FindStudent
课堂随机点名系统。MFC实现。要求能完全实现我们的点名程序已有的功能。即事先从教务处网站上下载某班的学生名单并存盘备用。你的程序能够以某种方式有选择性的加载某个班的存盘文件并把相应的学生信息读入内存，然后以随机的方式来查找某个学生的信息并把它显示出来以实现点名。(Classroom randomly named system. MFC implementation. Requirements to fully realize our program has been named function. That is, from the Office of Academic Affairs Web site in advance of a class of students download and save the standby list. Your program in some way be able to selectively load a class file and save the students put the corresponding information read into memory, then a random way to search a student' s information and put its name displayed in order to achieve .)

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)
