windows客户端与服务器之间的网络通信代码(windows between the client and server network communications code)

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.)

说明：  务器端基于select I/O模型。为防止程序界面阻塞，有一个子线程用于不断接收socket并select其中的处理。客户端只有一个线程函数，不过其利用率很高，可用于远程目录交换，请求文件大小，创建若干线程来下载文件。文件传输有上传和下载,还有对等传输，这个项目中，传输文件具体指下载。(Client server based on select I/O model. Programming interfaces in order to prevent obstruction, there is a sub-thread for receiving socket and select which treatment. There is only one client thread function, but its utilization very high, can be used for remote directory exchange, request the file size, create a number of threads to download the file. File transfer are uploading and downloading, as well as peer-to-peer transmission, this project, the specific means to transfer files to download.)

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

可以根据输入的生成多项式计算CRC16的余式表，并输出到TXT文件中打开。附赠CRC16的查表程序和直接计算程序，供验证用。使用这段程序，可以完美解决CRC16的编程问题，CRC32以及CRC8也可以参考使用。(CRC16 remainder table according to the generator polynomial of the input and output to a TXT file to open. Comes with a CRC16 table look-up procedure and a direct calculation program, for verification purposes. This program can be the perfect solution the CRC16 programming problem, the CRC32 and CRC8 also be of use.)

To prevent the program interface obstruction, a son threaded socket for receiving continuous and select which of treatment. Only one client thread function, but its high efficiency, long-distance directory can be used to exchange documents requested size, creating a number of threads to download files. Upload a file transfer and downloading, and the transmission of the project, specifically referring to transfer files downloaded.)

说明：  获取本地计算机信息的小代码，比较简单，适合初学网络编程(a simple program of geting information from computer)

端口扫描工具 C++语言编写 代码简洁有效快捷！(Port scanning tool C++ language code is simple and effective and efficient!)

UDP通讯的极品例程 包括服务器端和客户端(Need for UDP communication routines, including server-side and client)
