Each Movie Player instance is associated with a playback window called a stage window. The stage window can be any pop-up or overlapped window. You can use the following functions to manage the stage window:
mmpSetStage
Sets the stage window for a Movie Player instance and specifies the position of the playback area.
mmpGetStage
Gets the current stage information for a Movie Player instance.
mmpSetDC
Provides the Movie Player a handle to a device context.
mmpUpdate
Performs a screen update in the invalid rectangle.
mmpGetPaletteHandle
Returns a handle to the movie palette.
To correctly manage the movie palette, handle wait-for-mouse tempo commands, and process MCI script-channel commands, the Movie Player subclasses the stage window and handles the following messages:
