Switch to web dialog box in selenium webdriver: Python

Question

I want to handle a web dialog box under selenium web driver (Internet Explorer) . I am using Python

In my application when I click on Icon, a web dialog box opens which contains some text boxes (Webelements) and I need to click on save button after entering some text. The problem is I dont know whether the focus got switched to the web dialog box or not. Here is my code

driver.find_element_by_xpath("//img[contains(@src,'/images/btn_add.gif')]").click()
driver.switch_to_alert()
driver.find_element_by_name("report_cutoff_date").sendkeys("10/31/2010")

Here is the error I am getting

Traceback (most recent call last):
File "C:\Users\vthaduri\workspace\LDC\test.py", line 14, in <module>

selenium.common.exceptions.NoSuchElementException: Message: u'Unable to find element with name == report_cutoff_date' 

For your information the webelement is present with same name and cutoff date.

Can some one help me on this.

Try this:

parent_h = browser.current_window_handle
# click on the link that opens a new window
handles = browser.window_handles # before the pop-up window closes
handles.remove(parent_h)
browser.switch_to_window(handles.pop())
# do stuff in the popup
# popup window closes
browser.switch_to_window(parent_h)
# and you're back
