From where can I get a classic asp editor?
I am partial to plain old notepad, but notepad++ offers some nice features.
I always use VS2008 (supports intellisense, highlighting and debugging from SP1) if I'm doing lots of changes, Notepad2 for quick ones (no intellisense, only highlighting)
Although I use VS for coding, in the same genre of Notepad++
Pretty colours, folding, logical projects and tons of other features.
It's the editor I use for opening existing asp code without the hassle of opening VS. (as asp code doesn't necessarily need a recompile)
I have always been a big fan of Dreamweaver for classic ASP. I really like the split screen view to see the code and the designer interface at the same time.
Visual Studio 2008 with the ability to do the split-screen view is also nice.
Although I used to use DreamWeaver or Notepad++, these days I like using VS2008. Mainly because you can attach to process and Debug your ASP code which, when I discovered it, caused me to do a merry jig around the office. You can even get some intellisense. (type Response. and it'll give you all the options .End .Write .Redirect etc..
I personally use TopStyle at work: http://svanas.dynip.com/topstyle/
In addition to classic ASP, it is pretty handy for HTML, CSS, Javascript with syntax highlighting, parens matching, etc.
I love Ultra edit for working on classic asp sites, but also any text editing it's great. Lightweight, fast, never crashes.
Only downside is you have to pay for it.
