netchatbar

这是一个用vc++编写的，用以截获以太网数据的代码。(This is a used vc++ Prepared for Ethernet data intercepted code.)

说明：  vb做的局域网监控系统，同学的毕业设计，研究winsock很有用(vb to do the LAN monitoring system, students graduating from design, research useful winsock)

学习网络编程的初学者必看的.(Learning Network Programming Watchable the beginners.)

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)

说明：  获取本地计算机信息的小代码，比较简单，适合初学网络编程(a simple program of geting information from computer)

VB开发的IP测试程序，这是在我工作中写的调试程序，在配置文件中只需要写上相应的IP，程序就会循环测试IP地址是否在线，不在线的话就会报警提醒(VB development of IP test program, which is written in my work debugger, just write in the configuration file on the corresponding IP, the program will loop test IP address is online, not online, then it will alarm to remind)

UDP 接收数据类，里面有个接收UDP数据的线程。 我自己使用的，可靠的，已经编成DLL了，其中有些解析二进制流的代码，可以不看。(udp socket program , focus on recieve udp data.)

用Visual C++编写的UDP客户端程序。(Using Visual C++ Prepared UDP client program.)

一个可以观察本机上网过程的小程序,使用了SHDocVw组件和MSHTML组件,()

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.
