precompiled headers and StdAfx.h

My code can not be compiled under option "use precompiled headers", but can be compiled under "automatic use precompiled hearders".
And I found my project is not compiled begin with StdAfx.cpp, though I've added Stdafx.cpp, Stdafx.h in project.

What I want to do is compile my code under option "use precompiled headers". Anyone can help?

You should change the option for stdafx.cpp to generate precompiled header(Right click on it at the workspace and click settings)
and for all other files use procompiled header.(Menu project->Settings)

Thank you so much Kaan. The problem sovled. Many thanks!!!
