how to edit vb code in code behind file?

I have a compiled website and now I need to make some changes to the code behind vb file. When I open a website in Visual Studio it gives me a message "You are trying to open a precompiled website." I have tried several different things but it does not recognize any changes I make to code behind file. I don't have any experience with code behind file so I am not sure what to do. When I build it, it says its recompiled and when I try to publish, it gives me a list of errors (errors posted in jpeg file). I would really appreciate any help.

Well, but do you have the original files for the website, or are you trying to edit the code behind for the site that was running (already compiled)?. If you don't have the original files, I don't think that you will be able to change the code behind code, since it's compiled. You need to have the original files.

I guess you could try:
Was that project originally done in VS 2005???

Did you try following the suggestion on the first line of the error list???

it was originally done in VS 2005 I believe. I haven't followed the first line since I am not sure how to. Also, this code is a copy of a working website which my company is using right now.
