随着
计算机的普及和快速发展,计算机
网络已经渗入到我们的日常生活中,而网络聊天
系统的使用最为频繁。网络聊天系统可以使人在很远的距离内进行聊天,甚至包括语音和视频的,通过网络聊天系统,不仅可以联络人们之间的感情,增进人们之间的友谊,而且还使这个世界越来越小,同时也越来越方便。因此,研究网络聊天系统是十分有意义的。
该聊天系统是一个基于C/S架构(即客户机/服务器的系统),采用Visual Studio 2005作为该聊天系统的开发环境,C#作为开发语言,运行的环境为Windows XP操作系统,后台的数据库使用Microsoft SQL Server 2005。该聊天系统能在局域网实现聊天功能,提供用户
注册、登录、聊天、修改个人信息、查找/添加好友、更换皮肤、听音乐等功能。

Abstract
With the development of computer, Internet has entered our daily life, the most frequently use of Internet is Internet Chatting System. Therefore, it is very valuable and meaningful to study and research Internet Chatting System. Internet Chatting System can help people in chatting with other people far away. You can also have visual talk with other people through Internet Chatting System.So, it can help people to develop friendship with any people who are able to search Internet in the world. The earth looks like smaller than before because you can have relationship with people more convenient.
It is based on the system of C/S, use Visual Studio 2005 as exploit language of the environment. Its running environment is Windows XP operating system. And uses Microsoft SQL Server 2005 as its background database management system. Clients can run this Internet Chatting System under Windows XP environment.This system can do a full management on scientific project and scientific and technology paper, providing necessary functions of everyday management, for example, data input, query with more conditions, statistics, report forms output etc. and easy to use.
