I've been looking through the type library in dx7vb.dll and the
information in ddraw.h.  The DX7 type library for Visual Basic
outlines a completely different objects than the C header files
for DX7.  Certain methods exist in one, but not in the other.
Some methods exist in both the C and the VB version, but take
different parameters.

Since I need to interface with Quicktime and since Quicktime is expecting the C++ versions of the COM objects, I think I'm
out of luck with regards to the dx7vb.dll.  If I didn't need to use 
Quicktime then dx7vb.dll would be fine, but since I do, I guess 
I get to learn about turning a C header file into a type library.

You doubts are correct.

Anyway, thanks for your replies; they've been helpful.  And thanks
especially for GNATCOM.  Writing bindings to DirectX by hand would
almost be enough to make me take up pig farming for a living.

A new slogan for GNATCOM?  "Enough to keep you away from pig farming."  :-)

I just remembered that VC (I think the DX7 SDK also) ships with the actual
IDL files for DX that are used to generate the C headers. You can modify
those to produce a type library (by adding a library section) and use that
type library.
