从网上兴致冲冲地下载了ASP源代码,准备学习研究的时候.一打开文件,天书般的加密代码.很让人郁闷吧 :( 在网上是找到了解密的方法,得一个文件挨一个文件地打开,复制,粘贴,解密,再复制,再粘贴,再保存......如果一个ASP程序有几百个文件??? 
解决办法来了..
复制代码代码如下:

<% @Language="JavaScript" %>

/*

* 功能:遍历某个目录下的所有文件,对加密过的.asp文件 
* 进行解密,并写入源文件中. 
* 实例:单个文件解密 
* Response.Write(DncodeFile(Server.MapPath("conn.asp"))); 
* 实例:目录下所有文件解密. 
* DncodeFolderFiles(Server.MapPath("xml")) 
* author:wanghr100(灰豆宝宝.net) 
* update:2004-5-17 11:31 
*--------------- decode.asp -----------------

function DncodeFile(sFilePath) 

/*

f.Close(); 
sDncodeText = strdec(sFileText) 
var f = fso.OpenTextFile(sFilePath,ForWriting,true); 
f.Write(sDncodeText); 
f.Close(); 
//return sDncodeText; 
return sFilePath;

/*

/* Add 2004-5-17 11:09 只为一维数组 */

return sFilePath;
