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
