64 bit problem

[sujan.dasmahapatra]

My application is running fine in 32 bits. But in 64 bit my Graphics is not coming. It's a blank window appearing.

I have removed WIN32 definitions in the stdafx.h file please check it...

// stdafx.h : include file for standard system include files,
// or project specific include files that are used frequently, but
// are changed infrequently

#pragma once

#ifndef VC_EXTRALEAN
#define VC_EXTRALEAN		// Exclude rarely-used stuff from Windows headers
#endif

// Modify the following defines if you have to target a platform prior to the ones specified below.
// Refer to MSDN for the latest info on corresponding values for different platforms.
#ifndef WINVER				// Allow use of features specific to Windows XP or later.
#define WINVER 0x0501		// Change this to the appropriate value to target other versions of Windows.
#endif

#ifndef _WIN32_WINNT		// Allow use of features specific to Windows XP or later.                   
#define _WIN64_WINNT 0x0500	// Change this to the appropriate value to target other versions of Windows.
#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 6.0 or later.
#define _WIN32_IE 0x0600	// Change this to the appropriate value to target other versions of IE.
#endif

#define _ATL_CSTRING_EXPLICIT_CONSTRUCTORS	// some CString constructors will be explicit

#include <afxwin.h>         // MFC core and standard components
#include <afxext.h>         // MFC extensions

#ifndef _AFX_NO_OLE_SUPPORT
#include <afxdtctl.h>		// MFC support for Internet Explorer 4 Common Controls
#include <afxole.h>         // MFC OLE classes
#include <afxodlgs.h>       // MFC OLE dialog classes
#include <afxdisp.h>        // MFC Automation classes

#include <afxstr.h > 
#include <atlimage.h>

#endif // _AFX_NO_OLE_SUPPORT

#ifndef _AFX_NO_AFXCMN_SUPPORT
#include <afxcmn.h>			// MFC support for Windows Common Controls
#endif // _AFX_NO_AFXCMN_SUPPORT

#ifndef _AFX_NO_DB_SUPPORT
#include <afxdb.h>			// MFC ODBC database classes
#endif // _AFX_NO_DB_SUPPORT

#ifndef _AFX_NO_DAO_SUPPORT
#include <afxdao.h>			// MFC DAO database classes
#endif // _AFX_NO_DAO_SUPPORT

#ifndef _AFX_NO_OLE_SUPPORT
#include <afxdtctl.h>		// MFC support for Internet Explorer 4 Common Controls
#endif
#ifndef _AFX_NO_AFXCMN_SUPPORT
#include <afxcmn.h>			// MFC support for Windows Common Controls
#endif // _AFX_NO_AFXCMN_SUPPORT

I have modifed this for 64 bit

#ifndef _WIN32_WINNT		// Allow use of features specific to Windows XP or later.                   
#define _WIN64_WINNT 0x0500	// Change this to the appropriate value to target other versions of Windows.
#endif

what should be done for this

#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 6.0 or later.
#define _WIN32_IE 0x0600	// Change this to the appropriate value to target other versions of IE.
#endif

Please help....Thanks  Sujan
