在使用一些新版本的API，或者控件的新特性（比如新版的ComCtl32.dll）的时候,你可能会得到“error C2065: undeclared identifier.“这个错误。原因是这些功能是依赖于你的操作系统的版本的。而你的头文件中的定义并不是最新的。（对于MFC,就是stdafx.h）下面详细列举了每个Windows版本对应的 NTDDI_VERSION， _WIN32_WINNT， WINVER， _WIN32_IE这些宏。

 

The following table describes the preferred macros in use by the Windows header files.

Minimum system required                Macros to define
Windows Server 2008                     NTDDI_VERSION >= NTDDI_LONGHORN
Windows Vista                                NTDDI_VERSION >= NTDDI_VISTA
Windows Server 2003 SP1                 NTDDI_VERSION >= NTDDI_WS03SP1
Windows Server 2003                     NTDDI_VERSION >= NTDDI_WS03
Windows XP SP2                          NTDDI_VERSION >= NTDDI_WINXPSP2
Windows XP SP1                          NTDDI_VERSION >= NTDDI_WINXPSP1
Windows XP                                  NTDDI_VERSION >= NTDDI_WINXP
Windows 2000 SP4                        NTDDI_VERSION >= NTDDI_WIN2KSP4
Windows 2000 SP3                        NTDDI_VERSION >= NTDDI_WIN2KSP3
Windows 2000 SP2                        NTDDI_VERSION >= NTDDI_WIN2KSP2
Windows 2000 SP1                        NTDDI_VERSION >= NTDDI_WIN2KSP1
Windows 2000                                NTDDI_VERSION >= NTDDI_WIN2K

The following table describes the legacy macros in use by the Windows header files.
