Location: programming\c++\cvs\polylib

Status: Working: Needs a few extra features

This is a set of classes that supports client/server connections to a master server to allow client programs to easily find servers.
Classes

CMasterServer - Only used in the master server application. Accepts client and server connections and sends clients a list of servers.
CNetServer - Notifies a master server of game server.
CNetClient - Connects to the master server to find game servers.

SERVER_CONNECTING: Following the application connection steps

SERVER_ERROR

Application Connection Steps (CNetClient)

Connect to polyart to get master server IP
Connect to master server to get server list
Open dialog to allow user to select server
Connect to selected server

Several classes are needed

- Register Server
- Accept new clients
- Unregister Server
Client Tool class: CNetClient - Find servers to connect to

Server GUI template

Location: programming\c++\ServerGUI
Files: ServerGUI.cpp,MasterServer.cpp

Status: Working: Needs a few extra features
This template will be used for both single server and the master server. It will contain a tray icon that will be green and turn red when there is a connection. Right clicking the icon will bring up a dialog box containing information. Right clicking the server will provide an exit option followed by an info option. As a template, it should be designed so that new server types can be easily plugged into it.
