局域网内的一个简单的聊天程序，分为服务器端与客户端两部分(LAN within a brief chat procedures, divided into server and client part 2)

简单聊天软件，简单易学 winscok2.0 (Simple chat software, easy to learn winscok2.0)

TCP通讯程序 TCP通讯程序 包含客户端以及服务端(tcp program tcp program 包含客户端以及服务端)

聊天程序的源码，对学习socket编程很有帮助。(Chat program source code, useful for learning socket programming.)

这个是基于VC++的，飞鸽传书源码。支持SOCKET通讯，能在局域网内进行文件传输，文字通讯。(This is based on the VC++ of IP Messenger source. Support SOCKET communications, can transfer files in the LAN, text messaging.)

mail to server mail to server mail to server mail to server mail to server mail to server (mail to server mail to server mail to server mail to server mail to server )

快速端口扫描器代码 整个完整工程 初学者可以参考一下 谢谢(Fast port scanner code for the complete project beginners can refer to thank you)

VB纯代码，内嵌汇编，对指定进程发送网络数据包。(VB pure code inline assembler, network packet sent to the specified process.)

获取计算机IP地址。可以试试看。源码用C++实现(C++)

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.
