In this project, we use the red dot(Debug Cursor) to point the position we want to touch, so we can touch the right position on the screen or window,

but we can't show it over the pop-up menu, windows task bar, full screen windows(like Windows Media Center),
and Windows login Screen(especially this one, I reaaaaaaaaalllly need this function to key-in my password ......)

 

I am just thinking about is there any possibility to use the low level video card dirver API (like OSD,On Screen Display) to show this "Red dot" ,
or windows kernel provide API to do it like as mouse cursor showing over all windows form....

does anyone have the idea to conquer this problem?
