MSMQ active message

I have written a windows service and process messages in a queue and sends and email per each message. I am also writing a windows application that monitors this queue and should determine which message is currently being send. Is there any way to look at a queue externally and determines which message is currently active. This is my winodws service peekcompeleted method:

 private void MyQueue_PeekCompleted(object sender, PeekCompletedEventArgs e)
        {
           
           
            try
            {
             
                incomingmessage = MyQueue.EndReceive(e.AsyncResult);
                incomingmessage.Formatter = new BinaryMessageFormatter();
                sendemail.sendqueuemail(incomingmessage);
                //During this stage when mail is being sent my external
               // application need to know the ID of the message
       
            }
            catch
            {
               

            }
            finally
            {
               // remove the message from the queue if its matches
                 EBTSQueue.Receive();
                 //refresh the Queue
                 EBTSQueue.Refresh();
                // start watching for another message
                EBTSQueue.BeginPeek();
            }
        }
