"Error C1083: Cannot open source file" Shouldn't Be Looking For The File At All

Question

I was trying to #include a cpp file with some functions so I can use that cpp file later with other projects. It gave me an 'already defined in .obj' error and since then that .cpp file was like binded with my project. (I understood that's not the way, the answer here helped me with the already defined)

If I exclude the .cpp file from the project, remove it from the directory and remove the #include line it still looks for it:

c1xx : fatal error C1083: Cannot open source file: 'std.cpp': No such file or directory

Diagnostic:

Outputs for D:\MY DOCUMENTS\C#\PROJECT\D3DTESTC++\COWS AND BULLS\CBMAIN.CPP|D:\MY DOCUMENTS\C#\PROJECT\D3DTESTC++\COWS AND BULLS\STD.CPP: (TaskId:15)

It shouldn't be looking for the std.cpp at all, I removed it! So is there a way I can reset the project and recompile so that the program doesn't look for it? I already tried Rebuild and Clear -> Build Project

Answer 1

When I ran across a similar problem with VS Express, I wound up having to open up the the .vcxproj file (which is just XML), and remove the offending < ClInclude Include="FILEPATHANDNAME" > tags.
