First question, is this classic asp, 1.0, 1.1, 2.0, 3, 3.5, 4, 4.5? It makes a big difference for us to know this. Elina's answer is exactly correct for anything 2 or above, but for classic, 1.0, or 1.1 debugging is not kicked off in the same way. I suspect that your solution will lie in Elina's answer, though.

You can attach to the process for debugging.
To do that:
1. Open page in browser (http://localhost/yourPage.apx)
2. In Visual studio go to debug -> attach to process -> w3wp.exe


you may need to open Visual studio as administrator in order to do that
