ASP编程：怎样解密加密的ASP源代码

ASP一般认为只能运行在IIS上，正如前面所提到的，这并不是十分正确，事实上，ASP也能运行在Apache上。ApacheASP可在任意Apache服务器上运行有限的ASP功能，所需做的，只需打开mod_perl。加密|解密|源代码从网上兴趣冲冲地下载了ASP源代码,筹办进修研讨的时分.一翻开文件,天书般的加密代码.很让人忧郁吧:(
在网上是找到懂得密的办法,得一个文件挨一个文件地翻开,复制,粘贴,解密,再复制,再粘贴,再保留......
假如一个ASP程序有几百个文件???
办理举措来了..

问题是他们究竟是喜欢他们是使用软件时,速度快还是速度慢好.(当然在3秒以内).无论是他们输入资料时,查找资料时,分析资料时.

封装性使得代码逻辑清晰，易于管理，并且应用到ASP.Net上就可以使业务逻辑和Html页面分离，这样无论页面原型如何改变，业务逻辑代码都不必做任何改动；继承性和多态性使得代码的可重用性大大提高。

我可以结合自己的经验大致给你说一说，希望对你有所帮助，少走些弯路。

代码逻辑混乱，难于管理：由于ASP是脚本语言混合html编程，所以你很难看清代码的逻辑关系，并且随着程序的复杂性增加，使得代码的管理十分困难，甚至超出一个程序员所能达到的管理能力，从而造成出错或这样那样的问题。

ASP.Net摆脱了以前ASP使用脚本语言来编程的缺点，理论上可以使用任何编程语言包括C++,VB,JS等等，当然，最合适的编程语言还是MS为.NetFrmaework专门推出的C(读csharp)，它可以看作是VC和Java的混合体吧。

ASP主要是用好六个对象，其实最主要的是用好其中两个：response和request，就可以随心所欲地控制网页变换和响应用户动作了。

ASP.Net和ASP的最大区别在于编程思维的转换，而不仅仅在于功能的增强。ASP使用VBS/JS这样的脚本语言混合html来编程，而那些脚本语言属于弱类型、面向结构的编程语言，而非面向对象，这就明显产生以下几个问题：
