Add a Participant to an Existing Session

  • Article

The following code example demonstrates how to add a participant to an existing MIM session. The operations in the Initialize RTC and Create a Multiparty IM Session and Add a Participant code examples must be performed before using this example.

Note  This example does not contain error checking or releases appropriate for real code.

C++ Code Example

IRTCParticipant   *pIRTCParty   = NULL;
BSTR              bstrDestURI   = SysAllocString(L"someone2@microsoft.com");

// Add the participant.
hr = pIRTCSession->AddParticipant(bstrDestURI,
                                  NULL,
                                  &pParty);

// If (hr != S_OK), process the error here. 

// Wait for the RTCE_PARTICIPANT_STATE_CHANGE event of 
// type RTCPS_CONNECTED, indicating that the participant 
// has successfully joined the session.

Visual Basic Code Example

Dim objSession As IRTCSession
Dim objParticipant As IRTCParticipant
Dim strDestURI As String      '(for example, someone2@microsoft.com)
Dim strDestName As String     '(for example, Jeff Smith)

'Add a participant to the IM session.
Set objParticipant = objSession.AddParticipant(strDestURI, _
                                               strDestName)

' If (Err.Number), process the error here. 

' Wait for the RTCE_PARTICIPANT_STATE_CHANGE event of 
' type RTCPS_CONNECTED, indicating that the participant 
' has been successfully added to the session.
