  You may have found a 'bug' (or maybe it should be called an
un-optimization) when the default method name is used though - what is the
callstack?

> Is is possible to use early binding (with the code generated from

I'm not sure what you mean by 'self-hosted'.  If you mean py2exe, then that
tool supports a 'typelibs' attribute which can package and use makepy
generated files.  Google might help you there, but sadly the examples and
docs are a little light at the moment.

Message-ID: <D6ED71480E91B94AAD39D7A7F2771A382E6A26@HERMES.FORSK.com>

 
Dear python-win32 volunteers

(I resent this mail because before I was not a subscriber)

I was hopping to manage to introduce python into our product, starting
with testing utilities and then who knows ...

But I am blocked with the following:

I am trying to write a client application that uses our com server
(automated) interface.
Usually VB scripts or C++ programs provide these client applications.
I use early binding by running makepy.
I manage to access all propertied, yet do not manage to call methods.
The InvokeTypes() fails:

For example, if I call
Obj.Item(7)
I get:

File
"C:\Python24\lib\site-packages\win32com\gen_py\A9ADC630-3FE3-11D0-935B-0
00000000000x0x1x0.py", line 206, in Item
    ret = self._oleobj_.InvokeTypes(5, LCID, 2, (9, 0), ((3, 1),),iIdx)
com_error: (-2147352562, 'Invalid number of parameters.', None, None)

yet if I call
y = Obj[7] I pass by the standard method _NewEnum() and I manage to get
my object.
 
def _NewEnum(self):
 iid =  '{1DA961EB-FB92-484C-84F4-F39BA9370C86}'
 par = self._oleobj_.InvokeTypes(-4, LCID , 2, (13,10),())
 return win32com.client.util.WrapEnum(par,iid)
		 
In this case, InvokeTypes() seems to succeed.

Do you have any idea of what is wrong? 

I tried to switch from (9,0) (3,1) being a DISPATCH return value, to
(13,0) being a IUNKNOWEN returen value ... but no good.

I have very little time left now,  if I don't solve this problem, I will
have to do my tests in VB script (yack)  

Please help 

Thanks in advanced

PS an other information that may help: 

I tried to switch to late binding by removing the 
A9ADC630-3FE3-11D0-935B-000000000000x0x1x0.py
File. In this case, the methode Item() was called, yet with my c++ 
Debugger I could see that the VARIANT variable had a VT_ERROR type.

I've set a breakpoint on PyParser_ParseStringFlagsFilename. It gets
called for every iteration of the loop, with the same arguments. For
each call, the process memory usage grows by 4-5 K.

PyTokenizer_FromString
PyParse_ParseStringFlagsFileName
Py_CompileStringFlags
builtin_compile
PyCFunction_Call
PyEval_EvalFrame
PyEval_EvalCodeEx

The arguments for PyParse_ParseStringFlagsFileName are:

s = "def AttValue(self, Attribut=pythoncom.Missing):..return
self._ApplyTypes_(1, 2, (12, 0),((9, 1),), 'AttValue', None,
Attribut....)."
filename = "<COMObject <unknown>>"

This appears to come from line 300 in dynamic.py.

I mean a self hosted script, running through an inproc ActiveScript
python engine.

This is related to the other question I have with AddTypeLib. The
function doesn't seem to generate any python Code for the actual
methods. I would like to use the complete typelib information (with
method code) in a python script.

I am not really sure how to debug the python com code. I have tried
enabling the debug output in dynamic.py, but I am only getting
incomplete information.

Hi,

Is it possible to (forcibly) unload the python engine after executing
a python script?

I would like to have the Dlls unloaded after Release in the following code:

#define WINVER 0x400
#define _WIN32_WINNT 0x400

#include <windows.h>
#include <ObjBase.h>
#include <activscp.h>

int main(int argc, char* argv[])
{
  CoInitializeEx(0, COINIT_APARTMENTTHREADED);
  GUID clsid;

  HRESULT hr = CLSIDFromProgID( L"Python", &clsid );

  IUnknown* tmp = 0;
  if (S_OK == hr) hr = CoCreateInstance(clsid, NULL,
CLSCTX_INPROC_SERVER, IID_IActiveScript, (void **)&tmp);
  if (tmp) tmp->Release(); // python still loaded at this point?

  return 0;
}

Thanks

That's unfortunate.  It may be something specific to the AXScript support,
and I can't repro that using a 'normal' dynamic Dispatch object.  I ran out
of time to try and repro something similar with IE.

