c++ - 错误 C1189 : #error : This file requires _WIN32_WINNT to be #defined at least to 0x0500. 建议使用值 0x0501 或更高

Question

我在 VS2010(windows xp) 中创建 MFC 项目。我接受了这个错误:

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

如果我在 afxcomctl32.h 中添加:#define _WIN32_WINNT 0x0501，我会出现 60 多个错误。 在项目中我没有添加任何东西。使用诸如 Visual Studio 创建的。 我需要用这个做什么？

我认为 afxcomctl32.h 是一个错误的地方，要解决这个问题，请使您的 stdafx.h 看起来像这样:

// 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
