双线程处理Socket，一个线程负责发一个负责 ，TCPDemo在具体实现时，设计了一个CTCPListener类专门用于服务器对特定TCP端口的侦听。另外，设计了一个CStreamSocket类专门用于TCP数据的传输。CStreamSocket作为基类，服务器程序从它派生出另一个类CSocketSender专门用于数据的发送，客户机程序从它派生出CSocketReceiver类专门用于数据的接收。这些类的继承结构如图3

本系统属于小型的局域网监控系统，可以对某一台计算机进行屏幕监控，本系统主要实现以下功能：  系统采用人机交互的方式，界面美观友好。  屏幕信息需要时时显示，网络延时不能大于1秒。  服务器端可以随时运行，只要客户端运行，就能够显示屏幕信息。  系统运行时占用内存不能大于10MB，以免影响系统性能。  客户端运行时需要隐藏显示窗口，起其感觉不到在运行。 -This system belongs to a small local area network monitoring system that can carry out the screen of a computer monitor, this system is mainly to achieve the following features:  system uses human-computer interaction approach, friendly and beautiful interface.  screen displays information needs from time to time, the network delay can not exceed 1 second.  server-side ready to run, as long as the client is running, you can display on-screen information.  memory for the system is running can not be larger than 10MB, so as not to affect system performance.  the client run-time to hide the display window, from the feel running.
