Remarks

The Shell_GetCachedImageIndexA and Shell_GetCachedImageIndexW versions of this function were added in Windows Vista. For Unicode strings, call either Shell_GetCachedImageIndexW or Shell_GetCachedImageIndex. For ANSI strings, you must call Shell_GetCachedImageIndexA explicitly.

Windows Server 2003 and Windows XP:  Only Shell_GetCachedImageIndex is supported. Shell_GetCachedImageIndex requires a Unicode string.

Note

The shlobj_core.h header defines Shell_GetCachedImageIndex as an alias which automatically selects the ANSI or Unicode version of this function based on the definition of the UNICODE preprocessor constant. Mixing usage of the encoding-neutral alias with code that not encoding-neutral can lead to mismatches that result in compilation or runtime errors. For more information, see Conventions for Function Prototypes.
