Visual C++(MFC Project) link to MySQL

the .h including codes are :

#include <mysql++.h>
#include <mysql.h>

#include <afxwin.h>         // MFC core and standard components
#include <afxext.h>         // MFC extensions
#include <afxdisp.h>        // MFC Automation classes
#include <afxdtctl.h>            // MFC support for Internet Explorer 4 Common Controls
#ifndef _AFX_NO_AFXCMN_SUPPORT
#include <afxcmn.h>                  // MFC support for Windows Common Controls

I guess mysql++.h includes windows.h that conflicts with afxwin.h, which has to be included at MFC application project. But i do not know how to solve this problem. Could someone help me?
