Re: GUI checkbox question

Steve,

This is an example of synchonized checkboxes:

#include <GUIConstants.au3>
GUICreate ("")
$n=GUICtrlCreateCheckbox ("N-checkbox",10,10)
GUICtrlSetState (-1,1)
$m=GUICtrlCreateCheckbox ("M-checkbox",10,30)
GUICtrlSetState (-1,1) 
GUISetState ()

; Run the GUI until the dialog is closed
While 1
	$msg = GUIGetMsg()
	
	If $msg = $GUI_EVENT_CLOSE Then 
		ExitLoop
	elseif $msg = $n then
		msgbox (0,"state",StringFormat("GUICtrlRead=%
d\nGUICtrlGetState=%d",GUICtrlRead($n),GUICtrlGetState($n)))
	elseif $msg = $m then
		GUICtrlSetState ($n,GUICtrlRead($m))
	endif
Wend

-1 - meant previous control defined by command GUICtrlCreate....(...)
