Ok, I downloaded that project, and stripped out the TLB. I then got comtypes
and was able to use comtypes.client.GetModule to generate the typelib wrapper
module for it:
>>> GetModule("progdlg.tlb")
<module 'comtypes.gen.VBProgressDialog' from
'C:\Python25\lib\site-packages\comtypes\gen\_2F2719A2_83CC_11D3_A08C_0040F6A4BFEC_0_1_1.pyc'>
>>> import comtypes.gen.VBProgressDialog
Now I can't seem to figure out what to do. There are three classes generated:
class IOleWindow(comtypes.IUnknown)
class IProgressDialog(comtypes.IUnknown)
class ProgressDialog(comtypes.CoClass)
Instantiating IProgressDialog() seems to give me an instance that has the
methods that I'm looking for (at least they show up in Idle as callable
methods), but when I try to call one I get the following message:
Traceback (most recent call last):
File "<pyshell#20>", line 1, in <module>
b.SetTitle('test')
TypeError: Expected a COM this pointer as first argument
Sorry to be so dense, I'm still learning the COM stuff.
Thanks in advance.

Test program:
import comtypes.client.GetModule
GetModule('progdlg.tlb')
import comtypes.gen.VBProgressDialog
ci=comtypes.gen.VBProgressDialog
a=ci.ProgressDialog()
a.SetTitle('test')
