It would help alot if you could provide some sample code, and the full
traceback you get.

I am not asking for a very detailed comparison that i know no one will give
i am just wondering for windows development which language would be better?
What i mean is GUI apps, interfacing with excel,word and outlook etc..

Thanks

Well, for one, Python requires a lot less code to accomplish the same task:

The following is a very simple C# program, a version of the classic 
"Hello, world!" example:

class ExampleClass
{
    static void Main()
    {
        System.Console.WriteLine("Hello, world!");
    }
}


Th Python equivalent is:

print "Hello, world!"

With the assistance of Mark Hammond's excellent pywin package, COM 
interfacing is at least as easy as in other languages:
import win32com.client
xl = win32com.client.Dispatch("excel.application")
xl.visible = True
wb = xl.WorkBooks.Open(filename)
sh = wb.Sheets(1)
etc.

There are various GUI toolkits available. I've not done much with them.

Sorry, I know nothing about .NET. Perhaps some other list lurker can 
speak to that. Or could you provide an example of a .NET class and its 
usage in C#?

If you're interested in using Python with .NET, you should check out IronPython:

http://www.codeplex.com/Wiki/View.aspx?ProjectName=IronPython

They've implemented Python in .NET.  Personally, I've never used it.

It depends on what you need to do.  The .NET class library is, of
course, far more extensive than the Python standard library even with
the Win32 extensions, but for most tasks, you don't NEED the vastness of
the CLR.

It might be interesting for you to investigate IronPython.  This is an
implementation of Python as a full .NET language, with access to the
entire Common Language Runtime.

You can have the best of both worlds with IronPython.

Python is syntactically and semantically more concise than C#, with 
language features like higher order functions, list comprehensions, 
standard polymorphic containers and much more.

IronPython allows you to use .NET classes - and the interface with C# is 
basically seamless (except for .NET attributes).

At Resolver we have a 20 000 line IronPython application (plus around 75 
000 lines of test code) which has just gone to our first customer. I 
highly recommend it - particularly if you have .NET experience.

Where CPython beats IronPython is cross-platform capabilities. On the 
other hand, Windows Forms (.NET) is better than any GUI toolkit I've seen.

Newbie question..

I am trying to connect to a COM object.. and I can't figure how to code it..

In Makepy the name of the COM object is:

   OTA COM 9.0 Type LIbrary (1.0)

The DDL is:

   OTAClient.dll

The VB samples have stuff like this..

   Dim td as New TDConnection
   td.InitConnectionEx "http://<servername>:port/qcbin"
   etc...

What should my.....

   obj=win32com.client.Dispatch("...........

...look like?

thanks!

It should be as simple as
    td = win32com.client.Dispatch( "TDConnection" )
    td.InitConnectionEx( "http://server:port/qcbin" )

That is, assuming they support late binding.

Message-ID: <200704031717.40946.tchough@tchough.com>

Hi all,

I'm writing a win32 service in Python.  I'd like to add a tray icon displayed 
whenever the service is running.  I have played around with SysTrayIcon.py 
[1], but if a user logs off and logs back on, the tray icon disappears even 
though the service is still running.  I think the answer is probably getting 
my service to recreate the icon whenever a logon event happens.  I don't 
really know much about win32 programming, though.  Can someone point me in 
the right direction to solve this problem?

Thanks,
TC

You really need to consult the documentation for the object itself.

Try opening the file generated by makepy - if you are lucky, you will find a
comment along the lines of:

  This CoClass is known by the name 'Some.Name.Here'

Services have trouble interacting with the desktop.  The general approach is
to have a dedicated taskbar application that communicates with the dedicated
service using some kind of IPC.

You tell us! :)  But quite possibly.  If that is the only occurance, it
probably is.  If there are others, you probably need to inspect the methods
available to work out the correct one.

IronPython can use standard CPython modules though, right?  I've dropped
my ipy.exe in C:\Python25 and it doesn't seem to have a problem with
things like os.path, which isn't available in IP (unless I'm doing
something brain dead).

Out of interest, have you ever used Qt/PyQt?  Qt blew MFC-style apps out
of the water in terms of developer friendliness a few years ago (which
is when I switched to it for all our C++ development, which is why I'm
somewhat biased).  I'd be interested to hear from others in a similar
situation that can provide a comparison between Qt/PyQt and Windows
Forms .NET.

IronPython and Windows Forms, which might be of interest.

You're right. If you add the standard library to your path then *most* 
of the pure Python modules 'just work'.

I've never used Qt I'm afraid. Windows Forms seems like a generally sane 
and friendly API - even when called from Python. :-)

This is great - we have our own internal version of an ADO DBAPI-2
Python library that we use internally and tried to release at some stage
(around the same time as adodbapi) but to little interest so haven't
kept up a public version. I tried to look at merging it with adodbapi at
one point but got a bit swamped...

Message-ID: <4866bea60704040846h3cdee7aeid7b96ca6df326424@mail.gmail.com>

The servicemanager implementation writes an entry into the windows
error log when an exception causes a service to drop out of DoRun.
This works great with Python2.4, but with Python 2.5 I don't get the
error messages. I'm using the prebuilt installers from the SF site,
version 210 for both. This affects both py2exed executables and when
running via PythonService.exe.

I'm pretty lost on what the problem might be, does anyone have any suggestions?

IronPython is a *great* way to learn .NET. Particularly via the 
interactive interpreter.

Instantiating and configuring classes is a lot simpler without all the 
C# boilerplate.

*pure python* modules, note, not C extension modules.

