can't hit breakpoint in asp project

I am using VS 2005 as an IDE for a classic ASP project (not asp.net). The files load fine into a project and all. It will run the page as well.

The problem that I am having is that when I place a breakpoint and run, I get a text tip saying that "the breakpoint will not currently be hit. No symbols have been loaded for this document". What gives?

I've gone through hell and high water trying to get interdev to debug, but it is nortoriously impossible to get it to cooperate with IIS.

I am assuming that vs.net is capable of debugging classic asp projects. If I am incorrect, please let me know so I can resume my suffering with interdev :))
If it is true, can you please help me getting this running and debugging?

Oh, by the way, this is a half completed project and I am not very familiar with asp.net so I'd rather not start over, just so ya know.

When i've had to do asp (not something I'm keen on) I have used Visual studio and as far as I know you can't step through asp code.

I wasn't even aware you could step through asp in interdev but i suppose you learn something new everyday and therefore i might be wrong about the above.

I have found a few examples on the web, but they are all using vs 2003, i am using 2005. There is a difference where they enable asp debugging. There is not a check box fot that in 2003. Hmm.......

Ah yes, the age old UFO of programming, debugging in ASP.

It is possible, but because ASP is so easy, and the fact that it's scripted, most ASP 3.0 developers don't even bother with debugging features of Interdev. Instead, they just use it with the attitude, "Hey, something came with VB6, so might as well use it for the syntax highlighting."

In fact, you can just code in notepad.

Anyways, it is possible, but on limited OSs. I know it wasn't possible in Win 98, but I had seen it on Windows 2000.
