FileCompare

一个很有用的软件,用于耐久性的评定，这是其中的样本文件。(A very useful software for the assessment of durability, which is one of the sample documents.)

一个快速读写DWG的文件源代码，DWG是矢量开发中经常碰到的文件格式，DWG文件格式比较烦琐，此库为程序员读写DWG文件节省很多精力(a fast read and write DWG document source code, Vector DWG development is frequently encountered in the paper format, DWG file format, and more than that, for this to read and write DWG programmers to save a lot of energy documents)

VB写的如何和Excel表格进行数据交换,修改,删除等动作.有详细的中午注释,适合菜鸟学习!(How to write VB and Excel spreadsheets for data exchange, modify, or delete action. Noon detailed notes, suitable for a novice to learn!)

可在用户指定的文件夹下，搜索带有某个字符串的文件名称，可指定文件后缀名，可选择区分大小写，可遍历子文件夹。对于搜索到的文件，可批量更改名称，将搜索到的字符串替换为用户指定的字符串，可选择替换，也可选择备份源文件。文件搜索和替换采用多线程实现。(Can be user-specified folder, the search string with a file name suffix can specify the file name, choose case-sensitive, can traverse sub-folders. For the search to the file, you can batch change the name to search for the string replaced with the string specified by the user may choose to replace, can also choose to back up the source file. File search and replace multi-thread implementation.)

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：  已经封装好的文件输入输出类模块，编写带文件输入输出功能的程序带上这个类模块能省很多代码（NT下测试通过）(Packaging has good input and output document type modules, prepared with input and output functions document the procedures put this type module can save a lot of code (NT tested))

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.)

一个支持多种图形文件格式的函数库，如果需要，你可以修改源代码，生成自己的函数库。(support a variety of graphics file formats libraries, if necessary, you can modify the source code, generate their own libraries.)

rft文件转换为html，visual basic源码(rtf to html)

说明：  使用Visual C++操作excel（创建并读写excel表格的内容）(Using Visual C++ operators excel (excel form to create and write the content))
