The SetBkColor function sets the current background color to the specified color value, or to the nearest physical color if the device cannot represent the specified color value.
COLORREF SetBkColor( HDC hdc, COLORREF color );
A handle to the device context.
If the function succeeds, the return value specifies the previous background color as a COLORREF value.
If the function fails, the return value is CLR_INVALID.
This function fills the gaps between styled lines drawn using a pen created by the CreatePen function; it does not fill the gaps between styled lines drawn using a pen created by the ExtCreatePen function. The SetBkColor function also sets the background colors for TextOut and ExtTextOut.
If the background mode is OPAQUE, the background color is used to fill gaps between styled lines, gaps between hatched lines in brushes, and character cells. The background color is also used when converting bitmaps from color to monochrome and vice versa.
