client2

利用VC++6.0来实现一个类似QQ的聊天程序。本程序只实现添加好友，文字聊天，文件传输和语音聊天4大功能。(VC 6.0 to achieve a similar QQ chat program. This procedure will only add to achieve good friend, text chat, file transfer, and voice chat four major functions.)

用pop3实现邮件的接收功能，图形化界面，基于MFC(please read Chinese comments,thank you)

用vc6.0实现的强大有界面的sockets通讯程序，可使server端与client端即时通信，需先运行server端。(Vc6.0 achieved using a powerful interface sockets are the communication process, will enable the server-side and client-side real-time communications, the need to run server-side.)

说明：  Desktop drawing program, for beginners to understand the vc code is a good example, performance fun and easy to learn

aodv源代码，RREP路由回复，RREQ路由请求，RRER路由错误的编写，以及aodv中没有字段中每个参数的描述，以及函数的实现，数据发送的处理和数据接收的处理(aodv，RREP，RRER protocol ,RREQ)

raw socket编程，探测网络包。 vc++, win2000测试通过。(raw socket programming, detect network packets. vc++, win2000 test passed.)

说明：  在Internet上的聊天室程序一般都是以服务器提供服务端连接响应，使用者通过客户端程序登录到服务器，就可以与登录在同一服务器上的用户交谈，这是一个面向连接的通信过程。因此，程序要在TCP/IP环境下，实现服务器端和客户端两部分程序。(In Internet chat rooms on the procedure is generally based on the server side connection in response to the provision of services, the user through the client program to log on to the server, you can log in the same server with the user to chat, this is a connection-oriented communication process. Therefore, procedures to TCP/IP environment, the realization of server-side and client procedures in two parts.)

多线程断点续传类，以及界面。 项目中： _Nv_Http_Download.h _Nv_Http_Download.cpp 就是多线程断点续传类。(Multithreaded HTTP class, as well as the interface. Project: _Nv_Http_Download.h _Nv_Http_Download.cpp is multi-threaded HTTP class.)

应用于windows 平台下的vc编程，主要是windows socket 下的网络编程(windows socket programming, including basic knowledge of the single-threaded, multi-threaded. Development and application in the windows platform)
