HIGHCONTRAST info  Overview  Group

The HIGHCONTRAST structure contains information about the High Contrast Mode accessibility feature, which 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.

typedef struct tagHIGHCONTRAST {     // hc 

    UINT             cbSize; 

    DWORD            dwFlags; 

    LPTSTR           lpszDefaultScheme; 

} HIGHCONTRAST, FAR* LPHIGHCONTRAST;

Remarks

An application uses this structure when calling the SystemParametersInfo 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.