"Python for .NET" (http://pythonnet.sourceforge.net/) is like ctypes
for .NET - it allows you to load, call, even subclass .NET classes
from within CPython.

Just a quick follow-up..

Since getting past the issue of how to determine the name of the COM
object... my programming adventures of scripting to access Mercury
Quality Center has been insanely great. The first thing I did was
'port' some of the VB examples to Python and just in number of lines
the Python versions had 2/3rds the number of lines as compared to the
VB versions.

Again.. thanks everyone!

I can't reproduce this.  If I change win32\Demos\service\pipeTestService.py
to raise an error in the SvcDoRun() function, after starting the service I
see the exception in the event log.  Were both 2.4 and 2.5 installed with
admin rights?

Yes, there both installed from the stock python.org installers and
"for all users" by an admin user.

Update - it's working for my own services now, too. I rebooted last
night to install patches, perhaps there was a bad message dll or
something was stuck in memory.

Subject: [python-win32] How to make a window client area "transparent"
Message-ID: <79990c6b0704071249o3d19fe83t9abe6bba172f6bf8@mail.gmail.com>

This is only vaguely a Python related question - I'm writing Python
code, but the basic issue I have is with Win32 programming regardless
of language - but I don't know a really good forum for Win32 API
technical coding questions (aside: can anyone point me to such a forum
- high signal-to-noise ratio, focus on Win32 API rather than .NET or
similar?)

What I want to achieve is client-area transparency for a window -
essentially, make the client area transparent, without the window
border, title bar, etc being transparent. I'm aware of layered windows
and alpha blending - but this affects the window border as well as the
client area, so it's not what I'm after.

Is what I'm looking for possible? If so, can anyone give me a pointer
to how to achieve it?

On a slightly related note, I know I can use SystemParametersInfo with
SPI_GETDESKWALLPAPER to get the filename of the bmp file being used as
the desktop wallpaper - but can I get the method that bitmap is used
(stretch, center or tile)? I want to replicate (part of) the desktop
in a window, and without that information, I'm a bit stuck!

Thanks, and sorry for the off-topic post.

Paul.

Subject: [python-win32] Constants quit working under Python 2.5
Message-ID: <496229.53767.qm@web51402.mail.re2.yahoo.com>

Hi list,

I upgraded to Python 2.5 for evaluation and testing.   After installing the pywin32-210.win32-py2.5.exe, I found that the constants module doesn't work.  For example, this code fails:

   from win32com.client import Dispatch, constants

   print constants.xlDown

I re-execute makepy.py and selected "Microsoft Office 10.0 Object Library (2.2)" but the problem persists.

What should I do?

Thanks,

xlDown appears to be in the Excel object library rather than
the Office object library.

Can't help here, I'm afraid, except to say that if you can spot
an opensource project already doing what you want, might
be worth going through their code to see how they do it.
(Although it might be mired deep in wx / Qt / whatever).
Likely candidates are the IM/email clients which seem to
use such effects.

This one I can help with, at least from the WMI direction (!). You can
interrogate the Win32_Desktop classes for that information. The complication
is that WMI doesn't know which user's desktop you want, since it's running
as a service not as a user (if you see what I mean). In any case, here's the
starting point; I really must find a more elegant way to handle associators.

<code>
import wmi
import win32api
c = wmi.WMI ()
for this_machine in c.Win32_ComputerSystem ():
  for user in this_machine.associators 
(wmi_result_class="Win32_UserAccount"):
    if user.Name == win32api.GetUserName ():
      for desktop in user.associators (wmi_result_class="Win32_Desktop"):
        print desktop.Wallpaper, desktop.WallpaperStretched, 
desktop.WallpaperTiled

</code>

Obviously you could also do it this way:

<code>
import getpass
import socket
hostname = socket.gethostname ()
username = getpass.getuser ()
desktopname = "%s\\%s" % (hostname, username)
for desktop in c.Win32_Desktop (Name=desktopname):
  print desktop.Wallpaper # etc.
</code>

Chances are there's a more straightforward win32api-ish way of doing
this, but this approach certainly works.

Are you simulating Vista behavior on non-vista system, or do you want a
glass-enabled application on vista?
If the latter, then I suspect there are better api:s to start from,
unfortunately I'm not familiar with them and cannot give any further
pointers..

I'm doing this on XP. If it's a Vista look, I wasn't aware of it...
:-) Thanks for the information, though, it might help me in some
google searches.

And thanks to Tim for the info on how to get the desktop info from WMI.

Subject: [python-win32] uAnn: WMI 1.3 *and a tutorial*
Message-ID: <46190991.3010607@timgolden.me.uk>

I've finally got round to putting together a tutorial for the WMI 
module, covering the basics and some advanced stuff. I've uploaded it to:

   http://tgolden.sc.sabren.com/python/wmi-tutorial.html

along with release 1.3 of the WMI module itself, which adds
support for Extrinsic events.



*****************
Python WMI Module
*****************

What is it?
===========

Windows Management Instrumentation (WMI) is Microsoft's implementation 
of Web-Based Enterprise Management (WBEM), an industry initiative to 
provide a Common Information Model (CIM) for pretty much any information 
about a computer system.

The Python WMI module is a lightweight wrapper on top of the pywin32
extensions, and hides some of the messy plumbing needed to get Python to
talk to the WMI API. It's pure Python and should work with any version 
of Python from 2.1 onwards (list comprehensions) and any recent version 
of pywin32.


