Visual Basic 6.0 网络通信协议分析与应用实现 很不错的随书源码 分享给大家...

一个socket通信客户端-a socket communications client

使用VC++6.0实现的一个网络通信小程序-Use VC++ 6.0 realize a network of small procedures

计算校验和 命令行：check_sum infile 其中check_sum是程序名，infile是数据文件名 输出：数据文件的校验和。 目的是通过数据链路层与介质访问控制层的学习，根据数据链路层的基本原理，针对普遍应用的Ethernet帧，通过构造一个具体的帧，深入理解网络协议的基本概念与网络问题处理的一般方法。-calculated checksum command line : check_sum infile which check_sum procedures, and infile data output file name : data files, the checksum. The purpose of the data link layer and the MAC layer of learning, according to the data link layer to the basic principles of universal application against the Ethernet frame, and by constructing a concrete frames, in-depth understanding of network protocols and the basic concepts of network issues to deal with the general approach.

基于VC实现的串口通信程序,可以用于测试串口的连接,也可供进行源码学习.-NOTE: serial port communication procedure based vc,It can be used to test serialport s connection,and also study source!

GPIO口模式下的网络设备的测试程序，包括命令测试和数据测试-GPIO port mode network equipment testing procedures, including testing and data testing orders

非常好的源代码程序-very good source code procedures

本源文件是tcp的连接程序，可以当服务端或客户端，包括连接、收发数据等功能，在所有过程出错处理都较好。-origin of the document is tcp connections and can be a server or client, including connections, sending and receiving data and other functions, in all processes are better error handling.
