Dear All,

thanks for looking in to this.

I am implementating IConnectionPointContainer for myClass, I have simply publically derived it from IConnectionPointContainer and other interfaces. declared and defined IConnectionPointContainer Interface methods in myClass, implement QueryInterface for myClass which is returning this pointer when client asks for IConnectionPointContainer Interface. up to this it works fine. but at client side it receives NULL pointer with error 80004002 not implemented.

is there anything missing , here I am treating IConnectionPointContainer as simple Interface,

why COM Internal mechanism dosen't forwerd interface pointer to client. and instead sends 80004002 error.

Thanks again.
