简单的用于查看本机端口的应用程序，通过netstat命令实现(a simple application for local port view)

SYN Flood是当前最盛行的DoS（拒尽服务进攻）与DDoS（散布式拒尽服务进攻）的方法之一，这是一种利用TCP协议缺点，发送大批伪造的TCP连接请求，从而使得被进攻方资源耗尽（CPU满负荷或内存不足）的进攻方法。(SYN Flood is one of the most popular DoS (refuse to do service attack) and DDoS (Distributed refuse to do service attack), which is a Use the TCP protocol shortcomings, sending a large number of forged TCP connection requests, making the offensive resource exhaustion (CPU full load or memory) Offensive....)

如果你开发过Windows NT系统上的网络软件，肯定碰到过让用户选择要求连接的或登陆的计算机或者域名的情况。这种情况下肯定用过外壳API函数，像SHGetSpecialFolderLocation 和 SHBrowseForFolder，并显示标准的资源管理器对话框(If you develop Windows NT system over the network software certainly encountered allows users to connect selecting the landing or the computer or domain name situation. Under these circumstances certainly used shell API function, and as SHGetSpecialFolderLocation SHBrowseForFolder and display standard resource management for dialog)

自动更新。与需要更新文件放在同一目录，生成更新文件；客户端通过HTTP去请求更新文件，进行文件版本比对，选择需更新的文件进行下载。其中使用了NewLife框架代码，具体源码请移步至www.newlifex.com(Automatically updated. And the need to update the files in the same directory, generate update files client requests via HTTP to update files, file version than the right, select the file to be updated to download. Which uses the NewLife framework code, the specific source please venue to www.newlifex.com)

实现TCP通信服务器端和客户端（支持多个客户端）精简版(Implementation of TCP communication server and client (support multiple clients) simplified version)

一般的聊天程序都是使用socket方式通讯的。对于一个聊天程序来说一般是一个服务器用来中转消息，然后是多个客户端通过连接服务器来消息交换。(General chat programs are using the socket mode of communication. For a chat program, it is generally a server used to relay the message, then multiple clients to connect to the server through the exchange of messages.)
