Sending messages to MSMQ using a WCF service

Question

I've created a WCF service to send a message to an MSMQ, I can get it to run and it looks like the message was sent but when looking at the queue it's not there. I've verified and the queue is not a transactional queue. Security is open so that everyone can send messages but I'm wondering if there are other places to set security? Here is my code I'm using.

Dim mq As MessageQueue
Dim msg As Message
Dim queueName As String = "webdevbvm.labsafety.com\emailsubscriptions"

Try
   msg = New Message("Test")
   msg.Priority = MessagePriority.Highest

   If (MessageQueue.Exists(queueName)) Then
       mq = New MessageQueue(queueName)
   msg.ResponseQueue = mq
   msg.UseJournalQueue = True
   msg.Label = "Test Message"
   msg.Body = "This is only a test"
   mq.Send(msg)
   Console.WriteLine("Message sent.")
   End If
Catch ex As MessageQueueException
   Console.WriteLine("MSMQ Error: " + ex.ToString())
Catch ex As Exception
   Console.WriteLine("Error: " + ex.ToString())
Finally
   mq.Close()
End Try

I get no errors but I do see the messages in my outgoing queue from the machine that is running the program. It shows the queue exists and if I change the queue name to one that doesn't exist it doesn't go into the IF statement so I know it's seeing the queue just not sending the file. If it helps I'm running the program locally on a laptop and the queue it's sending too is on a Windows 2003 server.

That doesn't look like a WCF service to me - seems you're using the base System.Net.Messaging API to send message to your queue....

Check out some of these link to see how to use WCF to send messages to MSMQ:

Thanks marc for your response but I figured out what needed to be done. Basially I was using the wrong queue name. I didn't have "FormatName:DIRECT=OS:" in front of the queue name. Once I put that it was good to go. thanks again.
