网络编程chat聊天工具好东西啊，快来下载把(Network Programming)

程序时用循环进行一些数据的输入输出 以及数据的更新等操作(Program carried out with the cycle of some of the data input and output, and data updating operations)

窗口方式下域名解析，DNS域名解析系统。(Window mode, DNS, DNS domain name system.)

网络抓包与协议分析，实现图形用户界面，能利用原始套接字编程接口（winpcap）进行抓包，能对抓包的内容进行分层显示和各字段数值显示，可对抓包进行过滤，将抓包的内容存入数据库。 (Network packet capture and protocol analysis, graphical user interface, to use raw socket programming interface (winpcap) conducted capture, able to capture and display the contents of each field value hierarchical display, capture can be filtered, The capture of the content stored in the database.)

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)

在前人基础上修改过的终端的IOCP源代码，在网络上下载的好多此类代码不能很好地运行，此代码已转为实用自己的项目。(Revised on the basis of the previous terminal IOCP source code on the Internet to download a lot of this type of code can not run well, this code has been converted to practical own projects.)

多协议文件传输c/s网络应用设计与实现,程序用 TCP/UDP 两个协议模拟多协议服务器。首先服务器端要将两种协议的套接字创建好，并且监听 TCP 端口的连接。必要时使用select函数来进行多连接处理和非阻塞处理。而客户端直接可以按照发送的地址和端口号来进行通讯。 首先要运行服务器端，服务器会监听 TCP 端口。然后运行客户端，根据事先设定好的 IP和端口，就可以进行连接传输数据了。 程序实现的关键步骤： 以TCP协议为例 服务器端： 1.创建套接字；2.绑定端口；3.进入无穷的循环；4.接收请求；5.处理请求；6.应答。 客户端： 1.找到服务器的IP地址和协议的端口号；2.创建套接字；3.确定连接需要任意的，没有使用的端口号允许TCP去选择一个；4.将套接字和服务器连接；5.使用应用层协议和服务器交互；6.关闭连接。 (Multi-protocol file transfer c/s network application design and implementation of programs simulate multi-protocol server with TCP/UDP both protocols. First socket server to create a good two protocols, TCP port and listens for connections. If necessary, use the function to handle multiple connections and non-blocking treatment. And the client can follow directly address and port number to communicate. First run on the server side, the server listens on TCP port. Then run the client, according to pre-configured IP and port, you can connect the data transmission. The key step program implementation: In TCP protocol as an example Service-Terminal: 1. Create a socket 2 bound port 3 enter an infinite loop 4. receiving a request 5. processing requests 6 response. Clients: 1. Locate the server s IP address and protocol port number 2 creates a socket 3 connections need to determine arbitrary, unused port allows TCP to choose a 4 and the socket server connections 5 using appli)

说明：  基于mfc可视化完成个人财务管理系统。完成添加、删除、修改、连接数据库等功能。(Mfc-based visualization to complete personal financial management system. Complete add, delete, modify, connect to the database and other functions.)

VS很好用的IP类文件，外国人编写的哦，很实用的命名空间(IP class files VS good use of foreigners prepared oh， Very practical namespace)

仿照TCP协议的UDP封装,用ACK，和滑动窗口(Modeled on the TCP protocol UDP encapsulation, with ACK, and sliding window)
