[python-win32] Problems with automation in newer versions of win32all

[greg Landrum]

Upon upgrading to Python 2.3 and installing the most recent version of win32all (build 163), some frequently used COM client code ceased to function.

The exception I'm seeing is:
  File "chemdraw.py", line 89, in CDXConvert
    theObjs.SetData(inFormat,inData)
  File "c:\Python23\Lib\site-packages\win32com\gen_py\5F646AAB-3B56-48D2-904C-A68D7989C251x0x7x0.py", line 416, in SetData
    return self._oleobj_.InvokeTypes(21, LCID, 4, (24, 0), ((12, 17), (12, 17),(12, 17), (12, 17), (12, 1)),dataType, resolution, Width, Height, arg4)
pywintypes.com_error: (-2147352567, 'Exception occurred.', (0, None, None, None, 0, -2147352571), 5)

The definition of SetData() (from the auto-generated file) looks like this:
	# The method SetData is actually a property, but must be used as a method to correctly pass the arguments
	def SetData(self, dataType=defaultNamedNotOptArg, resolution=defaultNamedNotOptArg, Width=defaultNamedNotOptArg, Height=defaultNamedNotOptArg, arg4=defaultUnnamedArg):
		"""Returns the data of the objects."""
		return self._oleobj_.InvokeTypes(21, LCID, 4, (24, 0), ((12, 17), (12, 17), (12, 17), (12, 17), (12, 1)),dataType, resolution, Width, Height, arg4)

SetData() is being called with proper arguments (2 strings)

I first encountered this problem about  a year ago using Python 2.2 and discovered that it started at build 150 of win32all (my earlier message about this same problem can be found at URL: http://aspn.activestate.com/ASPN/Mail/Message/Python-win32/1686417 ).  My "solution" then was to just stick with using build 148.  Unfortunately, now that I've switched to Python 2.3, this is no longer an option.

This is a serious problem for us, I would be very grateful for any solutions or work-arounds.

Thanks
