Hi,

Once I faced a similar situation. I found the error using the re-implementation
of the functions (using CreateStreamOnHGlobal, CoMarshalInterface and
CoUnmarshalInterface). This way I retrieved more information. (Just don't forget
to seek the stream to the start when unmarshaling - I did it. :-()

HTH,
Csaba
