I try to change the AudioDecoder coclass to implement also the

coclass AudioDecoder

interface IAudioRecorder;
[default] interface IAudioDecoder;

[default, source] dispinterface _IAudioDecoderEvents;
};
But, now? How can I code for this new design? I try to add a new
CONNECTION_POINT_ENTRY:
BEGIN_CONNECTION_POINT_MAP(CAudioDecoder)
CONNECTION_POINT_ENTRY(__uuidof(_IAudioDecoderEvents))
CONNECTION_POINT_ENTRY(__uuidof(_IAudioRecorderEvents))
END_CONNECTION_POINT_MAP()
You also need to derive from two proxies (should be named something like =
_IAudioDecoderEventsCP and _IAudioRecorderEventsCP). You probably =
already derive from one - just add the other.
