I have written a bit of C# code that I wish to have access to from some
unmanaged C++ code I am writing.  I have written a COM interface for the
classes and their methods, but I cannot manage to get access to them in the
C++ code.  I am doing something wrong, but I do not know what.

I have the C# COM objects broken down into a .tlb file.

Given this file, what do I need to do in C++ to gain access to the classes?

The class is called XXXPacket, and the interface is IXXXPacket.  The method
is Populate.

Any help would be appreciated.

thanks
