Detect new window

[Cusem]

Hey guys,

I'm using a scripts that opens an x amount of windows.

I want the script to halt until the new window is opened and identified by the script.

Right now I'm using the following code:

_OpenNewWindow()

         ;now I want the script to wait until a new window is opened (with a 3 second timeout)
Local $old = WinList("WindowCommonString", "")
Local $new = ""
Local $timer = TimerInit()
Do
     Sleep(50)
     $new = WinList("WindowCommonString", "")
Until $old[0][0] <> $new[0][0] OR TimerDiff($timer) > 3000


         ;detecting timeout
If TimerDiff($timer) > 3000 Then _TimeOutMessage()

         ;now I want to identify the new window
Local $found = 0
Local $NewWindow = ""
For $a = 1 to $new[0][0]
     For $b = 1 to $old[0][0]
          If $new[$a][0] = $old[$b][0] Then $found = $found + 1
     Next
     If $found = 0 Then 
          $NewWindow = $new[$a][0]
          $a = $old[0][0];To exit the For..Next loop
     Endif
Next

This works, but I was wondering if there is an easier way to get the name of the new window.

Looks similar to something I wrote to detect any new processes:

#414954

#443881

Should be easy to modify.
