WinGetState, none of the states are declared.

[InunoTaishou]

From the help file for WinGetState:

Success: a value indicating the state of the window. Multiple values are added together so use BitAND() to examine the part you are interested in:
$WIN_STATE_EXISTS (1) = Window exists
$WIN_STATE_VISIBLE (2) = Window is visible
$WIN_STATE_ENABLED (4) = Window is enabled
$WIN_STATE_ACTIVE (8) = Window is active
$WIN_STATE_MINIMIZED (16) = Window is minimized
$WIN_STATE_MAXIMIZED (32) = Window is maximized 
Failure: 0 and sets the @error flag to non-zero if the window is not found. 

Constants are defined in "AutoItConstants.au3".

None of the these variables are declared in any of the files in the include folder.
