with python, I want to get a window title,a stock software window.

the window's title will change when I browse another stock ,now I want to scan it every 100ms and return the new title,but the front text in the window title is the same text.

I can print the title in cmd,but I don't know how to scan it every 100ms and return

I use this code:

from win32gui import *
import re
titles = set() 
titlekey = ''
def foo(hwnd,nouse):
    if IsWindow(hwnd) and IsWindowEnabled(hwnd) and IsWindowVisible(hwnd):
        titles.add(GetWindowText(hwnd))
EnumWindows(foo, 0) 
lt = [t for t in titles if t] 
lt.sort() 
for t in lt:
    if re.match(titlekey,t):
        print t
How to scan every 100ms and return the new title when it change? 
                Where you have code, indent it to format as code, don't put it in a blockquote. Edited for you.

import win32gui
tempWindowName=win32gui.GetWindowText (win32gui.GetForegroundWindow())
import time
while True:
    if (tempWindowName==win32gui.GetWindowText (win32gui.GetForegroundWindow()))
        tempWindowName=win32gui.GetWindowText (win32gui.GetForegroundWindow())
        #do what you want
    time.sleep(0.1)
                em.....I think my idea maybe wrong.I want get the title when it change,return the new title,and use some text in the title to Query data in sqlite,now I think scan it every 100ms maybe can't work.so......I have no idea.....
