Sub windows problem

[Killer]

I am trying to open a sub window from a window. Instead of the usual msgbox I want one where I can have my own buttons. I create a sub window but having problem closing it. Can someone help me on the code?

#include <GUIConstants.au3>

GUICreate("My GUI edit")

$Button_2a=""

$Button_1 = GUICtrlCreateButton ("Run Notepad", 10, 30, 100)

$Button_2 = GUICtrlCreateButton ( "Button Test", 10, 120)

$myedit=GUICtrlCreateEdit ($Button_1& @CRLF, 176,32,121,97,$ES_AUTOVSCROLL+$WS_VSCROLL)

GUISetState ()

; will be append dont' forget 3rd parameter

GUICtrlSetData ($myedit, "Second line",1)

; Run the GUI until the dialog is closed

While 1

$msg = GUIGetMsg()

if $msg = $Button_1 then

GUICreate("2ndwind",150,150)

$Button_1a = GUICtrlCreateButton ("Run", 10, 30, 100)

$Button_2a = GUICtrlCreateButton ( "close", 10, 120)

GUISetState ()

endif

If $msg = $Button_2a and WinActive("2ndwind")=1 Then

GUIDelete("2ndwind")

msgbox(0,"","closeing")

endif

If $msg = $GUI_EVENT_CLOSE and WinActive("2ndwind")<>1 Then

exitloop

endif

Wend
