Quite some com objects do not have a type library; probably those that are only
supposed (by MS) to be used by C++ code.

Sometimes an .idl file can be found somewhere in the SDKs which you can
compile into a .tlb file, sometimes not.

Sometimes someone who wants to use the object from VB writes an idl file
and compiles a typelib (but you could also try it yourself, maybe).
With a little googling I found a zip-file containing such a library:

http://www.msjogren.net/dotnet/eng/samples/vb6_progdlg.asp

However, this typelib would not help if you are using pywin32; comtypes
would probably be able to use it - I haven't tried it myself.
