基于winsock网络编程技术实现客户端图片传送到服务器端

在WINDOWS下进行网络服务端程序开发，毫无疑问，Winsock 完成端口模型是最高效的。Winsock的完成端口模型借助Widnows的重叠IO和完成端口来实现，完成端口模型懂了之后是比较简单的，但是要想掌握Winsock完成端口模型，需要对WINDOWS下的线程、线程同步，Winsock API以及WINDOWS IO机制有一定的了解。如果不了解，推荐几本书：《Inside Windows 2000，《WINDOWS核心编程》，《WIN32多线程程序设计》、《WINDOWS网络编程技术》。在去年，我在C语言下用完成端口模型写了一个WEBSERVER，前些天，我决定用C++重写这个WEBSERVER，给这个WEBSERVER增加了一些功能，并改进完成端口操作方法，比如采用AcceptEx来代替accept和使用LOOKASIDE LIST来管理内存，使得WEBSERVER的性能有了比较大的提高。 -under the Windows network server program development, no doubt, Winsock completed port model is the most efficient. Winsock port model with complete preview of overlap and complete port IO to achieve complete port after the model to understand is a relatively simple, but want to know the complete Winsock port model, the need for the Windows threads, thread synchronization, Winsock API and Windows IO mechanism of a certain understanding. If we do not understand, recommended several books : "Inside Windows 2000," Windows core programming "," WIN32 multithreaded program

rip协议，描述通信双方如何用rip协议进行通信。-rip the agreement, describing how the two sides rip communication protocol to communicate.

首先，客户端的日志服务器，网络地址转换分布为本届会议的一个端口60000 ，那么伺服器收到了用户端的地址是202.187.45.3:60000 ，这是外部的客户网络地址。同样，客户乙登入伺服器， B至吨的NAT-First of all, Client A log server, NAT A distribution for the Session of a port 60000, then the Server S received the address of Client A is 202.187.45.3:60000, which is outside of the Client A network address. Likewise, Client B Login Server S, NAT B to the distribution of the Session of the port is 40000, then the Server S received B s address is 187.34.1.56:40000. At this time, Client A and Client B and Server S can be a communication. If Client A at this time would like to direct

一个不错的投票系统，可多选，单选，规定投票次数，无限添加投票项目-a good voting system, may choose, radio, voting frequency, add unlimited voting project

在Windows环境下，基于VC开发UDP协议的发送和接收实例，这个程序不仅可以学习和了解网络中通信协议的工作，而且对于学习者来说，是一个不错的调试工具。

本程序用MFC基于对话框实现了windows下的socket通信，分别实现了TCP通信、UDP通信以及UDP组播通信。可以发送字符串也能发送16进制的数据。socket使用了非阻塞模式，并且是事件触发的。
