+Description
+===========
+  The DataRelay is similar to SimplePeer but differs by sending a single 
+  target (or everyone) a packet of data with options specified in the 
+  dialog's UI.

+User's Guide
+============
+  Host or connect to a session in the same manner as explained in SimplePeer.
+  When the main dialog appears select the target, size, rate, and timeout values.
+  Then click "Push to Send". This will send a packet of data to the target as
+  the rate specified with the specified size.
+
+Programming Notes
+=================
+  The DataRelay sample is very similar in form to the SimplePeer sample.  For 
+  detailed programming notes on the basics this sample, refer to Programming 
+  Notes section of the SimplePeer sample.
+
+  The DataRelay differs by sending a single target (or everyone) a packet of 
+  data with options specified in the dialog's UI. 
+
+  When the "Push to Send" button is clicked, a timer goes off every number of 
+  ms according to the UI and sends data.
+
+  * When the timer notices it's time to send data, it does the following:
+	1. Creates a byte array with the options specified in the UI.
+	2. DirectPlay8Peer.SendTo is called passing in the byte array.  We 
+           call SendTo with the flags DPNSEND_NOLOOPBACK.  DPNSEND_NOLOOPBACK tells
+	   DirectPlay to not to send the buffer to us.
+	
+  * Handle DirectPlay system messages.  See implemented DirectPlay8Event interfaces
+        The DataRelay handles the typical messages as described in the 
+        SimplePeer programming notes, and in addition:
+        
+        - Upon Receive event
+            1. Gets the message type from the received byte array.
+            2. It then selects off the message type. 
+            3. If its a MSG_GamePacket, then it adds the data to a collection,
+               where a timer will notice the data and process it.  This is important
+               so the DirectPlay threads stay working atfull speed.
+
+        - Upon DPN_MSGID_SEND_COMPLETE
+            1. It checks the dpnotify.hResultCode for DPNERR_TIMEDOUT.
+            2. If this occurs then it updates the UI.
