There is the solution!

**Can maximize a window
DECLARE INTEGER ShowWindow ;
IN WIN32API ;
	INTEGER  hWnd , ;
	INTEGER nState

**get the window handle
DECLARE INTEGER FindWindow ;
IN WIN32API ;
	STRING cNull, ;
	STRING cWinName 

**place the window on top
DECLARE INTEGER BringWindowToTop ;
IN WIN32API ;
	INTEGER  hWnd 

*Sample code, it this case the window title = 'Calculatrice'
IF !FindWindow( 0, 'Calculatrice') > 0
	*Not find, do something...
ELSE
	*Find! Bring it to top and maximize it!
	=BringWindowToTop(FindWindow( 0, 'Calculatrice'))
	=ShowWindow(FindWindow( 0, 'Calculatrice'),1)
