can't get handle a window

[supperfake]

Hello guys

I have a problem with get handle a window. I have simple code here:

Run("C:\Window\Firefox\firefox.exe")   ;this is location firefox in my computer
$hWnd =WinWait("[CLASS:MozillaWindowClass]", "", 10)   
Sleep(2000)
ControlSend($hWnd,"","","{CTRLDOWN}{SHIFTDOWN}B{CTRLUP}{SHIFTUP}",0)  ;open window Library
Sleep(2000)
$hWnd2 =WinWait("Library", "", 10)
if IsObj($hWnd2) Then MsgBox(0,0,0)

This code can't get handle which have title is Library. So autoit doesn't show MsgBox(0,0,0). I try function Wingethandle but it return same result. 

I can not solve this problem. Do you help me, please?

Perhaps you meant to use IsHWnd instead?
