Using GUICtrlRead with &

[ni3dprint]

I'm sure this is something stupid, but why won't this work?

[autoit]

Local $iNumber1 = GUICtrlCreateInput("", 50 , 80 , 40, 30, $ES_NUMBER)
GUICtrlSetLimit(-1, 4)
Local $iNumber2 = GUICtrlCreateInput("", 50 , 130 , 40, 30, $ES_NUMBER)
GUICtrlSetLimit(-1, 4)

[/autoit]

etc..

Local $n=1

then in the funtion:

[autoit]

local $sCounterID=("$iNumber" & $n)
   $iCounter=GUICtrlRead($sCounterID)
ConsoleWrite($sCounterID)
ConsoleWrite($iCounter)

[/autoit]

 

the idea is to iterate the $n to read the various inputs ( I have 15 of them), however the GUICtrlRead simply returns 0?  I know it's working $sCounterID is displaying correctly and if I replace it with $iNumber1 etc then the script returns the input value correctly.

strange one?

Thanks for any help!

ni3dprint,

Concatenating the variable name as you are doing results in a literal  string - when that string is passed to GUICtrlRead it is interpreted as a number, as that is what the function expects. And a literal string which does not start with a numeric character is interpreted as 0 - hence the function fails to read the correct control.

What you need to do is to use Eval like this:

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

$hGUI = GUICreate("Test", 500, 500)

Local $iNumber1 = GUICtrlCreateInput("34", 50, 80, 40, 30, $ES_NUMBER)

$cButton = GUICtrlCreateButton("Test", 10, 300, 80, 30)

GUISetState()

While 1

    Switch GUIGetMsg()
        Case $GUI_EVENT_CLOSE
            Exit
        Case $cButton
            _Test()
    EndSwitch

WEnd

Func _Test()

    Local $n = 1
    Local $sCounterID = ("iNumber" & $n)
    $iCounter = GUICtrlRead(Eval($sCounterID))
    ConsoleWrite($sCounterID & @CRLF)
    ConsoleWrite($iCounter & @CRLF)

EndFunc   ;==>_Test

But even better would be to use an array to hold the ControlIDs of your inputs - then you can use a simple loop to iterate through them.
