Input - listen event onChange

[talisin]

Hey there,

ive a problem with an input field.

If the user write something in the Input1 Field, the second one should be disabled.

The following code works fine but only if the user change the focus of the inputfield.

So is there any way how i could check if someone write into the field?

#include <GUIConstants.au3>
#Region ### START Koda GUI section ### Form=
$Form1 = GUICreate("Form1", 371, 161, 242, 218)
$Input1 = GUICtrlCreateInput("", 40, 48, 273, 21)
$Input2 = GUICtrlCreateInput("", 40, 88, 121, 21)
$Input3 = GUICtrlCreateInput("", 192, 88, 121, 21)
GUISetState(@SW_SHOW)
#EndRegion ### END Koda GUI section ###

While 1
    $nMsg = GUIGetMsg()
    Switch $nMsg
        Case $GUI_EVENT_CLOSE
            Exit

        Case $Input1
            If Guictrlread($Input1) <> "" Then
                GUICtrlSetState($Input2, $GUI_DISABLE)
            Else
                GUICtrlSetState($Input2, $GUI_ENABLE)
            EndIf
    EndSwitch
WEnd
