fatal error C1189: #error : This file requires _WIN32_WINNT to be #defined at least to 0x0403

\microsoft visual studio 10.0\vc\atlmfc\include\atlcore.h(35): fatal error C1189: #error :  This file requires _WIN32_WINNT to be #defined at least to 0x0403. Value 0x0501 or higher is recommended.

此错误一般在 低版本 向高版本转换，比如我现在 用vs2010 打开vs2008时出问题

解决办法  在 stdafx.h 中注释掉以下内容

#ifndef WINVER // Allow use of features specific to Windows 95 and Windows NT 4 or later.
//#define WINVER 0x0400 // Change this to the appropriate value to target Windows 98 and Windows 2000 or later.
//#endif
//
//#ifndef _WIN32_WINNT // Allow use of features specific to Windows NT 4 or later.
//#define _WIN32_WINNT 0x0400 // Change this to the appropriate value to target Windows 98 and Windows 2000 or later.
//#endif
//
//#ifndef _WIN32_WINDOWS // Allow use of features specific to Windows 98 or later.
//#define _WIN32_WINDOWS 0x0410 // Change this to the appropriate value to target Windows Me or later.
//#endif
//
//#ifndef _WIN32_IE // Allow use of features specific to IE 4.0 or later.
//#define _WIN32_IE 0x0400 // Change this to the appropriate value to target IE 5.0 or later.
//#endif
