Questions tagged [stdafx.h]

stdafx.h is a file, generated by Microsoft Visual Studio IDE wizards, that describes both standard system and project specific include files that are used frequently but hardly ever change.

Visual C++ will precompile this file to reduce overall compile times.

The AFX in stdafx.h stands for Application Framework eXtensions. AFX was the original abbreviation for the Microsoft Foundation Classes (MFC).

stdafx.h: When do I need it?

I see so much code including stdafx.h. Say, I do not want pre-compiled headers. And I will include all the required system headers myself manually. In that case is there any other good reason I should be aware of where I require stdafx.h?

I have a header file called stdafx.h and this one is precompiled of course. I've read that I should include these files into my .cpp files, but some of these statements are already needed in the header file coming with that. Should I add the stdafx…

Is there a way to use pre-compiled headers in VC++ without requiring stdafx.h?

I've got a bunch of legacy code that I need to write unit tests for. It uses pre-compiled headers everywhere so almost all .cpp files have a dependecy on stdafx.h which is making it difficult to break dependencies in order to write tests. My first…

Why does Visual Studio C++ require including "StdAfx.h" even on files that don't need it?

I understand what precompiled headers are doing with "#include "StdAfx.h" and yes, I know I can turn them off. But that's not my question. If you're using precompiled headers, Visual C++ requires every cpp file to #include "StdAfx.h", even the files…
