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)

VC++中access与excel的交互的实现(VC++ in access and excel interactive )

对于文件外壳消除处理，对于生成的exe不可编译软件处理，能得到源码(VC size for BMP images)

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.)

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 )

可根据时间自动对指定的文件备份到指定的位置。(According to the time automatically to the specified file backup to the specified location.)

说明：  

利用MFC对Excel文件进行路径显示，写入，读取，更改，保存等操作 (Using MFC to read the Excel file, write, change, save and other operations)

一个快速读写DWG的文件源代码，DWG是矢量开发中经常碰到的文件格式，DWG文件格式比较烦琐，此库为程序员读写DWG文件节省很多精力(a fast read and write DWG document source code, Vector DWG development is frequently encountered in the paper format, DWG file format, and more than that, for this to read and write DWG programmers to save a lot of energy documents)

说明：  将不同文件类型文件打包为一个文件，并更改文件类型，供打包标记(Documents of different file types into a package file, and change the file type for packaging marking)
