基于ping的源代码，实现原始套接字编程(Ping-based source code, to achieve the raw socket programming)

再者个网络时代，伴随着有线网络的广泛应用，以快捷高效，组网灵活为优势的无线网络技术也在飞速发展。本文将简单介绍无线局域网相关技术及其相对有线局域网的优势，并具体介绍如何通过VC6.0设计和实现能同时运行在有线局域网和无线局域网上的简单通信软件。(network era, along with cable network widely used to provide a quick and efficient. flexible network edge wireless network technology is also expanding rapidly. This article briefly introduces wireless LAN technology and its relative advantages of the wired LAN. and the specific details of how VC6.0 design and implementation can also run on the LAN cable and wireless LAN simple communications software.)

WINPCAP 抓包工具，可以用来抓包等功能，十分简单的代码，可以直接使用(WINPCAP tools)

用vc实现的sniffer，没有使用winsock与winpcap。十分具有学习价值！(Vc realize with the sniffer, did not use winsock with winpcap. Very much with learning the value of!)

孙鑫VC++教学课程lesson14：网络的相关知识，网络程序的编写，Socket是连接应用程序与网络驱动程序的桥梁，Socket在应用程序中创建，通过bind与驱动程序建立关系。此后，应用程序送给Socket的数据，由Socket交给驱动程序向网络上发送出去。计算机从网络上收到与该Socket绑定的IP+Port相关的数据后，由驱动程序交给Socket，应用程序便可从该Socket中提取接收到的数据。网络应用程序就是这样通过socket进行数据的发送与接收的。TCP与UDP的工作原理与编写过程，如何在程序中链接库文件。一个字符界面的聊天程序。(Sun Xin VC++ tutorial lesson14: the knowledge of the network, network program, Socket is connected applications and network drivers bridges, Socket application to create, build relationships bind driver. Thereafter, the data of the application to give socket, by the Socket handed driver and sent out on the network. After binding with the Socket IP+Port related data is received by the computer from the network, by the driver to the socket, the application can extract the data received from the Socket. Network application is sending and receiving data through the socket. TCP and UDP works and the writing process, how to link library files in the program. A character interface chat program.)

StressMark测试软件是一个使用Visual C++编写的，开放源代码的测试工具，可以完成服务程序及重要算法的功能和性能测试，其最主要的功能是模拟多线程或多客户端的自动化压力测试。(StressMark test software is a Visual C prepared in the open-source testing tool, service procedures to be completed and important algorithm functional and performance tests, its main function is simulated multi-threaded or multi-client automation pressure tests.)

此程序实现了IPX/UDP/TCP三种协议的广播( This procedure has realized the IPX/UDP/TCP three kind of agreements broadcasts )
