Thomas, thanks for your help. Everything seemed to work except when I
needed to pass my com object to another com function to receive
callbacks
> > o=myComObjClass()

The other dispatched com object was created using win32com, and other
functions of it work fine. However, this specific function needs to
be called with a com object implementing the interface as one of the
inputs, and then its functions will be called as callbacks. The error
I get when I pass o to this function is
ValueError: argument is not a COM object
Do you have any suggestions? Thanks again for your help
