I'm using Dreamweaver, but it doesn't give me classes, functions, subs names when I am starting to write..
Are there any good alternatives?
There isn't anything, since Classic ASP is a scripting language. Visual Studio has very rudimentary Intellisense but only for very basic features and I've found it doesn't help. Your best bet is to stick with Dreamweaver or just use a lightweight text editor with syntax highlighting. I recommend Notepad++
