讲解在线压缩和解压缩的ASP实现方法
在线压缩/在线解压缩是一个很实用的东东，今天就为大家实例讲解一下如何用asp来实现：
<%
’\\\\\\\\\\\\\\\\\\\\\\\\\\\\\
’\
’\ 1. c:windowssystem32cmd.exe
’\ 拷贝把本文件所在的路径
’\
’\ 2. 把 c:programwinrarar.exe
’\ 拷贝把本文件所在的路径 并改名为winrar.exe
’\
’\\\\\\\\\\\\\\\\\\\\\\\\\\\\\
’\
’\ compresspath(byval s)
’\ 压缩文件的路径 | 字符串变体
’\
’\ decompresspath(byval s)
’\ 解压缩文件的文件夹 | 字符串变体
’\
’\ compress
’\ 在线压缩
’\
’\ decompress
’\ 在线解压缩
