Meanwhile, more and more problems come into being. For example, during the course, teacher must think about how to organize the interactive between teacher and student in teaching? Teachers are often not able to know what problems the students are disturbing. By means of this software (or tool), called Multi-Media Education Control System (abbrev. MECS), we might organize a lesson in computer network, and properly control the thinking of students and allow student to take part in the procedure of teaching. After the aid of this software, teacher might organize the theoretic and practice teaching as a whole.“The multi-media teaching control system represents a kind of brand-new teaching method. By making use of this software, which basing on the existing computer network and equipments, teacher can supervise and control the students computer, broadcast multi-media information, and help students to master some software. This system shows us an advanced thought of digit and network technology, break down the limit of time and area. It not only carries out the traditional classroom teaching between teacher and students, but also matches the characteristics of computer teaching, which is said relaxed and interactive. It is a great progress, and break through the traditional teaching method.Keywords: Multi-Media Network technology Education System目录摘 要 -Abstract-II第一章 前言 -11.1、提出问题 -11.2、相关概念定义 -11.2.1、完成端口(CompletionPort) -5 -11.2.2、组播(MultiCast) -6 -11.2.3、位图（Bitmap） -7 -21.2.4、套接字(Socket) -21.2.5、控制命令(Control Instruction) -21.2.6、数据包(Data Package) -2第二章 需求分析 -42.1、引言 -42.2、系统功能概述 -42.3、系统的体系结构 -42.4、数据流图 -62.5、数据字典 -72.6、系统模块划分 -8第三章 总体设计 -93.1、软件的设计与规划 -93.2、软件设计的方法与内容 -93.3、系统功能结构图 -9第四章 详细设计 -114.1 基础网络通讯模块的设计 -114.1.1 服务器端 IOCP 模型函数介绍 -114.1.2 服务器端 IOCP 调用流程图 -134.1.3 完成端口的初始化 -134.1.4 完成端口收发数据 -144.1.5 完成端口主线程 -154.1.6 客户端基础通讯程序图 -174.1.7 客户端初始化 -174.2 组播设计 -184.2.1 组播地址的选择 -184.2.2 组播调用流程图 -194.2.3 组播初始化 -194.3 屏幕捕捉的设计 -204.3.1 捕捉信息的结构 -204.3.2 捕捉屏幕流程图 -214.3.3 屏幕位图显示流程图 -214.3.4 屏幕捕捉及发送流程图 -22第五章 编码 -235.1 基础网络通讯模块主要编码的实现 -235.1.1 服务器端初始化 -235.1.2 服务器端主线程 -255.1.3 服务器端子线程 -275.1.4 服务器端收发数据的实现 -275.1.5 客户端初始化 -295.1.6 客户端收发数据的实现 -
