The function returns (1) if the current (foreground) application runs in full screen mode (not maximized), otherwise - (0). Check for F.E.A.R. 2, S.T.A.L.K.E.R. Clear Sky and Crysis at different resolutions. Works fine.


Func _IsFullScreen()

    Local $hWnd = DllCall('user32.dll', 'hwnd', 'GetForegroundWindow')

    $hWnd = $hWnd[0]

    If (@error) Or ($hWnd = 0) Then
        Return SetError(1, 0, -1)

    If (StringInStr(WinGetClassList($hWnd), 'SHELLDLL_DefView') = 0) And (BitAND(WinGetState($hWnd), 2) = 2) And (_WinAPI_GetClientWidth($hWnd) = @DesktopWidth) And (_WinAPI_GetClientHeight($hWnd) = @DesktopHeight) Then
        Return 1
    Return 0
EndFunc   ;==>_IsFullScreen
