How to edit a precompiled vb.net web app?

[manared]

Hello, quick question hopefully. I was asked to check over and change a web app that was created in vb.net 2003. I am currently using 2005, so I would have to convert it, which is fine cuz that always does it automatically. When I try opening this particular app, I get this:
Y
ou are attempting to open a precompiled web site. You can view the site, but changes might cause the site to stop functioning. To modify a site, it is recommended that you edit the files in the original website, precompile the site, and then publish it again.

When I click yes, it opens the program, but I cannot see any of the code behind. It's like there aren't any aspx.vb pages. How am I able to upload and change this program so it can work again? Thank you!!!

You need the original project. If you are just using the compiled DLLs, then this will not work for you. You need the actual source code for the application. Is like trying to open and EXE with a compiler and expecting to see the source code that makes the EXE up. Not possible without the original project (at least not without reverse engineering the application)
