中文摘要: 详细介绍了屏幕监控软件的设计思路和开发技术。使用WinSock API 接口和MFC 网络编程技术，系统采用C/S 模式，基于UDP 协议进行通信，客户机端(Client)通过Winsock 发送抓取监控屏幕的指令，服务器端(Server)接收服务器端传来的指令抓取屏幕，并将其转化为JPEG 数据流，向服务器端传输图像数据流。实验结果表明，该方法能高质量实时的对计算机屏幕进行监控。

Abstract:This paper describes the design of the screen monitoring software ideas and development techniques. With the WinSock API interface and MFC Internet programming technology, the system uses C/S model, based on UDP protocol for communication. The client side (Client) sends commands to crawl the screen Control through the Winsock. The server side (Server) receive capture screen instructions from server-side, and translate them into JPEG data streams, the server-side image data stream. Experimental results show that the method can easily realize the computer screen monitoring.
