    <p>Chrome supports the Windows accessibility APIs, so you can use those to extract information both from the chrome - including the broswer bar - and also from web pages. Think of this API as a more abstract version of enumerating window controls.</p> <p>Check out the <a href="http://msdn.microsoft.com/en-us/library/windows/desktop/dd318521(v=vs.85).aspx" rel="nofollow noreferrer">Inspect Objects</a> tool to explore what information you can get access to - it does look as though the address bar and contents are available.</p> <p>You can get the same information in C# using the <a href="http://msdn.microsoft.com/en-us/library/system.windows.automation.automationelement.aspx" rel="nofollow noreferrer">AutomationElement</a> set of classes:</p> <ul> <li>use AutomationElement windowEl = <a href="http://msdn.microsoft.com/en-us/library/system.windows.automation.automationelement.fromhandle.aspx" rel="nofollow noreferrer">AutomationElement.FromHandle(new IntPtr(hwnd))</a>; as a starting point if you know the HWND of the tree</li> <li>then try AutomationElement editEl = <a href="http://msdn.microsoft.com/en-us/library/system.windows.automation.automationelement.findfirst.aspx" rel="nofollow noreferrer">AutomationElement.FindFirst</a>(TreeScope.Descendants, new PropertyCondition(AutomationElement.ControlTypeProperty, <a href="http://msdn.microsoft.com/en-us/library/system.windows.automation.controltype.edit.aspx" rel="nofollow noreferrer">ControlType.Edit</a>)) to find the first element that has ControlType of Edit.
