Error Message unexpected end of file while looking for precompiled header. Did you forget to add '#include name' to your source? An include file specified with /Yu is not listed in the source file. This option is enabled by default in most Visual C++ Project types and "stdafx.h" is the default include file specified by this option.In the Visual Studio environment, use one of the following methods to resolve this error: If you do not use precompiled headers in your project, set the Create/Use Precompiled Header property of source files to Not Using Precompiled Headers. To set this compiler option, follow these steps: In the Solution Explorer pane of the project, right-click the project name, and then click Properties.In the left pane, click the C/C++ folder. Click the Precompiled Headers node.

This file also needs to be included before any other code in your source files using #include "stdafx.h". (This header file is specified as Create/Use PCH Through File project property)
缺省情况下，Visual studio 中的 .cpp 文件的第一行一般应当是 #include "stdafx.h"；如果你不是新手，另外谈。
#include "StdAfx.h"？
