Working with iTunes WebViewWindowClass

Hi friends,

I'm new to iTunes and I'm working on script to download free ipa to windows machine. Is there any way to get the handle to an  IE form elements displayed on a iTunes in the WebViewWindowClass control?

I have searched the whole forum but I couldn't find any post related to downloading on iTunes.

My script executes the following cmd to goto the downloading page:
C:\Program Files (x86)\Internet Explorer>iexplore itmss://itunes.apple.com/us/app/ibooks/id364709193?mt=8

and after loading iTunes I want to click on the [Free] button displayed on the Itunes.

Please help.
