SetMessageListener2 method

Sets a MessageListener2 delegate to receive QAnywhere messages asynchronously. See MessageListener2 delegate.

Syntax
Visual Basic
Public Sub SetMessageListener2( _
   ByVal address As String, _
   ByVal listener As MessageListener2 _
)
C#
public void SetMessageListener2(
   string  address,
   MessageListener2 listener
);
Parameters
  • address   The address of messages.

  • listener   The listener to register.

Remarks

Use this method to receive message asynchronously.

MessageListener2 delegate accepts QAManagerBase and QAMessage parameters.

The SetMessageListener2 address parameter specifies a local queue name used to receive the message. You can only have one listener delegate assigned to a given queue. You may set an ExceptionListener2 and a MessageListener2 for a given address, but you must be consistent with the Listener/Listener2 delegates. That is, you cannot set an ExceptionListener and a MessageListener2, nor an ExceptionListener2 and a MessageListener, for the same address.

If you want to listen for QAnywhere system messages, including push notifications and network status changes, specify system as the queue name.
