Character limit in an input box

[Joboy2k]

Hey guys. This question has already been asked before but as it was like a year ago I wondered if there still was no better way of doing it other than

http://www.autoitscript.com/forum/index.php?showtopic=102964&st=0&p=730024&hl=Limit%20characters%20in%20an%20input&fromsearch=1&#entry730024

What I'm aiming to do is create a GUI that takes down credit card details from our customer that call up on the phone.

I want to have 4 boxes for the long number on the card.

I want each box to have a limit of 4 characters and I want it to automatically move the attention to the next input box. Is there a way of doing this better then how the link solves it?

Thanks in advance

You mean like GUICtrlSetLimit ?

yes that answers my limiting question thank you, but i need something that will send out a signal when it hits the limit so i can change the focus to the next input box. any ideas?

I tried this, but i'ts not working as is supposed to.

#include <GUIConstants.au3>

Global $LimiReached = False

$GUI = GUICreate("", 500, 500)
$Input1 = GUICtrlCreateInput("", 10, 10, 150, 20)
$Input2 = GUICtrlCreateInput("", 10, 35, 150, 20)

GUICtrlSetLimit($Input1, 10, 0)

GUISetState()
While Sleep(10)
    Switch GUIGetMsg()
        Case -3
            Exit
    EndSwitch

    If (StringLen(GUICtrlRead($Input1)) = 10 & $LimiReached = False) Then
        GUICtrlSetState($Input2, $GUI_FOCUS)
        $LimiReached = True
    EndIf

    ConsoleWrite("Length input1: " & StringLen(GUICtrlRead($Input1)) & @CRLF & "Limit reached: " & $LimiReached & @CRLF) ; Weird enough, $LimiReached is set to True without input1 having 10 characters... Weird.
WEnd
