Exactly one of the following flags specifying how to show the window:
SW_HIDE = 0
Hide the window.
SW_MAXIMIZE = 3
Maximize the window.
SW_MINIMIZE = 6
Minimize the window.
SW_RESTORE = 9
Restore the window (not maximized nor minimized).
SW_SHOW = 5
Show the window.
SW_SHOWMAXIMIZED = 3
Show the window maximized.
SW_SHOWMINIMIZED = 2
Show the window minimized.
SW_SHOWMINNOACTIVE = 7
Show the window minimized but do not activate it.
SW_SHOWNA = 8
Show the window in its current state but do not activate it.
