how to close a gui but not the program?

[tsue]

hello recently i had to make a program that runs a configuration gui but once it is open i cant figure out how to close it without closing the program

here is the code

while 1
guitoclose()
func guitoclose()
While 1
$nMsg = GUIGetMsg()
Switch $nMsg
  Case $GUI_EVENT_CLOSE
   Exit ; i thin i need to change this but cant find another thing to change it
case X
case Y
endswitch
wend
endfunc
wend
