Is there an event raised when a message is dequeued from an MSMQ queue?

Question

I'm trying to get a level of management information available in a system which is being driven by MSMQ queues. I want to know if there's an event which can be listened to, to know when a message is successfully dequeued from a queue.

Ideally the event would be consumed via a .NET application.

This would allow me to keep track of the volume of messages passing through a queue without implementing logic into the receiving service endpoint and enable common mechanisms regardless of receiver (which will be BizTalk in some cases).

No, just raise your own event when you dequeue a message. If this is another app then double-no, events don't work across process boundaries. — Hans Passant
@Hans Passant, BizTalk won't raise an event when it's reading from a message queue. The COM events should work cross-process (msdn.microsoft.com/en-us/library/windows/desktop/…), but I don't have the experience to know if the right event for me is available. — Paul Turner

The MessageQueue.BeginReceive asynchronous method raises the ReceivedCompleted event when a message has been sucessfully received (and therefore removed from a queue).

Is there an event raised when a message is dequeued from an MSMQ queue?
