INmChannelNotify
INmChannelNotify is the event sink for INmChannel. The NetMeeting 3 run time calls INmChannelNotify methods when certain events are triggered that specifically concern channel communication. All other channel notification interfaces (INmChannelAudioNotify, INmChannelVideoNotify, INmChannelDataNotify, INmChannelFtNotify, and INmChannelAppShareNotify) inherit from this interface.
When to Implement
Implement INmChannelNotify in NetMeeting client applications to process event notifications from the NetMeeting run time. For example, the INmChannelNotify::MemberChanged method is called when a member joins, leaves, or changes the data-handling capabilities for a channel.
The application must be in control of the NetMeeting UI — that is, the application must have initialized successfully with NM_INIT_CONTROL — in order to be notified of channel changes.
When to Use
You do not normally call INmChannelNotify methods directly. The NetMeeting run time calls these methods when certain events are triggered by calls to INmChannel methods.
