Strange Python COM behaviour

[a_bogdan_marinescu]

Hello all,

I'm trying to do some COM automation from Python (using Mark
Hammond's Win32 extensions, of course) and I'm getting some very
strange errors. Specifically, I try to use a COM object that supports
events, and I'm instantiating it like this:

eventobj = win32com.client .DispatchWithEv ents( crtthread,
DebuggerThreadE vents )

When I try to do this, I get the following error:

....
File "d:\work\script s\automation\au tobuild.py", line 106, in
execute_one_fil e
eventobj = win32com.client .DispatchWithEv ents( crtthread,
DebuggerThreadE vents )
File "C:\Python23\li b\site-packages\win32c om\client\__ini t__.py",
line 264, in DispatchWithEve nts
result_class = new.classobj("C OMEventClass", (disp_class,
events_class, user_event_clas s), {"__setattr_ _" : _event_setattr_ })
TypeError: str() takes at most 1 argument (3 given)

It seems that events_class's type is str ( as returned by
getevents() function in __init__.py file from win32com/Client
directory) instead of 'classobj' as it is supposed to be. event_class
is actually a simple string showing a CLSID. I'm new to COM and I
can't understand why this is happening. Please help me if you can.
Regards,

It looks to me as if this error could occur if the event interface you
are trying to implement is not based on IDispatch. It looks like a bug
in win32com - what is the object you are trying to use?
