Here we go...

;
If OpenWindow(0,100,150,450,200,#PB_Window_SystemMenu,"Test")
  CreateGadgetList(WindowID())
  sg=StringGadget(1,20,20,100,21,"",#PB_String_Multiline|#ES_AUTOVSCROLL)
  ActivateGadget(1)
  Repeat
    ev=WaitWindowEvent()
    If ev=#PB_EventGadget
      a$=GetGadgetText(1) : pos=FindString(a$,Chr(13)+Chr(10),1)
      If pos0 ; Was Enter pressed on the StringGadget?
        SetGadgetText(1,ReplaceString(a$,Chr(13)+Chr(10),"")) ; Yes, so remove CR+LF.
        SendMessage_(GadgetID(1), #EM_SETSEL, pos, pos)  ; Set cursor Position

I tried to use this approach in my code and it didn't work. I had a plain StringGadget with no flags so I added them in accordance with the sample above and it worked.

#PB_String_Multiline|#ES_AUTOVSCROLL

Makes sense but wasn't obvious to me at first, just in case anyone else stumbles on this one.

Yes, #PB_String_Multiline|#ES_AUTOVSCROLL is what stops the ding sound,
otherwise Windows thinks the gadget is a single line and won't allow Enter to
be pressed on it (which gives the sound).
I compile using 5.31 (x86) on Win 7 Ultimate (64-bit).
