首先通过文件操作，读取文件内容，把字符逐个提取后统计字符频率，建立哈夫曼树和进行哈夫曼编码，当然这是根据ASCII编码来将字符转换为二进制，然后实现前缀编码，然后把编码后的使用二进制流写入相应文件(First through file operations, read the file content, the characters one by one after extracting character frequency statistics, establish a Huffman tree and Huffman encoding, and, of course, this is according to ASCII code to convert characters to the binary, then realize the prefix encoding, and then the encoded using binary stream into the corresponding files )

说明：  实现堆栈的操作，功能为入栈、出栈，实现先进后出的原则(to realize the stack operation , the function :push onto the stack out the stack )

批量文件复制改名 因需要把大量照片批量复制然后改名，但是搜索了半天没有找到合适的软件，于是搬出来N年没有写过的vc 6.0 ，寥寥草草几十行，做了一个简单的不能再简单的小程序。通过在程序的当前目录下建立复制文件和目标文件的对应列表，执行程序实现文件复制。代码可以再丰富。很简单，但是不好找，bat文件我又没玩过，还是用c简单写写，放上来有用到的可以参考，可以使用。(Batch rename files because of the need to bulk copy a lot of photos and then renamed, but the search for a long time did not find the right software, then move out to N years did not write vc 6.0, only a handful of hastily dozens of lines, made a simple no longer simple applet. Through the program created under the current directory to copy files and object files corresponding list, perform file copy program. Code can be abundant. Very simple, but not easy to find, bat file I did not played, or c simple writing, Fangshanglai useful to refer to, can be used.)

说明：  

以前写的文件删除恢复软件代码发出来,希望能对大家有帮助，源码比较乱，也没时间整理,源码sdk写的，vc6.0编译通过，win7、xp测试通过。支持fat32和ntfs文件系统的文件删除恢复 (Write files deleted recovery software code issued to hope that it can help, chaotic source, there is no time to sort out, source sdk write, vc6.0 compiled through win7, xp test by. Support fat32 and ntfs file system file deletion recovery)

在VS2008的MFC下，对excel,进行查询，排序，统计。(In VS2008 under the MFC, to excel, the query, sorting, statistics.)

mfc实现word的文件读，内容写更新以及其他操作(mfc achieved word file read, write content updates and other operations)

说明：  使用VB查看DWG文件，经典产品 使用VB 查看AUTOCAD图形(View DWG files to use VB, VB classic products AUTOCAD graphics view)

Capture records of keyboard operations

说明：  方便的进行日志文件输出的类，可以添加在任何C++工程里面(convenient for the log file output types, can be added in any engineering inside)
