此代码通过 NetApi32.dll 中提供的API来实现 Windows 系统中网卡MAC地址的获取-This code Netapi32.dll provided through the API to achieve the Windows System network card MAC address access

下面就给出一个简单的示例,该示例可以捕获到所有经过本地网卡的数据包,并可从中分析出协议、IP源地址、IP目标地址、TCP源端口号、TCP目标端口号以及数据包长度等信息。-Now, given a simple example, the sample can catch all through local LAN data packets can be analyzed from the agreement, IP source address, IP destination address, source port TCP, the TCP port number and the objective data packet length, and other information.

一个系统自动升级程序，可远程自动更新系统。-Automatic escalation procedures, automatically update the system remotely.

此代码可获得本机的mac地址-This code will be the machine mac address

在WINDOWS下进行网络服务端程序开发，毫无疑问，Winsock 完成端口模型是最高效的。Winsock的完成端口模型借助Widnows的重叠IO和完成端口来实现，完成端口模型懂了之后是比较简单的，但是要想掌握Winsock完成端口模型，需要对WINDOWS下的线程、线程同步，Winsock API以及WINDOWS IO机制有一定的了解。如果不了解，推荐几本书：《Inside Windows 2000，《WINDOWS核心编程》，《WIN32多线程程序设计》、《WINDOWS网络编程技术》。在去年，我在C语言下用完成端口模型写了一个WEBSERVER，前些天，我决定用C++重写这个WEBSERVER，给这个WEBSERVER增加了一些功能，并改进完成端口操作方法，比如采用AcceptEx来代替accept和使用LOOKASIDE LIST来管理内存，使得WEBSERVER的性能有了比较大的提高。 -under the Windows network server program development, no doubt, Winsock completed port model is the most efficient. Winsock port model with complete preview of overlap and complete port IO to achieve complete port after the model to understand is a relatively simple, but want to know the complete Winsock port model, the need for the Windows threads, thread synchronization, Winsock API and Windows IO mechanism of a certain understanding. If we do not understand, recommended several books : "Inside Windows 2000," Windows core programming "," WIN32 multithreaded program
