程序互斥代码，防止一个程序多次启动，很有效，加在工程文件中效果很好。(Program mutex code, to prevent a program started several times, very effective, plus good results in the project file.)

针对Windows下的文件夹，可以创建、删除、复复制、查找、枚举等操作(For Windows folder, you can opetate it as create, delete, multiple copy, find, enumeration and so on)

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：  第一次上传东西里面是一个udf文件边界条件设置(From inside the first thing is to set the boundary conditions of a udf file)

一个vc++的Excel操作类，可以在当前目录生成Excel文件，也可以读取外部Excel文件，编译运行如上示，这是个很实用的类库。(A vc++ to Excel operation class, you can generate Excel files in the current directory, you can also read an external Excel file, compile and run as above said, this is a very useful library.)

C++中对EXCEL的操作，包含绝大部分EXCEL的功能，如单元格格式操作等。(There has been the C++ project BasicExcel for quite some years now. It is very useful to read and write Excel sheets in .xls format. However, it contains only very basic functionality. There are missing features like text formatting using fonts, and display formats and formulas are not yet supported. This article covers this additional functionality. The new, derived project ExcelFormat is based on the old BasicExcel code, and just adds what I was missing for my own needs. If you want to see where I am using the new library, you can look at the Export functions of Service Manager and Uninstall Manager.)

这个类似文件搜索的非WINDOWS编程.如果对于你们有帮助也是好事(The non-WINDOWS similar documents search program if help is good for you)
