The events are used to notify an application of the actual changes of the collection of participants in the source session. These events occur as the results of the AddParticipant or RemoveParticipant request made by either this application instance or a client instance used by a remote participant. This is a dispinterface. Its members define the event handlers for the events raised by an IUccSessionParticipantCollection object. To catch the events, a UCC API client must implement these event handlers and advise the event source of the implementation if it is interested in receiving the events. To prevent memory leaks, the client should unadvise the events when it is no longer interested in the events.

The following example is a partial class that inherits UserControl and provides instant messaging functionality. The partial class implements the _IUccSessionParticipantCollectionEvents interface and handles those events.

public partial class UserControl1 : UserControl, 
    _IUccSessionParticipantCollectionEvents
{
    void _IUccSessionParticipantCollectionEvents.OnParticipantAdded(
            IUccSession pEventSource, 
            UccSessionParticipantCollectionEvent pEventData)
    {
    }

    void _IUccSessionParticipantCollectionEvents.OnParticipantRemoved(
        IUccSession pEventSource, 
        UccApi.UccSessionParticipantCollectionEvent pEventData)
    {
    }
}
