UDPinstance

程序利用多线程技术和socket技术实现网上聊天程序。服务器程序和客户端程序在同一程序里。(This program realizes the chatting fuction using the multithread technique and socket programming.)

利用wincap直接与网卡通讯发送数据，千兆网卡效率达到100 ，全速！！！完全自定义数据包协议传输，数据每秒钟100M字节有木有！(wincap high speed data 100 MBytes/s=1000Mbits/s)

vb局域网对讲机，实现两台机器之间的通信(vb LAN radio to achieve communication between two machines)

很好的RTSP实现，分享给大家使用，已经建有VC工程(Good RTSP implementation, we used to share)

局域网监控系统客户端程序，可以与服务器端的程序一起形成一个局域网监控系统。(juyuwang jiankong kehuduan)

Resource name HTTP and multi-threaded download

说明：  DNS解析系统，通过发送DNS协议包到DNS服务器来获取DNS(DNS analysis system, the agreement by sending a DNS packet to the DNS server to obtain the DNS)

说明：  是一个通过网络对软件进行自动更新的系统,可以使用这个程序为你的软件提供远程升级功能(Is a network of software auto-update system, you can use this procedure for you to provide remote software upgrade capability)

异步套接字编写的网络聊天室程序，根据孙鑫VC++深入详解的例子改写，使用Visual studio 2008 SP1在Unicode编码环境下编写，可以收发中文字符。(Asynchronous socket program written in Internet chat rooms, according to Sun Xin VC++ depth Detailed examples rewritten using Visual studio 2008 SP1 environment written in Unicode encoding, you can send and receive Chinese characters.)

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.)
