Just start to test a VS.net 2002 project for ASP.net application.
After successfully installed the VS.net 2002 and tested the
IIS 5.1 on XP Pro SP2 for some classical
ASP programs, I started to build ASP.net programs.

For a new ASP.net project, an error message (i.e Unable to start
debugging on the web server) popped out. I disabled the ASP.net
debugging for 3-4 projects. However, I either could not see the
ASP.net Server-side design page, or could not run the
Server-side codes/buttons.

I did re-install VS.net 2002 twice; but the error message is still the
same. The complete error message is:

Error while trying to run project: Unable to start debugging on the
web server. The server does not support debugging of ASP.net or
ATL Server applications. Run setup to install the VS.net server
environment. If setup has been run verify that a valid URL has been
specified.
You may also want to refer to the ASP.net and ATL Server debuggiong
topic in the online documentation. Would you like to disable future
attempts to debug ASP.net pages for this project? Yes. No, Help?

My questions: 1. On the Debug menu, there are two commands, Start and
Start w/o debug. What's the difference between these two commands?
Can we run ASP.net programs without debugging the codes first?
2. How can I start VS.net 2002 debugging on my IIS 5.1?

TIA,
Jeffrey

Start w/o debugging means that the code will ingore any hooks you place in code so, if you have a section of problematic code and want to see whats going on in it, you will not be able to step into it.

I have had this problem before, but, only when working with a remote server. The one time I had this problem with my machine, it had to do with the fact that I had 2 versions of .NET installed in IIS 1.1 and 2.0.

The directory that had my application (designed in 1.1) was configured to execute with the 2.0 framework and Visual Studio couldn't start debugging on my project because of this. I configured the directory to run under 1.1 and everything worked fine.

Visual Studio should give you links to the MSDN when you get that error, read EVERYTHING on that page because there are multiple reasons why this would fail.

Thanks.

How do I know my ASP.net applications is configured to execute with the right version of .NET Framework? Where to review the directory to run under ?

TIA,
Jeffrey

Bring up the properties of the virtual folder or website in IIS there is a tab that says ASP.NET there will be a drop down box on that page that contains all versions of the framework installed on the machine. you can select the version you want to use from there.

I could not see the ASP.net tab on my IIS adm desktop. I finally solved the problem. VS.net 2002 can not use .NETFramework 1.1. I had to use regiis.exe to create the mapping for my VS.net 2002 to NetFrameowrk 1.0.

Thanks for the information.
