Trying to port console application to MFC GUI, but have issues with stdafx

So the console application works fine as a console application. Now I created a MFC GUI application and the dialog itself works fine. When i add the console application files to the MFC project, it complains about how stdafx.h is missing from the console application's files. Now I know I should a开发者_如何学运维dd #include "stdafx.h" to the top of the cpp files, but there's just so many of them and the program worked fine without it. There is no MFC in the console application files so I don't see why I need to include it. I tried turning off precompiled headers, but it takes longer to compile. How do I allow precompiled headers, but turn it off for selected files?

If you bring up the Properties sheet when you have a file in File View selected, you can enable or disable precompiled headers for that file.
