Retrieving messages off a queue

Reading a message off the queue may be requested using one of two modes. PeekLock, which is the default mode, reads the message of the queue and places a lock on the read message. This makes the message invisible to other consumers of the queue. The message will reappear on the queue if the consumer does not issue a Complete command within the specified VisibilityTimeout period. The message can also reappear if the consumer calls the Abandon method. This type of processing is ideal for when guaranteed processing of a message is mandatory.

The following process flow describes reading a message from the queue using the PeekLock method. Note the two scenarios when a message is placed on the dead-letter queue. First one is when the message is not read within the specified TTL period, and the second scenario is when the de-queuing count equals zero.
