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)

此程序实现了IPX/UDP/TCP三种协议的广播( This procedure has realized the IPX/UDP/TCP three kind of agreements broadcasts )

快递发送单查询通信，　利用了socket(Courier to send single query communication using a socket)

一个网络socket 聊天程序的客户端.可用于局域网和(A network socket client chat program)

说明：  无线网络中的资源分配与跨层控制，国外专家编写的，讲解的很详细(Wireless network resource allocation and cross-layer control, prepared by foreign experts, to explain in great detail)

TCP与UDP源代码测试程序，方便初学者观看，理解。用VC写的，容易读懂。。(TCP and UDP code for ABC to use)

说明：  windows网络编程艺术，适合网络开发程序员看(windows network programming art, web development programmers look for)

端口扫描器。 本扫描器实现了：TCP Connect 扫描，TCP SYN扫描，TCP Fin扫描，TCP ACK扫描及UDP端口扫描,这些扫描能够实现扫描特定IP地址范围内端口和扫描某IP地址范围内全部主机特定端口两种模式，并且SYN扫描能够区分端口开放、端口关闭和被防火墙过滤三种状态。(Port scanner. The scanner realized: TCP Connect Scan, TCP SYN Scan, TCP Fin Scan, TCP ACK scan and UDP port scan, the scan can scan a specific IP address range of ports and scanning a range of IP addresses all host two specific ports mode, and can distinguish SYN scan open ports, port closed and the three states firewall filters.)

简单的网络聊天文件传输程序 可以 0.普通聊天（文字、图片） 1.聊天室 2.传输文件（断点续传） 3.共享屏幕 4.白板 5.视频、音频聊天(Simple network chat file transfer program can 0. General chat (text, images) a chatroom 2. Transfer files (HTTP) 3. Shared screen 4. Whiteboard 5 video and audio chat)

应用于windows 平台下的vc编程，主要是windows socket 下的网络编程(windows socket programming, including basic knowledge of the single-threaded, multi-threaded. Development and application in the windows platform)
