GifCodec
参考网上的资料写的gif编解码。
编码用gdi解析常用图片格式，然后组装成gif
解码吧gif的每一帧转换成dib
gif文件格式网上有很多介绍
gif用的变长lzw压缩算法：
没弄懂原理，只知道过程。压缩取一个字符作为后缀，看看字符串是否存在。存在，用对应的编码作为前缀继续取；不存在把字符串添加到字典，前缀添加到输出流，后缀作为前缀继续取。解压取一个编码看看字典中是否存在。存在用对应的字符串的第一个字符作为后缀，看看当前字符串是否存在，不存在添加到字典中，后缀作为前缀，前缀对应的字符串添加到输出流，继续取；编码不存在，前缀对应的字符串的第一个字符作为后缀（这时当前字符串肯定不存在，字典中下一个可用编码肯定等于刚取出的编码），字符串添加到字典中，编码作为前缀，前缀对应的字符串添加到输出流，继续取。
编码流转换成字节流是按位从低到高的，window是小端模式（低字节在低地址），字节内低位在右边。
24位dib转换成8位dib时使用的八叉树算法
图片拉伸时参考的网上的双线性插值算法。
字典满了位数加一，位数是12时不加(Online reference materials written gif codec.
Encoded using gdi resolve common image formats, and then assembled into a gif
Each frame decode it into a gif dib
There are many online gif file format introduced
gif lzw with variable length compression algorithm:
Did not understand the principle, only know the process. Compression takes a character as a suffix, and see if there is a string. Exist as a prefix to continue to take with the corresponding encoding there is no string to add to the dictionary, a prefix added to the output stream, the suffix as a prefix to continue to take. Take a look at extracting coding dictionary exists. Exist with the corresponding first character string as a suffix to see the current string exists, there is no add to the dictionary, the suffix as a prefix, the corresponding string to the output stream, continue to take coding does not exist, prefix corresponding first character string as a suffix (when the current string certainly does not exis)

WSAEventSelect_Test_IO
关于WSAEventselect模型的使用，这个模型和WSAAsyncselect很相像，但是使用方法还是要注意(About WSAEventselect model used is very similar to the model and WSAAsyncselect, but still have to pay attention to use)

穿目前所有还原下载者 C 源码
说明： [C/C++] 穿目前所有还原的下载者 C++源码
下载者包括四个工程：
CDown：生成器
userinit：真正的下载者
Dat：驱动和下载者的安装程序
pass：驱动程序
原理：驱动程序可以穿透还原卡，并且可以修改系统文件，这里是通过修改系统文件userinit.exe来实现的。userinit.exe的功能很简单，就是启动explorer.exe。这里就是通过替换uerinit.exe，伪造一个userinit.exe。这个伪造的程序可以实现uerinit.exe的原始功能，并可以实现自定义的功能，比如下载执行，发送数据。
驱动的功能就是替换指定的系统文件。
将userinit Dat pass 编译出来的文件放到cdown的res里，再生成出生成器就可以使用它生成下载者，也就是这个穿还原的程序([C/C++] wear all current restore downloader C++ source code
The download includes four projects:
CDown: generator
Userinit: a true Downloader
Dat: driver and downloader installer
Pass: Driver
Principle: driver can penetrate the restore card, and you can modify the system file, here is through the modification of system file userinit.exe to achieve. The function of userinit.exe is simple, that is, to start explorer.exe. This is where you forge a userinit.exe by replacing uerinit.exe. This fake program can realize the original function of uerinit.exe, and can implement custom functions, such as downloading, executing and sending data.
The driver's function is to replace the specified system files.
The userinit Dat pass compiled files into the Cdown res, regeneration into the generator, you can use it to generate the download, that is, the process of wearing a restore)
