the class chrome_omniboxView is no longer available?
I've just written a Chrome extension to resolve this exact problem. I've put it in the chrome webstore (free) here: https://chrome.google.com/webstore/detail/add-url-to-page-title/ghpeimfjbonkimelnkbgekmcboomkgmi
All it does is to convert the html title of the page to this format:Original Title |url:[http://www.the-url.com]
This is put into the window title by Chrome, which you can read using NativeWIN32.GetWindowText(handle);
Run Spy++ to figure out the proper class names and window handles you need. You should have it installed assuming you have Visual Studio installed.
With it, you can point at the window, see the hierarchy of window handles, and the exact class name you should use with FindWindow()/GetWindow() API calls.
