Syntax

'Declaration
Sub OnComposing ( _
    pEventSource As UccInstantMessagingSessionParticipant, _
    pEventData As UccInstantMessagingComposingEvent _
)

void OnComposing (
    UccInstantMessagingSessionParticipant pEventSource,
    UccInstantMessagingComposingEvent pEventData
)

void OnComposing (
    UccInstantMessagingSessionParticipant^ pEventSource, 
    UccInstantMessagingComposingEvent^ pEventData
)

void OnComposing (
    UccInstantMessagingSessionParticipant pEventSource, 
    UccInstantMessagingComposingEvent pEventData
)

function OnComposing (
    pEventSource : UccInstantMessagingSessionParticipant, 
    pEventData : UccInstantMessagingComposingEvent
)

Parameters

Remarks

In order to raise the OnComposing event on a remote partcipant endpoint, the local participant must call StartComposing on the IUccInstantMessagingSession instance. After a participant has called into StartComposing, that participant is considered to be composing until a call into StopComposing is made. After a participant has called into StopComposing, the other session participant receives the OnIdle event that indicates the composing participant has stopped composing.

Win32 COM/C++ Syntax

HRESULT OnComposing
(
   IUccInstantMessagingSessionParticipant* pEventSource,
   IUccInstantMessagingComposingEvent* pEventData
);

Note

In a Win32 application, the return value of a method or property is always an HRESULT value indicating the status of the call to the interface member. Any result of the operation is returned as a parameter marked with the [out, retval] attribute. In contrast, in a .NET application the HRESULT value indicating an error condition is returned as a COM exception and the [out, retval] parameter becomes the return value. For the UCC API-defined HRESULT values, see Trace and Handle Errors in Unified Communications Client API .

Example

The following example displays a message indicating a remote instant messaging session participant has called StartComposing.

/// <summary>
/// raised when a remote session participant is composing
/// </summary>
/// <param name="pEventSource">IUccInstantMessagingSessionParticipant remote participant</param>
/// <param name="pEventData">IUccInstantMessagingComposingEvent event data</param>
void _IUccInstantMessagingSessionParticipantEvents.OnComposing(
    UccInstantMessagingSessionParticipant pEventSource, 
    UccInstantMessagingComposingEvent pEventData)
{
    Console.WriteLine(
        pEventData.ParticipantEndpoint.Participant.Uri.User + 
        " is composing " + 
        pEventSource.ComposingContentType);
    
}
