Chat is one of the most widespread instant messengers, may facilitate the people to carry on the online information exchange at anytime and anywhere, such as the QQ chat software of Tencent Company. This graduation project simulates QQ chat software, develops chat software, which includes the writing, file transfer, audio and video chat and so on.This design development uses the C/S structure, uses the C# programming language to carry on developing this software based on .NET environment. This paper first elaborates the development situation of domestic and foreign chats tool and the development direction nowadays, and has carried on the simple introduction to the development environment and the development language. The demand of multi-function chat software is analyzed in detail, and its plan is provided. Its main functions include the writing, file transfer, audio and video chat and etc. This graduation project mainly realizes the partial functions of multi-function chat software, namely the audio chat, the video chat and so on, which mainly realizes the user registration, the user login, audio chat and video chat. Finally, this design integrates the functions that another schoolmate designs the writing and file transfer, which forms chat software of practical and full functions. This software achieves the anticipated target. Through the running, the test and analysis, it shows, this multi-function chat software is stable, reliable, and has some practical values.Key words: Chat Software; Video Chat; Audio Chat; C/S Structure; QQ Chat Software591 论文网 www.591LW.com目目 录录论文总页数：21 页1 引言.11.1 课题背景.11.2 国内外主要聊天工具的发展状况.11.3 本课题研究的意义.21.4 本文的主要工作.32 需求分析及开发工具.32.1 需求分析.32.2 开发工具.42.2.1 C#语言的介绍.42.2.2 C/S 结构的介绍.52.2.3 开发环境.62.2.4 SQL Server 2000 数据库介绍.73 多功能聊天软件的设计方案.83.1 聊天系统流程的分析与设计.83.2 注册模块的分析与设计.93.3 登录模块的分析与设计.94 语音、视频聊天模块的具体实现.104.1 Video for Windows 简介.104.2 G729.dll 的简介.
