INmCallNotify

  • Article

INmCallNotify is the event sink for INmCall. The NetMeeting 3 run time calls INmCallNotify methods when certain events are triggered that specifically concern incoming and outgoing calls.

When to Implement

Implement INmCallNotify in NetMeeting client applications to process event notifications from the NetMeeting run time. For example, the INmCallNotify::StateChanged method is notified when the state of a call has changed. The client application implementation of this method could provide a display to the user for each of these state changes when they occur.

The application must be in control of the NetMeeting UI (it must have successfully initialized with NM_INIT_CONTROL) for it to be notified of incoming calls.

When to Use

You do not normally call INmCallNotify methods directly. The NetMeeting run time calls these methods when certain events are triggered by calls to INmCall methods.
