You are just getting a compile-time error, right? That’s because the smart
pointer wrapper (CComPtr)will only accept a pointer that actually derives from
the type it is wrapping. In this case, that’s not so. You will probably have
to force the pointer to be an IUnknown* before you can wrap it in a smart
pointer.
pUnk = (IUnknown*)pyApplication;
