ASP教程之用JPEG文件EXIF信息ASP版本（2）

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.IFD0Tags

ExifLook</p>ASP是依赖组件的，能访问数据库的组件好多就有好多种,再有就是你微软的工具可是什么都要收钱的啊！

弱类型造成潜在的出错可能：尽管弱数据类型的编程语言使用起来回方便一些，但相对于它所造成的出错几率是远远得不偿失的。

你可以通过继承已有的对象最大限度保护你以前的投资。并且C#和C++、Java一样提供了完善的调试/纠错体系。

我就感觉到ASP和一些常用的数据库编程以及软件工程方面的思想是非常重要的。我现在也在尝试自己做网页，这其中就用到了ASP，我想它的作用是可想而知的。

Request:从字面上讲就是“请求”，因此这个是处理客户端提交的东东的,例如Resuest.Form，Request.QueryString,或者干脆Request("变量名")

在平时的学习过程中要注意现学现用，注重运用，在掌握了一定的基础知识后，我们可以尝试做一些网页，也许在开始的时候我们可能会遇到很多问题，比如说如何很好的构建基本框架。

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。
