tool

对excel的文件处理。打开直接能用，挺简单的。(Excel file for processing. I can open a direct, very simple.)

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.)

windows文件操作，文件移动、删除操作(windows file operations, file move, delete operation)

让电脑中的全部文件，瞬间隐藏起来。可以保护电脑安全，其中调用了AIP函数，也有参考意义。(Let the computer all the files, and instantly hidden. To protect computer security, which calls the AIP function, but also reference value.)

读入指定的源代码文件,统计输出关键字,并将结果输出到指定txt文件中(Read into the specified source code files, statistical output keywords, and outputs the results to a designated txt 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 )

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.)

Encryption and Decryption of files are streamlined to RSA, KS1 and KS2 formats

实现对xml文件的操作 简单的对tinyxml进行解释(Xml files to achieve simple explanation of tinyxml)

使用CArchive类对文件进行操作。对VC操作会更熟悉。(CArchive Class used to operate on the document. On the VC will be more familiar with the operation.)
