一个网络状态检测的源码

通过替换wsock32.dll 来监测winsock调用。本文是在已发表的另一文章略加修改而成，先感谢前任怍者。-Replacing wsock32.dll monitoring protocols of call. This article was published in another article slightly modified from first to thank the former were ashamed.

简单的多线程聊天工具，用MFC编程实现，对初学网络编程的人是个很不错的开始。-Simple multi-threaded chat tool, using MFC Programming for beginner of network programming is a very good start.

程序说明: 1.程序采用网上介绍的方法实现最基本的P2P方式通讯.模拟实现即时消息互发. 2.P2P通讯说明: 1).网关类型是在理想状态下.即非对称型NAT. 2).同在一个内网的两个CLIENT端通讯时,如果网关NAT不支持环回,将会失败. 文件目录说明: tQServer:程序服务端,请将其放在公网上运行. tQClient:程序客户端,可以在不同的内网中运行登录连接到服务端. Common:公共协议文件夹 本程序只是实现简单的P2P互发消息.完成的比较粗糙,更多功能欢迎朋友们更新完善-procedures : 1. Online procedures introduced by the most basic method of peer-to-peer communication. Simulation made instant messaging each other. 2.P2P communications Note : 1). Gateway is the ideal type of state. That is non-symmetric NAT. 2). In the same period net CLIENT-2 communications, if not support NAT Gateway Circular, will fail. directory : tQServer :-service procedures, I would be grateful if the public on its Internet. tQClient : clients, in different operations within the network login to connect to the server. Common : Public the agreement folder procedure is a simple peer-to-peer updates. completion of the rougher, more functional friends welcome update perfect

用VC编写的socket小程序，有客户端和服务端，两者3次握手建立连接，用到了最基本的socket，bind，listen，send，receive，函数，非常适合初学者，我就是用这个例子学习的socket编程，很经典的例子有，还有小界面-Socket using a small program written in VC, there are client and server, the two three-way handshake to establish a connection, use the most basic socket, bind, listen, send, receive, function, very suitable for beginners, but I just use this example to learn socket programming, it is the classic case in point, there is a small interface
