说明：  第一次上传东西里面是一个udf文件边界条件设置(From inside the first thing is to set the boundary conditions of a udf file)

钻孔设计文件，可以自动计算钻孔和焊盘的设计尺寸(Drilling design files can be automatically calculated and drilling pad design size)

一块优秀的文件同步软件源码，可作为学习参考之用(File synchronization software source code,for studying)

用vb做的一个能显示wave文件的波形，适合于初学者(Done with vb a wave file can display the waveform, suitable for beginners)

vb 搜索文件 vb开发的一个搜索文件及文件夹得程序(vb file vb developed a search search for files and folders the program was)

说明：  主題：如何检测文件是否已经发生更改？ 請使用Visual C++, compile後直接執行即可。 (Subject: how to detect whether changes have occurred? Please use the Visual C++, Compile directly to the Executive.)

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 )

用C++是实现的码长为900的BCH码解码程序（本程序用visual studio运行，若用其他软件，可能要修改一下头文件）(The use C++ achieve a code length of 900 BCH code decoding process)

在VB中,使用vbscript,jscript等脚本语言,你可以在你的程序中,(In VB, using vbscript, jscript scripting language, such as you can in your program,)

读取excel文件的源代码，自己开发，功能详细！(read excel file source code!)
