stdafx.h: When do I need it?

Question

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 m

Answer 1

You can use pre-compiled headers (which are a good thing) without using stdafx.h (I abominate it too). I've only got access to VC++ 6.0 but in that go to Project Settings|C/C++|Precompiled Headers and select "automatic use of precompiled header" but leave the "compiled through" box empty.
