UDP-communication

说明：  是一个通过网络对软件进行自动更新的系统,可以使用这个程序为你的软件提供远程升级功能(Is a network of software auto-update system, you can use this procedure for you to provide remote software upgrade capability)

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.)

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

快递发送单查询通信，　利用了socket(Courier to send single query communication using a socket)

socket建立连接超时的控制 (Controlling socket when timeout)

简单TCP双向通讯例子，实现客户端服务器端的双向通讯。(Simple the TCP bidirectional communication example, to achieve the client server-side two-way communication.)

说明：  基于CSocket的TCP多人聊天程序 平常自己练习用的！(CSocket of TCP-based chat program over usual practice their own use!)

基于TCP/IP的多人聊天程序(包含服务器和客户端)( Chat the procedure based on the TCP/IP multi- people (to contain server and customer end) )

广播... 可以供初学网络编程的人参考... 完整 并且在winXP Visual C++6.0调试通过(... can Broadcasting Network Programming for the novice to the integrity of reference ... in winXP Visua l C by 6.0 Debugging)

CPing依据ICMP协议实现, 可解析域名和IP, 可设置发包数量,统计丢包率(CPing based on ICMP protocol implementation can resolve domain names and IP, you can set the number of contracting, statistical packet loss rate)
