Working with Barcodes!

Hi guys! How are you? Hope fine :) I'm working with a barcode reader and I'd like to have the same result on my input in a GUI as I have on an Excel sheet.
Better example:
If I scan the barcode, on the Excel sheet I have a totally different result on a GUI's input. Why? :) Thanks :D 

EDIT: My mistake... The barcode reads and print correctly data, but, the interconnection with EN_CHANGE command, print only 1 character... How can I still use that function, without printing only 1 character? Thanks :)

I create the GUI with:
 

Func GUIPrelevaProdotto()
    #Region ### START Koda GUI section ### Form=C:\Users\Portatile-60\Documents\Documenti Lavoro\AutoIt\Gestione Magazzino\form_PrelevaProdotto.kxf
    $form_PrelevaProdotto = GUICreate("form_PrelevaProdotto", 334, 108, @DesktopWidth/2 - 96, @DesktopHeight/2 - 161) ; 192, 124
    $input_CodiceProdotto = GUICtrlCreateInput("input_CodiceProdotto", 16, 48, 305, 21)
    $input_Messaggio = GUICtrlCreateInput("input_CodiceProdotto", 16, 72, 305, 21)
    $label_Titolo = GUICtrlCreateLabel("Preleva Prodotto", 68, 10, 196, 33)
    GUICtrlSetFont(-1, 18, 800, 0, "Arial")
    GUISetState(@SW_SHOW, $form_PrelevaProdotto)
    #EndRegion ### END Koda GUI section ###
EndFunc

I manage my WM_COMMAND with:
 

Func My_WM_COMMAND($hwnd, $msg, $wparam, $lparam)
    If _WinAPI_LoWord($wparam) = $input_CodiceProdotto And _WinAPI_HiWord($wparam) = $EN_KILLFOCUS And GUICtrlRead($input_CodiceProdotto) <> "" Then
        ; Do the research
        PrelevaProdotto()
        GUICtrlSetState($input_CodiceProdotto, $GUI_FOCUS)
    EndIf
    Return $GUI_RUNDEFMSG
EndFunc

The func PrelevaProdotto manages the research of the barcode scanned...
It doesn't affect the code that you need :)

I'd like to scan the barcode, and, without touch anything, call the function PrelevaProdotto(), but, as I explained above, I didn't manage to do it with the event $EN_CHANGE, because seems to be too much faster ( it doesn't allow the text to be entered in the input from the barcode scanner ), it only receive 1 character, it's too much fast! Thanks for your reply :)

Drag, I thought the update notification would fire when the update was completed, versus the change notification which fires when a change to text is made (which is probably why you got 1 letter at a time).  

 

What is going on in your PrelevaProdotto function?  How does it read the inputbox?

I added this at the function WM_COMMAND, and works :D 
 

If _WinAPI_LoWord($wparam) = $input_CodiceProdotto And _WinAPI_HiWord($wparam) = $EN_UPDATE And Sleep(250) And GUICtrlRead($input_CodiceProdotto) <> "" Then

Thanks for your help! Stay tuned, please! I need your knowledge! Really thanks! :D
