accessing Microsoft Works document through COM interface in Python

[Puneet Jain]

I am tryin to use Microsoft Works Wordprocessor from Python

After generating the .py module from the type library using makepy
utility, I runt he following commands,
[color=blue][color=green][color=darkred]
>>> from win32com.client import Dispatch
>>> object = Dispatch("Micro softWorks.WordP rocessor.AppCon trol")[/color][/color][/color]

and I get the following error,
Traceback (most recent call last):
File "<interacti ve input>", line 1, in ?
File "C:\Python23\Li b\site-packages\win32c om\client\__ini t__.py",
line 95, in Dispatch
dispatch, userName =
dynamic._GetGoo dDispatchAndUse rName(dispatch, userName,clsctx )
File "C:\Python23\Li b\site-packages\win32c om\client\dynam ic.py",
line 91, in _GetGoodDispatc hAndUserName
return (_GetGoodDispat ch(IDispatch, clsctx), userName)
File "C:\Python23\Li b\site-packages\win32c om\client\dynam ic.py",
line 79, in _GetGoodDispatc h
IDispatch = pythoncom.CoCre ateInstance(IDi spatch, None, clsctx,
pythoncom.IID_I Dispatch)
com_error: (-2147467262, 'No such interface supported', None, None)

It seems like IDispatch is not implemented by Microsoft Works
WordProcessor.

The .py module generated from type library is below

So, I thought I would try to using the native interfaces to get the
correct object,

The generated .py file as a few different IIDs and I am not sure how
to select which one to use. After some trials and errors, I could get
the following to work,
[color=blue][color=green][color=darkred]
>>> from pythoncom import CoCreateInstanc e
>>> object = CoCreateInstanc e(IID('{0FF3639 A-8A82-11D2-B46F-FA00AD000000}') ,[/color][/color][/color]
None, pythoncom.CLSCT X_INPROC_SERVER , pythoncom.IID_I Unknown)

Now I have been trying to use the QueryInterface to get the correct
object and none of the IIDs mentioned in the generated file are
helping.

Appreciate if someone can help me with some pointers here as I think I
am a bit confused.

Thanks in Advance.
