Pad String With Spaces

[cheesestain 0]

I'm trying to compare the length of 2 strings and pad the difference with spaces. Is there a way I can this in a loop

For example, if the difference between string1 and string 2 is 4 characters I want to add 4 spaces to string1.

#include <EditConstants.au3>
#include <GUIConstantsEx.au3>
#include <StaticConstants.au3>
#include <WindowsConstants.au3>

$Replacer = GUICreate("Replacer", 625, 443)
$Label1 = GUICtrlCreateLabel("Old Product Code", 24, 48, 88, 17)
$Label2 = GUICtrlCreateLabel("New Product Code", 20, 74, 94, 17)
$Input1 = GUICtrlCreateInput("", 128, 48, 177, 21)
$Input2 = GUICtrlCreateInput("", 128, 75, 177, 21)
$Label3 = GUICtrlCreateLabel("Result:", 77, 116, 37, 17)
$Button = GUICtrlCreateButton("Run",70, 150,100,20)
GUISetState(@SW_SHOW)

While 1
    $Msg = GUIGetMsg()
    Select
        Case $msg = $Button
            $GetInput1 = GUICtrlRead($Input1)
            $LengthInput1 = StringLen($GetInput1)
            $GetInput2 = GUICtrlRead($Input2)
            $LengthInput2 = StringLen($GetInput2)
            $Difference = $LengthInput1 - $LengthInput2

            $i = 0
            Do
                $i = $i + 1
                $Pad = " "
                $Result = $GetInput2 & $Pad
            Until $i = $Difference
            MsgBox(0,"test","Replaced:" & @CRLF & @CRLF & $GetInput1 & @CRLF & $Result)
        Case $msg = $GUI_EVENT_CLOSE
            ExitLoop

    EndSelect
WEnd

cheesestain,

Welcome to the AutoIt forum.

You can use a loop to do what you want like this:

For $i = 1 To $Difference
    $GetInput2 &= " "
Next
MsgBox(0, "test", "Replaced:" & @CRLF & @CRLF & $GetInput1 & @CRLF & $GetInput2)

You can find out about the &= operator (and other shortcuts like it) in the Help file under <Language Reference - Operators>.

For $i = 1 To $Difference

$GetInput2 &= " "

Next

MsgBox(0, "test", "Replaced:" & @CRLF & @CRLF & $GetInput1 & @CRLF & $GetInput2)

The for loop can even be done easier: _StringRepeat(" ",$Difference) (i imagine the _StringRepeat doing something just like your loop, but why write it yourself?
