How to detect the "enter" sent from a bar code scanner - (Moved)

[Yodavish]

I'm completely new to AutoIt. I have a script that was given to me and I'm trying to update it. The issue I'm trying to resolve is when a barcode is accidentally scanned while a pdf viewer is active it will send an alert, in my case, just do a msgbox but eventually play a sound.  I can't get the detection of the enter produced by the scanner but it does work when I hit the enter key. Any help on this would be greatly appreciated. Here is the main portion of the code below:
 

Local $hDLL = DllOpen("user32.dll")

While 1 

    If WinActive("PDFViewer") AND _IsPressed("0D", $hDLL) Then
        MsgBox(0, "Test", "Enter was pressed with SumatraPDF open")
    EndIf

WEnd

Moved to the appropriate forum, as the Developer General Discussion forum very clearly states:

Maybe my example from my Barcode UDF can help you.

I use WM_COMMAND + EN_CHANGE

@Zedna I'm still new to AutoIt. What command is used to detect a randomly scanned barcode that a GUI isn't prompted for? In AutoHotKey it can detect the "Enter::" produced from the scanned barcode but it doesn't work the same in AutoIt.
