Winsock

windows网络编程，分为2部分-windows network programming, divides into 2 parts

icmp的部分源代码-icmp partial sources code

串口通信-Serial Communication

一个关于串口通信编程的小程序，使用visual c++编写。-Serial communication programming on small procedures, the use of visual c++ Prepared.

Windows下VC编程，使用Winsocket进行网络通信-Windows programming, the use of network communications Winsocket

P2P dll c++ ,  static emReturnType SetAppType(emAppType AppType);//设置程序类型，服务器emAppType_Server或者客户端emAppType_Client  static emReturnType SetClientCallback(IMsgCallback *pMsgCallback);//设置回调类，回调类继承IMsgCallback接口  static emReturnType Startup();//开启网络  static emReturnType Cleanup();//关闭网络  //Server  以下函数是服务器调用  static emReturnType BeginService(unsigned short nPort);//如果是服务器，调用该函数开启服务，nPort：端口号  static emReturnType EndService();//服务器退出的时候，调用该函数关闭服务  //Client  以下函数是客户端调用  static emReturnType Logon(LOGONINFO* pLogonInfo);//函数登录服务器。pLogonInfo：登录信息，详细见P2PHeaderDef.h->LOGONINFO  static emReturnType Logout();//登出服务器  static emReturnType ConnectAnchor(CLIENTINFO* pClientInfo);//连接主播，该函数是用户调用  static emReturnType SendP2PMSG(CLIENTINFO* pClientInfo, char* pszMsg, int nMsgLen);//发送P2P消息，pClientInfo，要发送的客户信息，如果是用户，则pClientI

该代码实现机对机聊天，抓取对方屏幕，传送文件，可实现TCP/UDP切换-the realization of machine code for the aircraft, chatting with each other screen crawls, and transmission of documents, TCP/UDP handoff

网络续传下载开发源码，类似于网络蚂蚁，网络快车等续传下在软件-network download open source, similar to ants network, Network Express and other software under Resuming

微软ping命令的源代码，代码虽小 但是值得看-ping orders of the Microsoft source code, code is small but worth observing. .

各种套接字接口函数都有其使用的上下文环境和参数规定。上下文环境由程序模式和程序流程决定；参数则有正确和错误之分。因此在根据错误提示信息解决错误时，应注意到这两种情况。-various socket interface function has its use in the context of environmental requirements and parameters. Environmental context by the procedures in decision processes and procedures; Parameters are right and wrong points. In accordance with the wrong message at the wrong solution, it should be noted that both cases.
