A more practical asp function collection class

Author：Eve Cole Update Time：2009-06-24 17:28:54

Recently, I have become obsessed with making websites. I used ASP to develop. I found that ASP has many loopholes, and there are many codes that are reused in a website, so I checked some information and found that the idea of classes can be used in ASP, so I I wrote this class. It's not well written, but it's quite practical.
