Checking for an empty queue in Service Broker

I need to write code that pulls from a queue until the queue is empty.  The name of my pulling procedure is MsgIncoming_Queue_Receive and it works fine when called one at a time.

What I need help with is the condition of the loop.  How can I test outside the service broker system whether the queue is empty?  In fact this is supposed to be done within coldFusion code.  

The psuedo code is shown below:

while (! emptyQueue) {
    MsgIncoming_Queue_Receive
}

Service broker queues are implemented as hidden tables so you cannot use standard T-SQL queries to update them but with each queue there is a read-only view associated so you can use standard SELECT statement to see what is in the queue.

so to see how many messages you have in the queue all you have to do is:

select count(*) from yourQueueNameHere
