Is there a on change event?


Recommended Posts

WM_COMMAND message is what you are looking at :

  • For combo, it is the CBN_SELCHANGE notification (with CBS_DROPDOWNLIST)
  • For edit (input), it is the EN_UPDATE or EN_CHANGE notification.

You simply need to register the message thru GUIRegisterMsg and intercept the modifications.  Search forum, as there are tons of examples...

Nine's suggestion of using WM_COMMAND is absolutely the best way of accomplishing your task. However, I know it can be difficult to implement, so I offer an easier, but less effective method. That being said, I think you should use WM_COMMAND instead of my own suggestion.

#include <ButtonConstants.au3>
#include <ComboConstants.au3>
#include <GUIConstantsEx.au3>
#include <StaticConstants.au3>
#include <WindowsConstants.au3>

$Form1 = GUICreate("Form1", 292, 213)
$Combo1 = GUICtrlCreateCombo("", 64, 32, 145, 25)
GUICtrlSetData(-1, "test|test2|test3")
$Label1 = GUICtrlCreateLabel("", 64, 64, 200, 33)
GUICtrlSetFont(-1, 18, 800, 0, "MS Sans Serif")
GUICtrlSetColor(-1, 0x000080)
$Input1 = GUICtrlCreateInput("", 64, 104, 121, 21)
$Label2 = GUICtrlCreateLabel("", 64, 136, 200, 33)
GUICtrlSetFont(-1, 18, 800, 0, "MS Sans Serif")
GUICtrlSetColor(-1, 0x008000)
$Button1 = GUICtrlCreateButton("Exit", 184, 168, 75, 25, $WS_GROUP)
$dummy = GUICtrlCreateDummy()

 Local $aAccelKeys[1][2] = [["{ENTER}", $dummy]] ; when you press ENTER, the combobox & inputbox will update.
While 1
    $nMsg = GUIGetMsg()
    Switch $nMsg
        Case $GUI_EVENT_CLOSE
        Case $Button1
        Case $Combo1
            GUICtrlSetData($Label1, GUICtrlRead($Combo1))
        Case $dummy
            GUICtrlSetData($Label1, GUICtrlRead($Combo1))
            GUICtrlSetData($Label2, GUICtrlRead($Input1))
