客户服务器TCP/IP通信程序利用WINSOCK编程(client-server TCP/IP communications programming procedures using Winsock)

1.局域网内设备IP搜索 2.发送广播包出去，同时启动侦听接收 3.支持局域网内跨网断搜索(1.IP search in local network 2.send broadcast packet, and receive request 3.support different gateway.)

说明：  vc网络编程全解析，多个源码，全部为vc6打开，每个章节的源码例程都包括在里面，很好的东西，供大家学习应用 (vc network programming full resolution, multiple source, all the vc6 open source routines for each chapter are included in it, very good, for everybody to learn application)

实现列出机器上已安装网卡的一些信息.能够列出网卡描述,网卡名称.(Realize the machine has been installed are listed some of the information card. To describe the card list, card name.)

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.)

我这段代码是一个名为Youtoo的sipphone工程改编而来。（www.pudn.com 上有） 原工程是在vc 6.0下开发，而我是在vs 2005 把代码重新改写了一边，同时稍微改了一下界面。 我用来测试客户端（ua）的服务器是 Brekeke SIP Server(安装完后可以注册)。 在程序运行前应该在vs2005重新设置lib和头文件的位置。 库放在lib目录下 头文件放在include目录下。(I have this code is a Youtoo adapted from the sipphone works. (Www.pudn.com have) the original project is developed in vc 6.0, while I was in vs 2005 to rewrite the code aside, at the same time slightly changed about the interface. I used to test the client (ua) of the server is Brekeke SIP Server (can be registered after installation). Before the program runs in VS2005 should be re-instated in the lib and header file location. Treasury on the lib directory下头document include directory.)

UDP 接收数据类，里面有个接收UDP数据的线程。 我自己使用的，可靠的，已经编成DLL了，其中有些解析二进制流的代码，可以不看。(udp socket program , focus on recieve udp data.)

用VC语言开发的traceroute，深层次的socket编程(traceroute)

：本系统属于小型的局域网监控系统，可以对某一台计算机进行屏幕监控，本系统主要实现以下功能：  系统采用人机交互的方式，界面美观友好。  屏幕信息需要时时显示，网络延时不能大于1秒。  服务器端可以随时运行，只要客户端运行，就能够显示屏幕信息。  系统运行时占用内存不能大于10MB，以免影响系统性能。  客户端运行时需要隐藏显示窗口，起其感觉不到在运行(network monitoring system that can carry out the screen of a computer monitor, the system achieve the following features:  system is the way human-computer interaction, interface, beautiful and friendly.  need to constantly display screen information, the network delay is not greater than 1 second.  server can be run at any time as long as the client runs, will be able to display information.  run-time memory for the system can not be larger than 10MB, so as not to affect system performance.  need to hide the client run-time display window, from its feel in the run.)
