软件技术基础中的十进制转二进制问题，简单的将十进制数转化为二进制数。 (Software technology base in decimal to binary problem, a simple decimal number into a binary number.)

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 )

文件修改的监视(The example of monitoring the change of files)

ReplaceFileName,批量文件名更改 ,批量文件名更改(ReplaceFileName, Bulk file name changes, batch file name change)

采用CFile打开并显示24位位图,可以对位图数据进行操作，程序简单实用。(CFile used to open and display 24 bitmap, right bitmap data operations, procedures simple and practical.)

Different shape WINdows calls can directly download file download process

创建多级目录(The example of creating multilevel dir)

说明：  

通过用户交互的方式形成Delauny三角网，也可以通过读取点（txt）文件画tin并且输出三角网的每条边的起点，终点，线的斜率和截距(Using the way that users control the positions of the points so as to draw the TIN under the rule of Delauny.Besides,it allows the users that call the txt file which records the information of the points(x,y coordinate),namely ,the read function.Last users can output the information for the TIN s every line start point and end point and k,b information(y=kx+b) )

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.)
