HIGHCONTRASTA structure (winuser.h)
Contains information about the high contrast accessibility feature.This feature sets the appearance scheme of the user interface for maximum visibility for a visually-impaired user, and advises applications to comply with this appearance scheme.
Syntax
typedef struct tagHIGHCONTRASTA {
UINT cbSize;
DWORD dwFlags;
LPSTR lpszDefaultScheme;
} HIGHCONTRASTA, *LPHIGHCONTRASTA;
Members
cbSize
Type: UINT
Specifies the size, in bytes, of this structure.
dwFlags
Type: DWORD
Specifies a combination of the following values:
lpszDefaultScheme
Type: LPTSTR
Points to a string that contains the name of the color scheme that will be set to the default scheme.
Remarks
An application uses this structure when calling theSystemParametersInfoA function with the SPI_GETHIGHCONTRAST or SPI_SETHIGHCONTRAST value. When using SPI_GETHIGHCONTRAST, an application must specify the cbSize member of the HIGHCONTRAST structure; the SystemParametersInfo function fills the remaining members. An application must specify all structure members when using the SPI_SETHIGHCONTRAST value.
Note
The winuser.h header defines HIGHCONTRAST 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.