Where do I get it?
==================

Copyright & License?
====================

(c) Tim Golden <mail at timgolden.me.uk> 5th June 2003
Licensed under the (GPL-compatible) MIT License:
http://www.opensource.org/licenses/mit-license.php


How do I install it?
====================

When all's said and done, it's just a module. But for those
who like setup programs:

python setup.py install


Prerequisites
=============

If you're running a recent Python (2.1+) on a recent Windows (2k, 2k3, 
XP)and you have Mark Hammond's win32 extensions installed, you're 
probably up-and-running already. Otherwise...

   Windows
   -------
   If you're running Win9x / NT4 you'll need to get WMI support
   from Microsoft. Microsoft URLs change quite often, so I suggest you
   do this: http://www.google.com/search?q=wmi+downloads

   Python
   ------
   http://www.python.org/ (just in case you didn't know)

   pywin32 (was win32all)
   ----------------------
   http://starship.python.net/crew/mhammond/win32/Downloads.html
   Specifically, builds 154/155 fixed a problem which affected the WMI
   moniker construction. You can still work without this fix, but some
   more complex monikers will fail.

How do I use it?
================

There's a tutorial at http://timgolden.me.uk/python/wmi-tutorial.html 
and examples at: http://timgolden.me.uk/python/wmi_cookbook.html
but as a quick taster, try this, to show all stopped services:

import wmi

c = wmi.WMI ()
for s in c.Win32_Service ():
   if s.State == 'Stopped':
     print s.Caption, s.State

Thanks for the reply.

That's the one I've been using before the migration to 2.5.  I went back and tried both Microsoft Excel 10.0 (1.4) and 5.0 (1.0) Object Library and the failures are the same.

Subject: [python-win32] Emulate a keystroke for Kbhit function (Conio.h)
Message-ID: <001501c77b55$df7e9540$1a6fa8c0@tracetronic.local>


Hi All,

I've automated a console application using win32pipe.popen2 by capturing the
output stream and writing the input stream. So far it works fine but the
console application uses Kbhit() from conio.h in some cases. Is there a
possibility to fill the keyboard buffer and emulate a keystroke for the
process opened by win32pipe? 
Win32api.SendMessage can't be used because there is no window for the
console application. The user keystrokes are captured by my wx-application
that automates the console application but I don't know how to forward the
keystroke to Kbhit.

Ciao,
 Frank

Subject: [python-win32] Recovering a DLL with ctypes from a VB project
Message-ID: <461B81CF.7010505@rastertech.es>

Hello.

I have an old VB project using a dynamic library. I thought it would be 
good to use this from Python through ctypes. However, the information of 
function names in the dll is stripped. If I open the dll with the 
dependency viewer I get something like:

    4 (0x0004) Function N/A Entry point 0x0006C3A8
    6 (0x0006) Function N/A Entry point 0x00001000
    ...
up to entry 1081.

However, the VB project using this DLL contains a "Public declare" file 
which only uses 22 functions, and they are in the form:

    Public Declare Function DllGetVersion _
                            Lib "LIBDLL" _
                            Alias "#2" _
                            () _
                            As String

where the only thing changing is the name of the function, the alias 
number and the type of parameters (this function doesn't require any). 
The aliases start with "#1" and go up to "#21".

Now, how do I relate this into Python? I can access the DLL:

    dll = ctypes.windll.LIBDLL

    prototype = ctypes.WINFUNCTYPE(ctypes.wintypes.LPCSTR)
    GetDllVersion = prototype(dll[6])
    print "GetDllVersion: '%s'" % repr(GetDllVersion())

So I thought the alias #2 thingy specifies the order inside the DLL, 
which would be function 6, since that is the second one. But the result 
I'm getting is

    GetDllVersion: ''  \x07\x10D''

The respective VB code would be:

    MsgBox ("Version " & DllGetVersion)

Which outputs:

    Version 1.3.0 (Build 403)

Far different from what I'm getting in python. So how can I use the VB 
declaration file to access the DLL the same way? Unfortunately the DLL 
doesn't expose the names, so I can only access functions with the 
attribute getter using an index.

I tried to search for the function using a loop over all the functions, 
but that seems to hang up on nearly every second function. Besides, I 
might be doing something wrong with the return value.

Any suggestions?

Not at all my area, I'm afraid, but I have thought about
it a bit. Console windows do have a window handle (which
you can get hold of via the win32console functions) so
there *might* be a way of sending keys to it, but I'm
not at all sure of the interactions between the Windows
messaging and c-lib things like kbhit.

This is really pexpect territory which doesn't seem to
be available under Windows (unless you're prepared to
try Cygwin which I can never bring myself to like).

Message-ID: <71b6302c0704101038x7653d08ax5dd237a731e36c4d@mail.gmail.com>

Hi,

0.3.7 release of pywinauto is now available.

pywinauto is an open-source (LGPL) package for using Python as a GUI
automation 'driver' for Windows NT based Operating Systems (NT/W2K/XP/Vista?).

SourceForge project page:
http://sourceforge.net/projects/pywinauto

Download from SourceForge
http://sourceforge.net/project/showfiles.php?group_id=157379


Here is the list of changes from the previous release (0.3.6):

0.3.7 Merge of Wait changes and various bug fixes/improvements
------------------------------------------------------------------
10-April-2007

* Added Timings.WaitUntil() and Timings.WaitUntilPasses() which
  handle the various wait until something in the code. Also
  refactored existing waits to use these two methods.

