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

socket 编程基础 里面主要是介绍性文字和少量代码(socket programming which is mainly based introductory text and a small amount of code)

核心实例 POP3上电子邮件的检查,POP3协议，网络编程(POP3 email check)

我的毕业设计，一个简单的集聊天，文件传输于一体的vc源码，可选TCP或UDP传输模式！(My graduation project, a simple set chat, file transfer in one vc source, optional TCP or UDP transfer mode!)

这是VB6.0上MSDN的例子，不过我做了稍微改动，能实现输入任意的IP地址，实现与其通信的目的(This is a VB6.0 example on MSDN, but I make a slight alteration can realize arbitrary input IP address, the realization of the purpose of communication)

关于WSAEventselect模型的使用，这个模型和WSAAsyncselect很相像，但是使用方法还是要注意(About WSAEventselect model used is very similar to the model and WSAAsyncselect, but still have to pay attention to use)

说明：  Source code Image matching source code for image matching

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!)

使C++语言编程，实现双机在联网条件下通过IP地址实现通信。(With C++,we can make two computers commnicate with each other when they are on the Internet.)
