Context After playing with AutoIt for some time I'm trying to get a window topmost. I'd like to get the same effect as AutoIt v3 Window Info with the flag Always On Top set. The window can be put on top of all other windows with a button. GUI I have this window with 2 buttons on it. The first button Set window topmost will change the style of the window to make it topmost. The second button Set window normal will reset the style of the window. By default he window is not topmost. Source code
