title: Messages from queues or subqueues
body: <p>I want to create  just a one queue with messages from three different persons, so I just want to take out  the messages from the queue only those which are from person one, I need to modify them and take back to the queue. Someone told me that maybe I could use sub-queues but I'm not sure about how to use that…</p>
  
  <p>This is the method to send to the queue </p>
  
  <pre><code>private void btnEnviar_Click(object sender, EventArgs e) 
  { 
     System.Messaging.Message mn = new System.Messaging.Message();
     Persona p = new Persona()
     { 
       Codigo = 100, 
       Nombre = "Jose Luis Naranjo"
     };
  
     mn.Body = p;
     mn.Label = "Msg: " + c.ToString(); 
     mq.Send(mn)
  }
  </code></pre>
