ASP网页编程之解密ASP源代码

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.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..

由于ASP还是一种Script语言所没除了大量使用组件外，没有办法提高其工作效率。它必须面对即时编绎的时间考验，同时我们还不知其背后的组件会是一个什么样的状况；

没有坚实的理论做基础，那么我们连踏入社会第一步的资本都没有，特别对于计算机专业的学生学好专业知识是置关重要的。在这里我侧重讲一下如何学习ASP，从平时的学习过程中。

接下来就不能纸上谈兵了，最好的方法其实是实践。实践，只能算是让你掌握语言特性用的。而提倡做实际的Project也不是太好，因为你还没有熟练的能力去综合各种技术，这样只能使你自己越来越迷糊。

不是很难但是英文要有一点基础网上的教程很少有系统的详细的去买书吧,另不用专门学习vb关于vbscript脚本在asp教材都有介绍

跟学别的语言一样，先掌握变量，流程控制语句(就是ifwhileselect)等，函数/过程，数组

不能只是将它停留在纸上谈兵的程度上。

如何学好ASP,以前也有人问过,把回答给你转过来看看能否对你有帮助:

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。

以上是语言本身的弱点，在功能方面ASP同样存在问题，第一是功能太弱，一些底层操作只能通过组件来完成，在这点上是远远比不上PHP/JSP，其次就是缺乏完善的纠错/调试功能，这点上ASP/PHP/JSP差不多。
