I´ve got in front of my eyes a project build by another guy and it is develo开发者_如何学JAVAped in ASP (not ASP.NET) so I opened it with Visual Web Developer 2010 and I can edit but it isn´t posible to debug it step by step, it´s always looking for aspx pages...

do you know any other editor for asp? thanks!

I use Visual Studio 2010 to debug ASP pages

First configure IIS as follows ...

1. Go to IIS Manager
2. Switch to Features View
3. Double-click ASP (under IIS heading)
4. Open up the Debugging Properties section
5. Set Enable Server-side Debugging to True

To debug your ASP page ...

1. Run your website without debugging it
2. Wait for your web browser appears
3. In VS select Attach to Process... from the Debug menu
4. Tick the Show processes in all session box (below the list of Available Processes)
5. Find the w3wp.exe process (it's the one with Script, T-SQL, Managed, x86 in the Type column)
6. Click the Attach button
7. Set your breakpoint
8. ..................................reproduce the problem

Now, this is in full Visual Studio, but it may work in the express edition.
