SetMessageListener2 method Next Page

SetMessageListenerBySelector method

Sets a MessageListener delegate delegate to receive QAnywhere messages asynchronously, with a message selector.


Visual Basic
Public Sub SetMessageListenerBySelector( _
ByVal address As String, _
ByVal selector As String, _
ByVal listener As MessageListener _

public void SetMessageListenerBySelector(
string address,
string selector,
MessageListener listener


Use this method to receive message asynchronously.

MessageListener delegate accepts a single QAMessage parameter.

The SetMessageListener address parameter specifies a local queue name used to receive the message. You can only have one listener delegate assigned to a given queue. The selector parameter specifies a selector to be used to filter the messages to be received on the given address. You may set an ExceptionListener and a MessageListener 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.
