Description: 一个简单的FTP的源码
编译环境：VC6.0.
编译方法：编译前先将本机上的VC98文件夹下的winsock.h搜索到并删除,
然后开始编译，并将windows.h文件中的以下语句删除：
#else
#include<winsock.h>
最后编译就可以通过了。
使用方法：将本工程const.h文件中的相应设置进行更改，就可以用leapftp进行连接了
(目前尚不能支持其他的ftp客户端软件)

Description: 本文对 H.263/H.263+视频编解码系列的基本原理、系统结构和压缩方法等做了简
要分析，并对运动估计方法作了算法上的改进，提出了一种提前预测运动矢量分级搜索
的方法，该算法搜索点少，运算量小，精度也比较高。在此基础上，以H.263/H.263+视
频编解码算法为核心，结合Winsock编程和多线程处理等技术，在局域网内实现了基于
PC机的图像实时传输。另外，结合TI公司的高性能定点处理芯片TMS320C6416的结
构和特点，利用多种优化方法，对H.263/H.263+的编码程序进行代码级的优化，并最终
在TMS320C6416 DSP芯片上实现了对H.263/H.263+视频编码过程的实时处理，获得了
良好的压缩效果和处理效率。

Description: I ve done alot of hard work to bring you an easy way to use winsock in your applications. This code is well commented. Shows how to use SOCKETS, winsock2.h and alot of other stuff. Connect, Listen, Send Data, Get data etc.
I created a class to make it easy to use winsock. It s portable to other code. I created a small application in console mode (for simplicity on my part since i dont know much MFC and i didnt want to create an OpenGL interface) called "WeakStick Chat". This code can be improved apon, so please let me know if you do.

Description: 这个工具采用的是HOOK进程的winsock API，把一些数据记录下来。
2.1 patch静态文件，即运行前挂钩.
2.2 也是修改IAT，跟1.1一样.
2.3 修改目标函数的前几个字节，跳转到新的函数，但不再调用原始函数，无
实际意义，作者只是做演示？
2.4 这种方法(3.2.3 保存原始函数)很COOL，其中的亮点和难点就是“获取任意
地址的指令长度”。
之前我也想用2.4这种办法，但卡在如何“获取任意地址的指令长度”上面了:(
在看到《挂钩Windows API》这篇文章之前，我取了一个比较简单有效的办法：
3.1 把目标函数的DLL COPY一份到内存中，修改原目标函数的前几字节，跳转
到我们的函数，在我们的函数中调用原函数新的COPY。-AppWizard has created this xHook DLL for you.

This file (the project file) contains information at the project level and
is used to build a single project or subproject. Other users can share the
