Is there any way to set fullscreen with WIN API like in SDL??

According to MSDN, you can create a window that is automatically maximized by passing WS_MAXIMIZE as the dwstyle in the CreateWindow() function.

See, now I don't even program in Win32, I did for maybe a month two years ago but just looking through MSDN for 5 minutes helps you find the answer.

Win32 CreateWindow() function
Window styles

In a lib I wrote, a GDI only graphics lib, to get a fullscreen window I can write unto like a fullscreen surface, I used these:

- Like someone mentionned, you use ChangeDisplaySettings to set the mode you want ( and don't forget to always call it with NULL values when exiting your program, or the user is stuck in the resolution you set )

- You create a window with no borders, no title, no buttons, no nothing, say it to be always on top ( otherwise, stuff might pop over it ) and with the exact size of the screen and position 0,0. That should work.

- You should handle minimizing and some stuff yourself then, otherwise the user is stuck in your app until it closes it for good.

Hope it helps.
