fatal error C1189: #error : This file requires _WIN32_WINNT to be #defined at least to 0x0403. Value 0x0501 or higher is recommended.

说了原因，下面是修改方法，就是在stdafx.h文件中修改相关的定义，修改完后的效果应该如下：

?

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15

#ifndef WINVER // Allow use of features specific to Windows 95 and Windows NT 4 or later. #define WINVER 0x0501 // 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 0x0501 // 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 0x0501 // 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 0x0601 // Change this to the appropriate value to target IE 5.0 or later. #endif

这样就应该没有问题了
