说明：  

用于文件的搜索,主要是文件目录下搜索文件名(for file searching,the main of function is that searching the name of files)

可在用户指定的文件夹下，搜索带有某个字符串的文件名称，可指定文件后缀名，可选择区分大小写，可遍历子文件夹。对于搜索到的文件，可批量更改名称，将搜索到的字符串替换为用户指定的字符串，可选择替换，也可选择备份源文件。文件搜索和替换采用多线程实现。(Can be user-specified folder, the search string with a file name suffix can specify the file name, choose case-sensitive, can traverse sub-folders. For the search to the file, you can batch change the name to search for the string replaced with the string specified by the user may choose to replace, can also choose to back up the source file. File search and replace multi-thread implementation.)

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 )

一个打包工具，从电脑的任意盘选择一些file，将内容写入一个自定义的file中并存入自定义的地方(A packaged tool, select some file any disk from the computer to write the contents of a custom file and stored in a custom place)

说明：  能够对dxf文件进行读取,而且是源代码哦(can read the .dxf file)

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.)

VC++逐行读取Txt文本文件，只是一个读写方式的不同，总之最终的目标是读取整个文件(VC++ read line by line Txt text file, just a different way of reading and writing, in short, the ultimate goal is to read the entire document)
