The magic you need can be found at:

This file is what I use for eucom.  COM objects are really just C++ 
objects that follow certain conventions.

The hard part is dealing with the name decoration.  And if your C++ is 
built using MSVC, it's probably using a slightly different calling 
convention, where the 'this' pointer is passed in ecx, rather than
on the stack.
