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;

thanks for your replay..
but if i made the suggested cast i get
../pyThinkdesign.cpp(59) : error C2259: 'IUnknown' : cannot instantiate

due to following members:
