Yes, I found out eventually that it was Document I should have had here, not
IFoo (as in "IFoo.Document").

The clsid part was no problem; CLSIDFromProg() gave me that. CCI /also/
needs an IID of the interface to retrieve, so that is where _uuidof(xxx)
came in - I just got confused about what should have got in it, since it
really isn't clear from the .tlh file (unless you know what you're looking
at).

It was a pure IDispatch interface.
