编写程序，实现基于ARP协议获取本局域网内全部活动主机MAC地址与IP地址对应关系列表，要求使用Winpcap，手动封装ARP数据包，并实现ARP响应数据包的接收和解析。(programming, ARP-based LAN access to the activities of all MAC address and IP address correspondence list, require the use of Winpcap, manual Packaging ARP packets, and achieve ARP response data packet reception and analysis.)

移植的一个基于osip，使用vc编译的siproxd服务器软件(port siproxd to win32, compiled using vc)

代码是用来实现使用IP地址控件显示和设置IP地址的vc代码,好，有需要的朋友可以看看(Vc code is used to display and set the IP address using the IP address of the control code, need friends can look at)

求一段音频信号的短时过零率，可用于特征的选取，以及对音频进行分类筛选等场合。(For the sound process)

SOCKET编程规范(SOCKET programming specification)

raw socket编程，探测网络包。 vc++, win2000测试通过。(raw socket programming, detect network packets. vc++, win2000 test passed.)

创建一个新进程范例。这是孙鑫视频中的范例，能帮助初学者了解进程的相关知识，可以看看，虽然比较简单(create a new process in vc++)

Currently, most of people use MS DCOM/COM+, Java Bean/RMI, and Corba to do distributed computing over internet. All of these technologies are provided with some tools and intermediate objects to simplify internet development. However, these technologies have one common and fundamental problem that all of the calls between a client and a server are blocked for a returned result (please correct me if this is wrong). A client stays still, and has to wait for a while after sending a request to a server. If the request is a lengthy action, the client application seems to be dead to a user. In most cases, we could use a worker thread at the client side to do background computation for solving this problem. However, this comes with an expensive price, more coding, data synchronization and mess in coding logic. Additionally, I also doubt that these technologies are able to really move data across internet efficiently.

用来通过HTTP协议下载的程序，支持断点续传和多线程下载(Used to download the program through the HTTP protocol, support HTTP and multi-threaded download)

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.)
