WinRT keep display on

Hi David,

I'm trying to keep the screen programmatically on for some time, but I'm not
doing it right. This is my simple code:

--------------------------

    using namespace Windows::System::Display;

    DisplayRequest ^ request = ref new DisplayRequest();

    if (keepOn != 0)
    {
        request->RequestActive();
    }
    else
    {
        request->RequestRelease();
    }

---------------------------

but there must be sth. fundamentally wrong with it, because when I call 
RequestRelease() I get an exception from WinRT about calling something at an
unexpected time. I'm calling it from SDL's main thread, which is probably 
not the UI thread.

I saw in your code for the game bar that you are using something called a 
"dispatcher", I suppose this is to run sth. on the UI thread. Do I need to 
do the same for DisplayRequest()? Anything else I have missed?


Regards,

Daniel
