How to hide the window on the projector?

Hi all programmers!

Very much in need of your help.
Tell me how to make a window invisible to the projector?
I got to do the following:

Opt("GUIOnEventMode", 1)
$Form = GUICreate("Control Panel", 300, 200, -1, -1)
$Button1 = GUICtrlCreateButton("Start",10,10,60,20)
GUICtrlSetOnEvent(-1,"Start")
$Button2 = GUICtrlCreateButton("Exit",80,10,60,20)
GUICtrlSetOnEvent(-1,"Quit")GUISetState(@SW_SHOW)
Sleep(3000)GUISetStyle(0x94000003)
While 1
Sleep(1000)
WEndFunc Start()
MsgBox(0,0,"Starting!")
EndFunc
Func Quit()
Exit
EndFunc

But in this case, is not functioning and highly variable interface! (

I will be very grateful for any tips and help - really need to solve this problem! And I think it is solvable times can hide tooltips and windows.
