macro controls how an MCI window realized in the foreground or background.
This macro also causes the palette for the MCI window to be realized in the
process. You can use this macro or explicitly send the MCIWNDM_REALIZE
Handle of the MCIWnd window.
Background flag. Specify TRUE for this parameter for the window to be realized
in the background or FALSE if the window can be realized in the foreground.
Returns zero if successful or an error otherwise.
A common use for MCIWndRealize
is to coordinate palette ownership between an MCI control and the application
that contains it. The application can have the MCI window realize in the
background and realize its own palette in the foreground.
If your application contains an MCI control, but does not need to realize its
palette, you can use this macro to handle the WM_PALETTECHANGED and
WM_QUERYNEWPALETTE messages, instead of using RealizePalette
. However, it is usually easier to call the SendMessage
function to forward the message to the MCIWnd window, which will
automatically realize the palette.
