Input field listener

[totaln00ber 0]

Hello experts,

Trying to make an input field listener to see if there's any text type. If something is typed inside the input field, then a checkbox that's beside it should automatically be checked off. If the user presses backspace / clears the field, then the checkbox should uncheck itself. Here's what I have so far, but it doesn't seem to be working:

...
$chkCus = GUICtrlCreateCheckbox("", 225, 139, 17, 17)
$txtCus = GUICtrlCreateInput("", 245, 137, 82, 21)

$gCusTxt = GUICtrlRead($txtCus)

While 1
    If $gCusTxt <> "" Then
        GUICtrlSetState($chkCus, $GUI_CHECKED)
    Else
        GUICtrlSetState($chkCus, $GUI_UNCHECKED)
    EndIf
WEnd

#include <GUIConstants.au3>

GUICreate('')

$checkbox = GUICtrlCreateCheckbox('some checkbox', 10, 10)

$input = GUICtrlCreateInput('', 10, 40)

GUISetState()

While 1
    $msg = GUIGetMsg()
    Switch $msg
        Case $GUI_EVENT_CLOSE
            Exit
    EndSwitch
    If GUICtrlRead($input) <> '' Then
        GUICtrlSetState($checkbox, $GUI_CHECKED)
    Else
        GUICtrlSetState($checkbox, $GUI_UNCHECKED)
    EndIf
WEnd

Basically, you needed the guictrlread inside the loop.

Thanks, it works now; not sure what happened there, but I've got the logic down. : )
