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。 (side is based on the Treasury select I/O model. 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.)

我这段代码是一个名为Youtoo的sipphone工程改编而来。（www.pudn.com 上有） 原工程是在vc 6.0下开发，而我是在vs 2005 把代码重新改写了一边，同时稍微改了一下界面。 我用来测试客户端（ua）的服务器是 Brekeke SIP Server(安装完后可以注册)。 在程序运行前应该在vs2005重新设置lib和头文件的位置。 库放在lib目录下 头文件放在include目录下。(I have this code is a Youtoo adapted from the sipphone works. (Www.pudn.com have) the original project is developed in vc 6.0, while I was in vs 2005 to rewrite the code aside, at the same time slightly changed about the interface. I used to test the client (ua) of the server is Brekeke SIP Server (can be registered after installation). Before the program runs in VS2005 should be re-instated in the lib and header file location. Treasury on the lib directory下头document include directory.)

本程序以动态的方式给对话框加载背景图,给人耳目一新的感觉()

一个关于局域网文件传输的源代码，很适合课程设计，客户端和服务器端(on a LAN file transfer the source code is well-suited to the curriculum design, the client and server)

用vc6.0实现的强大有界面的sockets通讯程序，可使server端与client端即时通信，需先运行server端。(Vc6.0 achieved using a powerful interface sockets are the communication process, will enable the server-side and client-side real-time communications, the need to run server-side.)

说明：  为解决实际测控系统中在控制中心的上位机和控制功能设备的下位机之间传送命令和文件的问题,在讨论VC++6.0中MSComm控件的基础上,通过制定通信协议、给命令和文件加入标识构成包进行传送,从而正确地区分了命令和文件.实验表明,基于该通信协议,可以成功地传送命令和多类型文件. (To address the actual measurement and control system in the Control Center PC and control functions of equipment under the digital transmission between orders and documents, in discussing the VC++ 6.0 in MSComm control on the basis of the communication protocol through the development to the orders and adding logo files constitute a packet transmitted, thereby correct distinction between the orders and documents. The experimental results show that based on the communication protocol, you can successfully send a command and multi-type documents.)

一个网络聊天的小工具，自己加了时间的功能，客户端(A network of small chat tools, increases the function of time, the client)

基于VC++的局域网聊天室，能够实现多人房间聊天。(LAN chat room based on VC++ can realize multi-room chat.)

自己写的一个http 客户端源代码，供大家学习参考。(http client source code for all to learn)
