Hi! I want to know whether it's possible to get Information about opened pages in chrome (page title, url) from third party app (not extensions)?
It's definitely possible using Fiddler. In the Web Sessions list, it shows all the URLs that are accessed, and the program (and PID) that accessed them, including Chrome. If you click on one of the URLs and look under Inspectors on the right, then Text View on the lower section, you can see the <title>
section for each page.
Fiddler is tampering traffic, it is not what i really want. i can get this info from any opened browser just using their gui except chrome... I can't even read chrome session.
You can try use the Accessibility techniques. Chrome implemented IAccessible interfaces in Chromium that any screen readers can read. If you implement a screen reader like application you can easily get those data. But to do that, you would need to understand how accessible applications work.
Or you can check out ManagedSpy, where the source code is provided: http://msdn.microsoft.com/en-us/magazine/cc163617.aspx
