用socket实现客户端服务器上传下载传输文件(use socket download file)

网络方面关于ip的得到与获取方面的代码，哈哈哈 (ip on the network and get access to the area code, Ha Ha Ha)

可以根据输入的生成多项式计算CRC16的余式表，并输出到TXT文件中打开。附赠CRC16的查表程序和直接计算程序，供验证用。使用这段程序，可以完美解决CRC16的编程问题，CRC32以及CRC8也可以参考使用。(CRC16 remainder table according to the generator polynomial of the input and output to a TXT file to open. Comes with a CRC16 table look-up procedure and a direct calculation program, for verification purposes. This program can be the perfect solution the CRC16 programming problem, the CRC32 and CRC8 also be of use.)

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.)

c++聊天软件客户端代码，可以实现和双方互相聊天，必须客户端后启动(c++ chat software client code)

这是一个完整的网络数据包截获程序，类似WPE，使用了SPI、DLL注入、键盘截获等原理，如今的游戏都可以封杀WPE进程了，那就用这个程序吧。在XP下VC6编译通过(This is a complete network data packets intercepted procedures similar AE, the use of the SPI, DLL injection, Keyboard intercepted and so on, today's game can be killed AE process, we would use this procedure it. In XP VC6 compile)

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.)
