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.