* Fixed a major Handle leak in RemoteMemorBlock class (which is
  used extensively for 'Common' controls. I was using OpenHandle
  to open the process handle, but was not calling CloseHandle()
  for each corresponding OpenHandle().

* Added an active_() method to Application class to return the
  active window of the application.

* Added an 'active' option to WindowSpecification.Wait() and
  WaitNot().

* Some cleanup of the clipboard module. GetFormatName()
  was improved and GetData() made a little more robust.

* Added an option to findwindows.find_windows() to find only
  active windows (e.g. active_only = True). Default is False.

* Fixed a bug in the timings.Timings class - timing values are
  Now accessed through the class (Timings) and not through the
  intance (self).

* Updated ElementTree import in XMLHelpers so that it would work
  on Python 2.5 (where elementtree is a standard module) as well
  as other versions where ElementTree is a separate module.

* Enhanced Item selection for ListViews, TreeViews - it is now
  possible to pass strings and they will be searched for. More
  documentation is required though.

* Greatly enhanced Toolbar button clicking, selection, etc.
  Though more documentation is required.

* Added option to ClickInput() to allow mouse wheel movements
  to be made.

* menuwrapper.Menu.GetProperties() now returns a dict like all other
  GetProperties() methods. This dict for now only has one key
  'MenuItems' which contains the list of menuitems (which had been
  the previous return value).


Thanks
 Mark

You should be able to use PyConsoleScreenBuffer.WriteConsoleInput
to send keystrokes to the app.  The tricky part will be getting a handle
to the console for the child process.

Try clearing out your gen_py folder and starting from scratch.
The below works for me with 2.5.

>>> import win32com.client
>>> xl=win32com.client.gencache.EnsureDispatch('Excel.Application',0)
>>> print win32com.client.constants.xlDown

Message-ID: <461E3CA3.2010607@rastertech.es>

Hello.

I want to embed an ActiveX control in a program and I see that the 
webbrowser example works very well replacing the appropriate lines. 
However, the webbrowser example doesn't run outside of the Pythonwin 
environment, as many other examples.

What would I need to do to make the webbrowser a standalone script which 
I could py2exe it later?

Message-ID: <1938.204.13.132.6.1176400376.squirrel@mail.wirelessbeehive.com>

Greetings, all:
   I have collected all of the patches I could find, and have included
them along with some of my own code to create an updated version of
adodbapi.
  This should really be published on the sourceforge project, but since
the project administrator is no longer available, I am hosting the
release candidate on an old linux box at my home.  Please be gentle with
downloads.
  Mark Hammond has kindly invited me to include adodbapi in a future
version of the win32all package. I believe that would be best for all
and plan to accept his invitation rather than attempt to take over the
sourceforge project.

The temporary site for the release candidate(s) is:
ftp://ftp.vernonsComputerShop.com


Prerequisites:
* Python 2.3 or higher.
* Mark Hammond's win32all python for windows extensions.

Whats new in version 2.1?
1. Use of Decimal.decimal data type for currency data.
2. add optional timeout parameter to the connect method i.e.:
      adodbapi.connect( connectionString, timeout=60)  [thanks to: Patrik
Simons]
3. improved detection of underlying transaction support [ Thomas Albrecht ]
4. fixed record set closing bug and adoRowIDtype [ Erik Rose ]
5. client-side cursoring [ Erik Rose ]
6. correct string length for qmark parameter substitution [ Jevon a.k.a.
Guybrush Threepwood ]
      This appears to correct the "One Character In Each Field" bug.
7. replaced the try-four-strategies parameter substitution with a single,
more introspective method.
8. separated the test scripts from the core module


--
TO DO --  may need to add CoUninitialize to the connection.close()
      --  controls are unreliable, sometimes adodbapi.verbose=True works,
      other times must use adodbapi.adodbapi.verbose=True to get the same
effect.

It would be very difficult to try and host a web browser control in a
non-GUI application.  You really are limited to hosting it in either
pythonwin or wxWindows.  You should be able to get both of those
environments working with py2exe, but it might not qualify as a "standalone
script" for you.

Cheers,

Mark

It would, I didn't explain myself properly, sorry. When I double click 
the createwin.py example it opens a dialog with a control and just 
works. When I double click the webbrowser.py it asks me to be run from 
inside Pythonwin. I should have asked my question this way: How do I mix 
createwin.py and webbrowser.py to have them run without opening 
pythonwin separately and later creating a binary with py2exe?

Much longer, though.

The reason why I wanted to do this is because I want to embed a the 
crystal reports activex component in a wxpython application, but my 
first tries didn't work. OTOH modifying webbrowser.py was easy and 
worked, but only inside pythonwin.

By now I've managed to successfully run the activex component inside 
wxpython, so I won't need help with the createwin+webbrowser question, 
though I'm still interested on the technical reasons why one works and 
the other doesn't (I'm a total newbie to win32 programing).

 
http://lists.wxwidgets.org/cgi-bin/ezmlm-cgi?11:msn:63578:ihehakhbfokpnmnnafdc

The example code posted in the above URL doesn't use wxPython's activex 
module because it doesn't allow me to specify the version of the activex 
control along with the clsid string, unlike gencache's EnsureModule().

I wonder what trickery does win32com to locate the correct version of 
the clsid, which wxpython is unable to do.