The intent is that all wrapper objects will be generated "on demand", as the
objects are referenced. Running 'makepy.py -d' does the same thing, as does
the various 'bForDemand' params used internally.

Nope - Python has no facility for unloading extension modules, which means
that repeated Inits and Terms in the same process tends to be problematic -
and as a result we don't finalize at all.  We used to, but it didn't release
anywhere near everything and the pain was worse than the gain.

Is it possible you are looking for SetItem()?

The CalculateField method uses VBScript, which does not support the FORMAT command. Try doing a search for "VBScript" and "FORMAT" to find an alternative method of formatting the date in a text field.  As mentioned before this is not a Python issue. For future ArcGIS scripting questions, you will be better off posting to the ESRI forums: http://forums.esri.com/forums.asp?c=93.

method 1,2,3,5 can work, not method 4.

My result is:

method 1,2 works right when try 'elem.tagName', 'elem.id', 'elem.innerText', 'ev.clientX',
but never works when try 'doc.body.createTextRange()' whether file
'3050F1C5-98B5-11CF-BB82-00AA00BDCE0Bx0x4x0.py' exist. 

*** method 3 works right when '3050F1C5-98B5-11CF-BB82-00AA00BDCE0Bx0x4x0.py' do NOT exist ***,
but works like method 1,2 when file '3050F1C5-98B5-11CF-BB82-00AA00BDCE0Bx0x4x0.py' exist.

method 4 never get works, just I think may be works. 

method 5 can always works when file '3050F1C5-98B5-11CF-BB82-00AA00BDCE0Bx0x4x0.py' NOT exist,
but never works when file '3050F1C5-98B5-11CF-BB82-00AA00BDCE0Bx0x4x0.py' DO exist.

These code run under:
Windows XP SP2
Internet Explorer 6.0.2900.2180.xpsp_sp2_rtm.040803-2158
PythonWin 2.4.3 (#69, Apr 11 2006, 15:32:42) [MSC v.1310 32 bit (Intel)] on win32.
pywin32 build 209

My question:
It looks like that:
'doc.body.createTextRange()' never works right, whenever makepy.py generate 
{3050F1C5-98B5-11CF-BB82-00AA00BDCE0B} python wrapper before run these code,

Noticed that in method 3,  'd = WithEvents(doc, DocEvents)' will generate this wrapper, but works right
at first time when this wrapper not generate before.
But works wrong when this wrapper already exist.

I don't know why this wrapper effect method 5, since method 5 never handle {3050F1C5-98B5-11CF-BB82-00AA00BDCE0B}.

Method 1,2 always generate this wrapper file, and never works right whether this wrapper exist.

And I notice that, when generate this wrapper file, my application memory consumption will grow up to 180MB, and
60MB when do not generate it.

Any advice will be appreciated.

Thanks,
Richard

Hello Tor,

Are you familiar with the Performance Monitor (perfmon)?  If not, that 
may fit your needs.  -- jv

Sorry, very quick answer. You can do this sort of thing
fairly easily with WMI. If you Google around for Wmi
process monitoring, you'll probably find VBS examples which
will be quite easy to port to Python.

At a guess, there's some kind of oddity with the
type information.  If you use a dynamic dispatch
for the body, it seems to work in the -1 example.

Changing the last 2 lines of the Ononclick event
code to

        body=win32com.client.dynamic.Dispatch(doc.body)
        print 'body text' , body.createTextRange().text

gives the expected result.

Message-ID: <96dd15190608311443j49a520d2l6608c13efc961d19@mail.gmail.com>

Hi John I had the same problem recently except I'm using windows XP home
but it should work the same.

The trick is that you cannot access the method directly by calling it as for
some reason process.GetOwner is an integer 0 (perhaps the return code
of the method or something). What you have to do is use the execMethod_
function.

so your code would look something like this:

for proc in procs:
        result = proc.execMethod_('GetOwner')
        print "%s's owner is %s" % (proc.Name, result.User)

And similar replacements with the other calls to GetOwner.
execMethod_ returns an object with two feilds User and domain.

Hope this is what you were looking for
