在用WMI获取电脑系统信息时，要使用到win系统的dll,

错误1：

错误提示：Error 1error C1189: #error :  Building MFC application with /MD[d] (CRT dll version) requires MFC shared dll version. Please #define _AFXDLL or do not use /MD[d]f:\vs2010u\vc\atlmfc\include\afx.h241 WMITest

光标位置：afx.h文件中的

#ifdef _DLL
#ifndef _AFXDLL
#error Building MFC application with /MD[d] (CRT dll version) requires MFC shared dll version. Please #define _AFXDLL or do not use /MD[d]