Hi,

The problem may be the following...
"C:\Program Files\TestApp\Program\EXLXL32.XLL" != r"C:\Program
Files\TestApp\Program\EXLXL32.XLL"

Otherwise I have no idea about XLL files :-)

Yes, Mark is exactly right.  The "\T" in your file name is actually a
"tab" character, rather than the two characters you think it is.  You
have three choices:
1. Double the backslashes:  "C:\\Program
Files\\TestApp\\Program\\EXLXL32.XLL"
2. Use the "r" syntax: r"C:\Program Files\TestApp\Program\EXLXL32.XLL"
3. Use forward slashes:  "C:/Program Files/TestApp/Program/EXLXL32.XLL"

Any of them will work.  Choose the one that makes the most sense to you.

Dear all,



I am looking for an option to create a standalone python scripting
engine (in contrast to regularly installing python and registering the
Python Scripting Engine with axscript\client\pyscript.py). The goal is
to make python scripts (.pys) visible to cscript, without installing
python system-wide.



Any ideas are appreciated,

Maybe Portable Python (http://www.portablepython.com/,
http://www.voidspace.org.uk/python/movpy/)?

Or you could write a python script that takes a python script as an argument
and executes it, then freeze that using py2exe (http://www.py2exe.org/) or
cx_freeze (http://python.net/crew/atuining/cx_Freeze/) or some such tool. (I
don't think that would be recommended, or work very well thought, but just
giving you some ideas as to things to look into)

Message-ID: <e3c91420704180615y35b96a58taf1ab0efc537082e@mail.gmail.com>

I am attempting to add a simple thumbnail preview in a wxpython app I'm
putting together. IExtractImage seems to be the way to access the thumbnails
that Windows Explorer uses.

(I can't use PIL or similar because I'm previewing AutoCAD .dwg files).

I am adapting some Delphi COM code (from
here<http://www.delphi3000.com/articles/article_3806.asp?SK=>)
as follows--i've removed the Malloc and other unnecessary statements:

--begin delphi code--

if NOERROR = SHGetDesktopFolder(DesktopFolder) then
 DesktopFolder.ParseDisplayName(0, nil, 'C:\WINNT', Eaten,
    ItemIDList, Attributes);
  DesktopFolder.BindToObject(ItemIDList, nil, IShellFolder,
    TargetFolder);
  TargetFolder.ParseDisplayName(0, nil, 'delphi_wallpaper1024.bmp', Eaten,
    ItemIDList, Attributes);
  TargetFolder.GetUIObjectOf(0, 1, ItemIDList, IExtractImage,
    nil, XtractImg);
  Malloc.Free(ItemIDList);

--end delphi code--


--begin python adaption--

        testPath = "C:\\"
        testFileName = "test.dwg" #also have tried test.bmp, test.png
        iSHFolder = shell.SHGetDesktopFolder()
        eaten, idList, attr = iSHFolder.ParseDisplayName(0, None, testPath)
        targetFolder = iSHFolder.BindToObject(idList, None,
shell.IID_IShellFolder)
        eaten, targetIdList, attr = targetFolder.ParseDisplayName(0, None,
testFileName)
        pprint ([eaten, targetIdList, attr])
        extractImage = targetFolder.GetUIObjectOf(0, [targetIdList],
                pythoncom.MakeIID
('{BB2E617C-0920-11D1-9A0B-00C04FC2D6C1}'),0)

--end python adaptation--

The python code fails on the last statement, throwing the following
exception:

TypeError: There is no interface object registered that supports this IID

Any ideas on how to use this interface in python? I have googled for hours.

Thanks,
Steven James

Here is the problem:                                          ^^^^^^^^^^^^
You are calling the unicode function with three arguments ;-).
Unfortunately, by default you do not get a traceback that points out the problem.

You can enable the tracebacks with these lines at  the top of your script:

import logging
logging.basicConfig(level=logging.WARNING)

BTW:  I see that you are using an old version of comtypes (in recent versions the CreateObject function
does not accept a 'sink' argument any longer; you have to setup the events by calling
comtypes.client.GetEvents function, and keep the returned object as long as you want
to receive the events).  Unfortunately I have never released a newer comtypes, but
you can get it with 'easy_install comtypes==dev', if you have svn installed.

Thomas

PS: I'll attach a working script that I have made, it connects to internet explorer which
is my favorite com client for testing (although I don't use it for browsing).

I'm afraid that IExtractImage is not yet exposed by pywin32 - it would not
be too hard if you are interested in testing a new implementation.  Note
that IExtractIcon is exposed - that may nor may-not work for you though.

  (I can't use PIL or similar because I'm previewing AutoCAD .dwg files).

  I am adapting some Delphi COM code (from here) as follows--i've removed
the Malloc and other unnecessary statements:

  --begin delphi code--

  if NOERROR = SHGetDesktopFolder(DesktopFolder) then
   DesktopFolder.ParseDisplayName(0, nil, 'C:\WINNT', Eaten,
      ItemIDList, Attributes);
    DesktopFolder.BindToObject(ItemIDList, nil, IShellFolder,
      TargetFolder);
    TargetFolder.ParseDisplayName(0, nil, 'delphi_wallpaper1024.bmp', Eaten,
      ItemIDList, Attributes);
    TargetFolder.GetUIObjectOf(0, 1, ItemIDList, IExtractImage,
      nil, XtractImg);
    Malloc.Free(ItemIDList);

  --end delphi code--


  --begin python adaption--

          testPath = "C:\\"
          testFileName = "test.dwg" #also have tried test.bmp, test.png
          iSHFolder = shell.SHGetDesktopFolder()
          eaten, idList, attr = iSHFolder.ParseDisplayName(0, None,
testPath)
          targetFolder = iSHFolder.BindToObject (idList, None,
shell.IID_IShellFolder)
          eaten, targetIdList, attr = targetFolder.ParseDisplayName(0, None,
testFileName)
          pprint ([eaten, targetIdList, attr])
          extractImage = targetFolder.GetUIObjectOf(0, [targetIdList],
                  pythoncom.MakeIID('{BB2E617C-0920-11D1-9A0B-00C04FC2D6C1}'
),0)

  --end python adaptation--

  The python code fails on the last statement, throwing the following
exception:

  TypeError: There is no interface object registered that supports this IID

  Any ideas on how to use this interface in python? I have googled for
hours.

