MFC Loading link library (DLL) errors

I'm using a VS2010.

When using WMI to obtain computer system information, use the DLL to the win system,

Error 1:

Error message: Err 1error C1189: #error: Building MFC Application With/md[d] (CRT DLL version) requires MFC s hared DLL version. Please #define _afxdll or does not use/md[d]f:\vs2010u\vc\atlmfc\include\afx.h1 Wmitest

Cursor position: In the Afx.h file

#ifdef _dll
#ifndef _afxdll
#error Building MFC Application With/md[d] (CRT DLL version) requires MFC shared DLL version. Please #define _afxdll or does not use/md[d]
#endif
#endif

Workaround:

Project---->properties---->configuration propertes---->general----> Project Defaults----> use of MFC- ---> Check the use of MFC in share DLL

Error 2:

Workaround:
