error C1189: #error : This file requires _WIN32_WINNT to be #defined at least to 0x0500. Value 0x0501 or higher is recommended

Question

I create MFC project in VS2010(windows xp). And i take this error:

error C1189: #error : This file requires _WIN32_WINNT to be #defined at least to 0x0500. Value 0x0501 or higher is recommended. 

if I added in afxcomctl32.h: #define _WIN32_WINNT 0x0501, i take 60+ errors. In project i dont added anything. Use such as Visual Studio created. What i need to do with this?

afxcomctl32.h is a wrong place I think, to fix this problem make your stdafx.h looking like this:

// 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 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 0x0500    // Change this to the appropriate value to target IE 5.0 or later.
#endif

Solution 2

Try adding this to the TOP of your StdAfx.h file:

#include <sdkddkver.h>

In my application, I'm defining

_WIN32_WINNT=_WIN32_WINNT_WINXP

At first I had the same problem. I discovered that because when you use MFC, you're not allowed to include windows.h, _WIN32_WINNT_WINXP is never defined and so _WIN32_WINNT didn't have a valid value. By including the header that windows.h uses to define those values (sdkddkver.h), suddenly everything works!

Blech. I hate programming for Windows.

Solution 3

You don't need to modify afxcomctl32.h. You just need to include Windows.h before this file.

Should work.

Sure you have pasted this on the very first place in stdafx.h?

Works for me! thanks @duDE! (now, that's is an affirmative username!)
