    哈夫曼文本压缩器,两个功能压缩文本文件和解压二进制文件。 内容为源代码,用编译器把源代码运行一遍,把需要压缩的txt文件放到和源代码同一个目录下,压缩名称输入 **.txt 压缩后的名称一定要写二进制格式的 例如 **.dat 只能解压用这个程序压缩后的文件。。 解压名 写 **.dat 解压后名称 **.txt(Huffman text compression, two text files compression and decompression functions binaries)

  • GZIP例子
    说明:  利用gzip.dll解压http请求返回的内容。内附gzip.dll。参考网上资料自己写的VB6工程源码。自己编译EXE的时候注意把gzip.dll释放到exe所在目录。(Use gzip.dll to decompress the content returned by HTTP request. Gzip.dll is attached. Refer to the VB6 project source code written by myself.)
