Powerpoint as a COM object used from C. (Missing headers/documentation)

[Martin Tilsted]

How do I call the Powerpoint COM object from a C program, using the
win32 api?.

Right now I am using the CoCreateInstance, to connect to Powerpoint and
get a COM object which is working. So now I got an IUnknown COM object.

But that's not really usefull so I want to call QueryInterface to find
out which interfaces Powerpoint supports. And here is the problem.

QueryInterface want a REFIID(That is: A iid/guid) but how do I find the
iid for the COM classes that powerpoint supports?

For the rest of windows there exists headerfiles which contains the
needed iid, but I have not been able to find any for powerpoint.


And I really don't think I should even have to call QueryInterface,
because normally all this is wrapped in auto generated functions.

So my question is: Where are the headerfiles for Powerpoint, which is
needed to use powerpoint as a COM object?

Since nobody here knows the answer, do there exists a newsgroup for
users developing plugins for Powerpoint?

It says

"How To Build an Office COM Add-in by Using Visual Basic .NET"

I need to call the com methods in powerpoint, using C(Or C++), while
using only the Win32 api.

I can't use the .net framework, mfc, atl or similary libraries due to
link issues.
