There is a game that is running in windowed mode on the whole screen, on top of it you can display some information, as some programs do. I would like to create a similar area and transparent and so that the mouse clicks did not stop at this window but pass through the game, in other words, stretch the shape to the full width and make it topmost not roll, because it will be impossible to click on the game mouse. Tell me how to implement such a window?

    In Windows Forms 2.0, there is a new property called ShowWithoutActivation - ShowWindowPos with the SWP_NOACTIVATE flag or the ShowWindow with the SW_SHOWNA flag.
