You can use the GetWindowText API call. Pass it (1) your window handle, 
(2) a string buffer into which the text is to be copied, and (3) the 
maximum number of characters to copy to the buffer:

require 'Win32API'

getForegroundWindow = Win32API.new('user32', 'GetForegroundWindow', [], 
'L')
getWindowText = Win32API.new('user32', 'GetWindowText', ['L', 'P', 'I'], 
'I')

window_handle = getForegroundWindow.Call()
title_buffer = ' ' * 256
getWindowText.Call(window_handle, title_buffer, 256)
puts(title_buffer)