  Thanks,
  Steven James

silly. Thanks. Works fine with the old version of comtypes I had installed.

Now I installed comtypes from svn and get this error running your new
example:

Traceback (most recent call last):
   File "C:\Dokumente und Einstellungen\ck\Desktop\x.py", line 64, in ?

line 358, in GetEvents
     raise TypeError("cannot determine source interface")
TypeError: cannot determine source interface

As I'm real beginner with python on windows I'd like to ask some 
elementary questions if you don't mind:
1) Does comtypes depend on pywin32?
2) It seems that it provides the same (similar) mapi interface as 
pywin32, so can it be used as a replacement for pywin32?
3) Does comtypes expose the extended mapi?

Thanks for your help, Christian

First of all, when you install a new comtypes version you should clear the
contents of the comtypes\gen directory, so that the typelib wrappers can
be regenerated.  The old versions from previous comtypes releases should
better not be used.

Second, if you are running the exact sample that I posted then it should work
for InternetExplorer, and with slight changes also for Outlook.  At least
it worked for me.

Third, the GetEvents function requires that the COM object exposes type information,
and that this information includes info about the outgoing default interface.
Some objects do not do this, then you have to find the outgoing interface yourself
and pass that as the 'interface=...' parameter to the GetEvents function (this description
is from memory, read the sources to find out).

No, it is completely independend.

I never used mapi so I cannot really answer this.
comtypes normally creates the typelib wrappers itself; when these
contain the mapi interfaces then there are chances that it would work.

> Thanks for your help, Christian

If you are a newbie to COM, and pywin32 exposes the functionality that you need
you should probably better use pywin32. It is stable, well maintained, and documented.
You should probably get the 'Python Programming on Win32' book, or at least read
the online sample chapter.

However, if you are brave, if you need to use non-dispatch based interfaces; then
comtypes may be what you want.

Hope it really helps,

Thomas

I could generate the thumbnails myself, or write a script to generate the
thumbnails, yes. Unfortunately in this case the files I'm previewing may
change at any time so pre-generation of the previews would not be possible.
I also need to be able to generate them on the fly.

I could write a server app to monitor the folders and auto-generate the
thumbnails through AutoCAD, but would require me to have a server running
AutoCAD (as I would not want to take over the client's computer for
generation of the thumbnails). I did actually consider doing this, but I
think I may put some effort in to getting IExtractImage to work, because
that would allow thumbnails of all types with the COM interface implemented,
as well as solving my immediate problem.

I have been delving in to the process of adding support for IExtractImage to
pythonwin. I have run makegw on the necessary files, added the resulting
.cpp and .h files to com/win32comext/shell/src, added references in
shell.cpp and setup.py, and now it seems all that is left to do is implement
the proper data types which makegw did not know how to handle. (Also, if it
would help anyone, I patched my makegw to run under Python 2.5 with no regex
or regsub modules.)

I have a few questions about the next steps, for those who may have done
this before:

I am left with a few lines of code in the PyIExtractImage.cpp file that look
like this:

if (bPythonIsHappy && !PyObject_AsDWORD *( obpdwPriority, &pdwPriority ))
bPythonIsHappy = FALSE;

I am assuming I either need to find or write an implementation of
PyObject_AsDWORD*. What would be the proper file to put this function in? It
looks like I need DWORD*, const SIZE*, and HBITMAP*.

Does all of this look right to you? It seems like at least DWORD should
already be written somewhere, but I can't seem to find it.

Any help/advice would be appreciated. Thanks for the responses so far.

Excellent - please feel free to send me the patches.  makegw is *very* dumb
though.

See above - makepy is dumb :)  For now, PyInt_AsLong should work fine for a
DWORD.  HBITMAP should just use PyLong_FromVoidPtr (or however that is
spelt), and a SIZE already has PyWinObject_FromSIZE.  You will just need to
correct the invalid indirections created by makegw - eg, your line above
would read as:

> DWORD dwPriority;
> if (bPythonIsHappy && !PyInt_AsLong( obpdwPriority, (long *)&dwPriority ))
bPythonIsHappy = FALSE;

Also, please see the existing support for IExtractIcon - this new interface
should be almost identical - just one or 2 data types appear to be different
between the interfaces (HICON -> HBITMAP being the most obvious one)

Cheers,

Mark

I had the comtypes directory removed before installing from svn.

Ok, I've no idea what the 'interface' is in this case. Time for a good 
book obviously.

The point why I was asking that, is, that in order to circumvent some 
silly Outlook security barrier when accessing it with simple mapi one 
has to use the extended mapi interface according to what I've understood 
from googeling. pywin32 ships with an example of how to create a new 
mail using the extended mapi and I guess this is the way to go for me.

But honestly I still know too few to even use all those acronyms properly :)

Thank you for pointing that out.

