Seamless, Proper Loading Screens! [Play Movies, Audio & Animated Widgets!]

Got an error ( GetMoviePlayer() not found ) . Compiling with VS2015.

Do I need to include something for the cpp?

Edit: Ah I had to include #include “MediaPlayer.h” in the cpp.

So Im a bit new to c++ … I made some functions in c++ but I still not know how to play with this system a Movie or Widget.
