how to get title of window using handle

Hi,
Here is my code

Opt("WinTitleMatchMode", 2)
Local $TextFileName = "Log-of-audacity-window.txt"
If WinExists("Cross-Platform") Then
$Logging = "Audacity« Cross-Cross-Platform Sound Editor window found" &@CRLF
FileWrite($TextFileName, $Logging)
Local $Cross-Platform_window_handle = WinGetHandle("Cross-Platform")
$Logging = "Window handle is " &$Cross-Platform_window_handle &@CRLF
FileWrite($TextFileName, $Logging)
Local $found_win_title = ??
$Logging = "Window title is " &$found_win_title&@CRLF
FileWrite($TextFileName, $Logging)
EndIf
[code]

Here I am searching a window using a substring of title .
Now I want to know the full title of window that was found .
How can I do that ?

Thanks.
