[python-win32] COM server AddIn

[Johannes Brunen]

Hi Mark,

now I have made some progress! Using the win32traceutil worked well.

However the real essential part was the addition of the _typelib_guid_ 
variable
to the server class. Below, I have added the working example. Could you
confirm that this is the proper way of using the modules?

Two questions remains:
1.) The following code line seems to be unnecessary. The AddIn sever works 
without it as well. What is
the idea for this line? Do I need it?
universal.RegisterInterfaces('{9C3BB401-114D-11D4-AC72-00105A4925FC}', 0, 1, 
2, ['ICADdyAddIn'])

2.) Debugging the server gives me now the following lines in the trace debug 
window, which I don't understand. Can you explain what their
meaning is?
Object with win32trace dispatcher created (object=None)
in <Addin1.AddIn1 instance at 0x1F8B9DC8>._QueryInterface_ with unsupported 
IID IMarshal ({00000003-0000-0000-C000-000000000046})

Thank you very much for your supporting help and time!!
