仿WinRar解压缩VB版 这个示例就是利用这个动态链接库进行的一些操作，但目前还没有压缩文件的功能，里面的dll函数接口还需要进一步的解析和查找资料，官方好像也没有提供，希望有知道的网友也可以提供一下。更希望感兴趣的网友继续进行挖掘和开发。 源代码附有详细的注释和文档说明。使用前请把压缩包里的 UnRar.dll拷贝到你的计算机的系统文件夹下，如 WindowsSystem32下。-WinRar imitation extract VB version of this example is the use of the dynamic link library to carry out some operation, but it has not been compressed files, inside the dll interface function need further analysis and search for information, the official did not seem to offer hope to have users know that you can provide. Also hope that users are interested in continuing to carry out excavation and development. Source code with detailed notes and documentation. Please use the pre-compression of the bag UnRar.dll copy to your computer s System Folder, such as under WindowsSystem32.

编程实现帧封装。帧封装只是在数据的头和尾上加特定的二进制数据，可以直接用读写二进制文件的方式读出来，然后把该加的头尾写进去就行了。 -Programming frame package. Encapsulated only in the data frame the head and tail add a specific binary data, you can read and write binary files directly read out the way and then the beginning and end of the added inclusion of opinions on line.

此为基于二代提升小波的阈值压缩算法源码，其中可以设置小波变换的分解层数，使用的小波名称，及各层阈值设置计算公式中的参数。并将低频系数转化为十六进制，方便在其上进一步压缩，如采用Huffman压缩等，程序思路清楚，附有完整的注释，可以使用多种小波，并且很好得体现了二代小波的思想，对于初学小波者帮助很大。-based on the second generation of this upgrade wavelet compression algorithm threshold source, which can set wavelet transform decomposition level, the use of wavelet name, threshold levels and set the formula for calculating the parameters. And low-frequency coefficients into hexadecimal facilitate its further compression, such as the Huffman compression. procedures ideas clearly, with the integrity of the Notes, you can use a variety of wavelet, and reflected very well in the second generation wavelet thinking, For beginners who wavelet of great help.
