How to implement precompiled headers into your project

Question

I understand the purpose and reasoning behind precompiled headers. However, what are the rules when implementing them? From my understanding, it goes something like this:

Answer 1

You stdafx.cpp should include stdafx.h and be built using /Yc"stdafx.h".

Your other *.cpp should be include stdafx.h and be built using /Yu"stdafx.h".

Note the double-quote characters used in the compiler options!

Here's a screenshot of the Visual Studio settings for stdafx.cpp to create a precompiled header:

Here are the corresponding command-line options (which are read-only but reflect the settings specified on other pages; note that the IDE inserts double-quote characters around the filename, in the compiler option):

This is what's in my stdafx.cpp file:

// stdafx.cpp : source file that includes just the standard includes
// CallWinsock.pch will be the pre-compiled header
// stdafx.obj will contain the pre-compiled type information

#include "stdafx.h"

// TODO: reference any additional headers you need in STDAFX.H
// and not in this file
