Michael,

please use text emails instead of html when posting to this list, it is
much easier to read.

To answer your question:  There are basically 3 possibilities, with
increasing difficulty:

- Find a typelibary somewhere on the internet; the VB guys also need
  typelibs to use com interfaces
- Compile one yourself from some IDL files in some MS SDKs, or write
  the idl code yourself and compile it
- Describe the interface in comtypes without using a typelib

It looks like a typelib (even with source) for IOleObject is available on this site:

http://www.vbaccelerator.com/typelib.htm

If you use these 'unofficial' typelibs I would recommend to move the generated modules
out of the comtypes\gen directory.
