+Description
+===========
+  LobbyClient is a simple lobby client.  It displays all registered DirectPlay 
+  applications on the local system.  It allows the 
+  user to launch one or more of these applications using a chosen 
+  service provider.  A launched lobbied application may be told to either 
+  join or host a game.

+
+User's Guide
+============
+  Choose launch settings from dialog, and click "Launch App".  The
+  lobby client will launch the app selected based on the settings in the UI.
+  The active connections list will display the handle to all the current 
+  lobbied applications.  Clicking on "Send Message" will send a lobby message
+  to the lobbied application.  This done mainly for demonstration purposes.  A more
+  complex lobby client may want to use this functionality in a more meaningful way
+  by passing a message that the lobbied application responds to.
+
+Programming Notes
+=================
+    * Initialize DirectPlay. See InitDirectPlay()
+        1. Init COM with CoInitialize()
+        2. Create a IIDirectPlay8Peer with CoCreateInstance()
+        3. Call IDirectPlay8Peer::Initialize to tell the interface about our 
+           message handler
+        4. Create a IDirectPlay8LobbyClient with CoCreateInstance()
+        5. Call IDirectPlay8LobbyClient::Initialize to tell the interface 
+           about our lobby message handler
+        
+
+    * Initialize dialog box. See OnInitDialog()
+        1. Enumerate the registered lobbied applications and display them
+           in the dialog listbox.  See EnumRegisteredApplications()
+        2. Enumerate the DirectPlay service providers and display them
+           in the dialog listbox.  See EnumServiceProviders()
+        3. Whenever a new service provider is selected (and upon init) then
+           enumerate the service provider's adapters.  See EnumAdapters().
+
+    * When "Launch App" button is clicked.  See LaunchApp()
+        1. Fill out a DPL_CONNECT_INFO struct.  This is complex
+           since it contains the host and device addresses as well as
+           the DPN_APPLICATION_DESC.  See LaunchApp() and 
+           AllocAndInitConnectSettings().
+        2. Call IDirectPlay8LobbyClient::ConnectApplication() passing in
+           the DPL_CONNECT_INFO struct.
+        3. Free the DPL_CONNECT_INFO struct. This is also complex since this 
+           struct has a number of DPlay addresses.  See FreeConnectSettings().
+        
+   * Upon DirectPlay Lobby messages. See DirectPlayLobbyMessageHandler()
+        - Upon DPL_MSGID_DISCONNECT:
+            pDisconnectMsg->hDisconnectId will contain the handle of the 
+            lobbied application that was disconnected, and 
+            pDisconnectMsg->hrReason will be the reason.  This simple 
+            sample just pops up a message box.
+        - Upon DPL_MSGID_RECEIVE:
+            The lobbied application sent the client data.  This simple sample 
+            doesn't respond to any message.
+        - Upon DPL_MSGID_SESSION_STATUS:
+            A lobbied application has changed its status.  pStatusMsg->hSender 
+            will one of several predefined status codes.  This simple
+            sample just updated the UI showing that the lobby status has
+            updated, however more complex lobby clients many want to take action.
+        - Upon DPL_MSGID_CONNECTION_SETTINGS:
+            A lobbied application has changed its connection settings.  This
+            simple lobby client doesn't take any action however, more complex
+            clients may want to take action.
+            
+   * When "Send Message" is clicked. See SendMsgToApp()
+        Call IDirectPlay8LobbyClient::Send() with the handle of the 
+        lobbied application to send the message to, and the buffer to send.
+        
+   * When "Disconnect" is clicked. See DisconnectFromApp()
+        Call IDirectPlay8LobbyClient::ReleaseApplication() with the handle of 
+        lobbied application to disconnect from.
+
