Intercept events fired by a C# Com component in a unmanaged C++ client

Hi all.
 
I've a C# Com DLL being used by a C++ client (not C++/CLI).
 
Everything works fine, except that I need to catch on the client the events fired on the delegates on the C# part.
 
I've found some samples of this using VB6, but no code using C++.
 
My client is a VC++ Console application (no CLI, no ATL, no MFC...)
 
Any hints about? Is that possible?
 
TIA
Nilo
