判断IP是否有效

较好的解释了网络聊天室的构建过程-better explanation of the Internet chat room Construction

加强版的netstat。有嗅探功能（需更改源码手动打开），发现新连接时还有任务栏弹出窗口提示功能。需要sdk。-strengthened version of netstat. A sniffer function (subject to change manually open source), the discovery of new connections have taskbar pop-up reminder feature. Need sdk.

通过设置发送并接收消息：可以设置端口，波特率，奇偶校验等参数.用TCP/IP实现客户/服务器模式.-send and receive news : you can set ports, baud rate, parity and other parameters. Using TCP/IP client/server model.

读写.Excel文件，还可以创建.Excel。Visual C＋＋6.0开发。-Read and write. Excel documents, can also create. Excel. Visual C 6.0 development.

在Internet上的聊天室程序一般都是以服务器提供服务端连接响应，使用者通过客户端程序登录到服务器，就可以与登录在同一服务器上的用户交谈，这是一个面向连接的通信过程。因此，程序要在TCP/IP环境下，实现服务器端和客户端两部分程序。-In Internet chat rooms on the procedure is generally based on the server side connection in response to the provision of services, the user through the client program to log on to the server, you can log in the same server with the user to chat, this is a connection-oriented communication process. Therefore, procedures to TCP/IP environment, the realization of server-side and client procedures in two parts.

客户机/服务器模型是为了解决通信中的聚合问题。如果不采用客户机/服务器模型很难实现正常的通信，只有在一方作为服务器采用被动方式，始终等待对方与其通信；另一方作为客户机采用主动通信的方式，主动发起通信过程，才能最终完成通信。-client/server model is to solve the communication problems polymerization. If we do not use the client/server model is very difficult to achieve normal communications, as one of only a passive server, which has been waiting for communication with the other side; The other client as an active communication, initiate the communication process can be finalized communications.
