Some downloaded files don't compile, unless you add #include "stdAfx.h"

Very often you get the compiler message :
fatal error C1010: unexpected end of file while looking for precompiled header. Did you forget to add '#include "StdAfx.h"' to your source?

Your downloaded Ex_xx.cpp is right, but you need to change the default compiler option :
1.Open the project's Property Pages dialog box. For details, see Setting Visual C++ Project Properties.
2.Click the C/C++ folder.
3.Click the Precompiled Headers property page.
4.Modify the Create/Use PCH Through File property or the Create/Use Precompiled Header property

The default setting of VS2010 is :
Visual C++ will not compile anything before the #include "stdafx.h" in the source file.

The answer to this post is EXACTLY the question I had. I've used Express 2008, but Express 2010 seems to be quite different. Also, I keep getting the Compiler error, "Fatal Error External Refernce not found." Perhaps this is part of the same issue as stdAfx.h inclusion.
I think I shall like this forum.
Thanks much!
