Need for transparent overlay advice

[ramjke]

Hi Castorix. I'm looking for the way to display elements on the screen at custom coordinates (like label on the screenshot). Can you please advise the best way to do this? Do I need to create a full screen transparent click-through overlay to place items on?

It depends on which elements need to be displayed
In Win32, "Overlay" windows are usually done with borderless Layered windows (or with DirectComposition for a few years)
(for just a message, "Tracking Tooltips" could be used too (with NULL or GetDesktopWindow() as parent))
