Input box: Select a substring?

[lavascript]

I'm creating a small MsgBox-style GUI window for a login, and I'm giving my $Username input box the default text "DOMAIN\Username". When I run it, the default text is highlighted as expected, but it'd be nicer if I could highlight only the username portion. I realize I could use multiple input fields, but I'd rather not.

I'm currently accomplishing this by:

GUISetState(@SW_SHOW)
Send("{END}+{LEFT 8}")

and that technically works, but I was wondering if there was a "right" way to do this.

Is the domain name going to be static? If so, I would just put it in a label:

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

Local $msg
GUICreate("Login", 400, 100)
GUICtrlCreateLabel("DOMAIN\", 10, 23, 50, 50)
GUICtrlCreateInput("", 60, 20, 150, 20)
GUISetState(@SW_SHOW)

While 1
    $msg = GUIGetMsg()
  Select
   Case $msg = $GUI_EVENT_CLOSE
    ExitLoop
  EndSelect
WEnd

GUIDelete()

Yeah, I know. Probably 90% of the time, but not necessarily.

Or do a drop-down to let them select the domain.

Just to show the direction..

#include <GuiEdit.au3>
GUICreate("Login", 300, 200)
GUICtrlCreateLabel("Domain", 10, 10, 80, 20, 0x200)
$nEditDomain = GUICtrlCreateInput("DOMAIN\Username", 100, 10, 180, 20)
GUICtrlCreateLabel("Password", 10, 50, 80, 20, 0x200)
GUICtrlCreateInput("", 100, 50, 180, 20)

GUISetState()

_GUICtrlEdit_SetSel($nEditDomain, 7, 1000)
Do
Until GUIGetMsg() = -3

lavascript,

The code above -3 is $GUI_EVENT_CLOSE in case you were wondering.