I successfully read out the Outlook inbox using comtpyes but finally 
switched back to pywin32 because I was not able to interprete the value 
of MailItem.CreationTime,
e.g:
obj.Session.Folders['mail.server.com'].Folders['INBOX'].Items.Item(1).CreationTime
which looks like a posix timestamp which dates back to the 70th. I guess 
pywin32 is doing some conversion there and comtypes is not?

Anyway I'll have a look at both again after having read some more 
documentation.

pywin32 uses the IDispatch interface, which probably returns the time in a VARIANT with
typecode VT_DATE, and of type C double.  This way the code knows that a date/time is meant
and can convert accordingly.

The outlook type library seems to use the C double also, but comtypes does not know that
a date/time is meant.  In COM, date/time is represented as double, in days since 30. Dec 1899.
In comtypes\automation is code to do the conversion from/to VARIANT instances, from what I see
there you should be able to do the conversion yourself with code like this:

import datetime
_com_null_date = datetime.datetime(1899, 12, 30, 0, 0, 0)

def double_to_datetime(days):
    "Takes a COM date/time value, a float, and returns a datetime object"
    return datetime.timedelta(days=days) + _com_null_date

Message-ID: <DC0819305D79164E8930AE64CFB9E9DD0199B28A@SeSoExMB05.scania.se>

Hi.

I'm a COM newbie so please excuse my ignorance!

I have a coclass exposing a set of interfaces to COM:

coclass ICAList {
    [default] interface _ICAList;
    interface _Object;
    interface IList;
    interface ICollection;
    interface IEnumerable;
};

The default interface "ICAList" does not have an indexer nor GetItem function, so I would like to access the non default "IList" interface.

Desired usage of indexer:

>> p = win32com.client.Dispatch("test.Class1");
>> list = p.GetICAList()
>> # Get the "IList" interface instead....somehow....?
>> for item in range(0, 5):
>>	print list[item].Name

Can this be done in Python 2.2?

Many thanks.

Here is a little hack that automatically converts COM date/time objects (doubles)
from or to Python datetime objects.  You have to insert this code near the top of the
generated comtypes.gen._00062FFF_0000_0000_C000_000000000046_0_9_1 module (this is the module
that is imported by comtypes.gen.Outlook on my system.  BTW I have outlook 2002, if you
have a different version the module name may be different).

It replaces the c_double datetype used in that module with a subclass that converts
automatically in COM method calls:

comtypes uses fairly extensive logging calls in certain areas.  You can enable this
to find out the reason.  Here is a little code snippet that shows what happens on
my system when I call GetEvents() with Internet Explorer:

<code>
from comtypes.client import CreateObject, GetEvents
import logging
ie = CreateObject("InternetExplorer.Application")
logging.basicConfig(level=logging.DEBUG)
GetEvents(ie, sink=object())
<code/>

and here is the output:

Thank your your excellent help, Mark. I have gotten everything to compile
properly, and can call IExtractImage::GetLocation and IExtractImage::Extract
from python on the necessary files. Even the exceptions on unknown file
types seem to be handled properly.

The final problem is getting the image data into python (and using it in
wxpython). The final return type is an HBITMAP, which I can see as an int in
Python using PyLong_FromVoidPtr, or as a PyHANDLE in python using
PyWinObject_FromHANDLE.

I realize that a discussion on wxpython would be outside this group's topic,
but if anyone could tell me where to start looking for a way to do this, I
would greatly appreciate it. From what I can tell, wxpython/wxwindows uses
the HBITMAP type internally to store images, and it appears to be a pointer
to a DIB in memory. If so, it may be possible to use wx.BitmapFromBuffer,
wx.BitmapFromBits, or some similar function, if I can somehow convert the
HBITMAP data (instead of the handle) to a string.

Thanks,
Steven James

Thank you very much for all your help so far. I'll be quiet for the next two

IIRC you can use wxDC.GetSafeHDC() and then win32gui to copy data to 
wxBitmap

Subject: [python-win32] excel xla runautomacros
Message-ID: <47686397d85a42d0885edcc1778452df@mpjconsultancy.com>

I am having a problem with an excel add-in which is installed via 
xlApp.Workbooks.Open("C:/Program Files/Program/XLOF32.xla").RunAutoMacros(1)

I can then add the add-in and install it via
xlApp.AddIns.Add ("C:/Program Files/Program/XLOF32.xla",True)
xlApp.AddIns.Item(Index='Excel Functions').Installed=True

My problem is that the macro may have already been run, which generates a dialog warning that it is already open.

The question, is there a way of detecting whether the add-in is already open?

Thanks
Martin

Subject: [python-win32] Registering a Server COM to make it visible in the
	reference list
Message-ID: <462F74CB.3060103@cenix-bioscience.com>

Hello,

          I have made a COM server using python and registered it using 
win32com.server.register.UseCommandLine(TrackingClient).  That all works 
fine and I can instantiate it using late binding, however I now need to 
reference that in C# or VBA in excel.  The problem I have is that when I 
lok for the server in the refernces list in VS2005 or Excel - the progId 
of this doesn't appear in the list of availa ble COM servers.  
Interestingly it does in PythonWin under the category of Python COM 
Server.  this is real pain as I would need to include the class in my 
namespace in VS2005 (Exscel was only a test - I need VS2005).  Is there 
a setting which allows me to publish this and/or is there a typelibrary 
I can generate to import in VS2005?  My details are as follows:


    _reg_clsid_ = '{AC578D8E-A6F7-4388-BE37-04E7D6A489AE}'
    _reg_progid_ = 'BarcodeTracking.SOAPClient'
    _reg_desc_ = 'ActiveX component to connect to the barcode tracking 
server'

    Thanks for your help.

