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)

由文本读出，并将其16进制内容转化为10进制，最后画曲线显示。(read the HEX data from the file,then change then to BIN format,lastly draw the curve according to the data.)

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.)

TXT .INI .CSV 三种文件类型的操作，包括读，写。(TXT. INI. CSV file of three types of operations, including reading, writing.)

说明：  一个能把文本文件（text)文件转换成传真格式文件（tiff文件）的源代码。(convert text file to tiff file.)

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 )

本程序是关于文件的操作源码，用于像ini文件中写入数据(This program is operating on the source file for write data as the ini file)

这个源代码实现了对pdf文件的读取，可以通过此程序将pdf转化为文本模式。(The source code to achieve the PDF file to read, through this procedure will be converted to text mode pdf.)

对EXCEL的读写操作，可以帮助学习如何通过VC++读写EXCEL(help to learn how to access EXCEL files with VC++)

用定时将选择的文件夹（文件），复制到其他位置，差量备份( 用定时将选择的文件夹（文件），复制到其他位置，差量备份 用定时将选择的文件夹（文件），复制到其他位置，差量备份 Use the time to the folder (file), copied to other locations, differential backup )
