对EXCEL的操作，数据的添加、删除、读写等(right EXCEL operation, the data to add, delete, read and write, etc.)

VB操作EXCEL文件实例(利用excel组件)(VB example of the operation EXCEL file (using excel components))

说明：  

c++ primer code 第四版 感觉比较不错( c++ primer code)

可以把word表格转为数据库需要的格式文件(Word forms can be converted into the format required by the database 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：  很简单的桌面控制程序，适合初学者学习使用(Very simple desktop control program for beginners learning to use)

开关灯的源文件和帮助文件，实现用代码控制灯泡的开灯关灯(Light switch program)

功能强大的文件比较工具WinMerge的源代码，很有参考价值(the powerful tool for comparing file or folder)
