GetMessageBySelector method

Returns the next available QAMessage sent to the specified address that satisfies the given selector.

Syntax
Visual Basic
Public Function GetMessageBySelector( _
   ByVal address As String, _
   ByVal selector As String _
) As QAMessage
C#
public QAMessage GetMessageBySelector(
   string  address,
   string  selector
);
Parameters
  • address   This address specifies the queue name used by the QAnywhere client to receive messages.

  • selector   The selector.

Return value

The next QAMessage, or null if no message is available.

Remarks

The address parameter specifies a local queue name. The address can be in the form store-id\queue-name or queue-name.

If there is no message available, this call blocks indefinitely until a message is available. Use this method to receive messages synchronously.

For more information about receiving messages asynchronously (using a message event handler), see Receiving messages asynchronously.