Cheers,

Neil

Well, xlApp.AddIns is a collection.  You should be able to query the
collection item by item and check to see whether the add-in is present.

I'm leaving the code as "an exercise for the reader", but something like
this should be possible:
    for addin in range( xlApp.AddIns.Count ):
        if xlApp.AddIns.item(addin).Filename???
I don't know exactly which property you'd need to query.

That stops one too soon.  Remember that range(1,4) returns [1,2,3].  You
should either use range(xlApp.Application.AddIns.Count) and refer to
AddIns(ia+1), or you should use range(1, xlApp.Application.AddIns.Count+1)

Subject: [python-win32] updating a registered com server
Message-ID: <79b79e730704252324g6cc53dcdg7146109b1fd5abf3@mail.gmail.com>

Hello,

this is my first post to the ml. I am rather new to python under windows, so
probably mine is an easy question, but I've searched for a solution and
found none.
I am writing a (set of) simple COM servers, which basically take the input
from excel worksheets, do some computation, invoke some C++ dll and return
the output on some other excel sheet.
I'm working on winXp professional, with active python 2.5 and excel 2002.
I've been able to make a first prototype of the thing working (enough for
being encouranged to further go on pythonizing the various tasks of my job
:-) ), but I've met the following annoying problem:
I register the server with the usual

if __name__ == '__main__': win32com.server.register.UseCommandLine(....)

Then I find that I want to add/change/correct something, and I register it
again.
The problem is that Excel persists in calling the OLD server.
At first I believed that it was my fault, since I hadn't changed the
_reg_clsid_ . (more on this later). But even if I changed it, Excel
persisted in calling the old server.
I've found two solutions, both of them ugly:
a) closing and restarting excel (which is way too long, and undesiderable
since maybe I've been writing something on the sheets) or
b) re-naming the .py file and re-running it.
This means that I have a directory full of mySeverXX.py for XX = 1, 2, ...
infinity  :-)

so my questions are:
1) is there a way to refresh the list of servers that excel looks for?
1b) is this in someway connected with the generated .pyc files? by changing
the names I am forcing the interpreter to compile it again, am not I?
2) what happens if I register with the same _reg_clsid_? Is my registry
irreversibly messed up?

This is all for now. I hope you can help me!
thanks in advance,
Francesco

Try to split code to almost static COM and dynamic logic and then 
reload() logic module.

You do not have to create a new clsid every time.  In fact, by doing so,
you are filling your registry with dead clsid entries.

The situation you describe would be the same even if you had written
your component in C++.  For efficiency reasons, an out-of-process COM
server does not automatically die when its last object is freed.  It
will remain in memory until the last calling process ends, or until an
app calls CoFreeUnusedLibraries.  Excel never calls that, so the only
way to free up the existing server instance is to kill Excel.

Remember that the problem you describe only occurs during development,
and we developers are used to being inconvenienced.  Once your server
stabilizes, you will be happy that the instance keeps running, so you
don't have to pay the penalty of invoking the interpreter each time.

No, it's not possible.  CoFreeUnusedLibraries is a Windows API that
Excel must call.  It is not a method in the Excel object model.

Now, THIS problem may be solvable.  Remember that Python supports the
"reload" function that forces it to reload a new version of an imported
module.  It can't change any objects that have already been created, but
it may be able to help you with this specific problem.  You would have
to write your main server in such a way that you could signal it to
reload modules, but that's a solvable problem.

You don't have to expose the fact that your server is forwarding on to
another object.  You can still call server.myPyFunct, and have that
function check to see whether the module has changed, and then call the
real handler.

However, NONE of this will allow to you change the behavior of an object
that already exists.  That's simply impossible.  Once Excel has created
a server object, you're locked in until you free the object.

Subject: [python-win32] VT_UI1 ByRef behavior
Message-ID: <a41467040704281132t3df69a7bq75c2352fe2e5e13d@mail.gmail.com>

I was curious is there a way to prevent an array of VT_UI1's from being
converted to a buffer? Or perhaps a way to modify the file generated from
"makepy" to prevent the conversion?

I am working with a COM module that uses the VT_UI1 and ByRef for a LOT of
its input/output, but it's a bit of a pain to code an extra layer that does
the conversion from an array to a buffer for every function.

Any ideas?

Thanks,
Kevin

Nope, no such facility exists.  Feel free to propose a patch though.

That list is of the type-libraries registered in the system, and by default,
Python has no such typelib.  It is possible to manually create a typelib
that describes your object though - google for other posts by me on this
topic.  For many years, there has been interest in upgrading win32com to
auto-create a typelib - let me know if you are interested in helping with
that...

Because dynamic COM server is a very interesting feature, I think than a 
external (optional) tool for generate TLB is better than the auto-create 
way.

But it's only my personal opinion.

Yeah - it would only be done when explicitly enabled, but the generation of
the typelib itself should be as automatic as possible.  If a decorator
syntax was invented/borrowed to define method signatures and property types,
you would get quite a powerful system.  Having typelibs for your objects is
also important in the .NET world, but sadly I doubt I will have the time to
invent, implement and support a scheme all by my lonesome :)

Well you don't actually say what doesn't work. One point
is that you *might* need to grant your user the
"Act as part of the Operating System" privilege:

   http://tinyurl.com/2s5wfq (MSDN reference)

but you're code's come out rather unformatted in my email
reader so I can't try it out without a fair bit of
rework.
