The authentication level of a queue determines whether the queue accepts only authenticated messages. By default, a queue accepts both authenticated and non-authenticated messages.
|If your application does not have MQSEC_GET_QUEUE_PROPERTIES access rights for the queue, an MQ_ERROR_ACCESS_DENIED error is returned to MSMQQueueInfo.Refresh.|
Declare the MSMQQueueInfovariable for the queue.
Obtain an MSMQQueueInfoobject.
(Optional) Call MSMQQueueInfo.Refreshif other applications may have changed the authentication level of the queue.
Use MSMQQueueInfo.Authenticateas needed.
