Represents the host window of a WebBrowser control.

If you are familiar with OLE development using the unmanaged WebBrowser ActiveX control, you can extend the functionality of the Windows Forms WebBrowser control, which is a managed wrapper for the ActiveX control. You can use this extensibility, for example, to customize the browser shortcut menu and shortcut keys or to provide a custom security configuration for hosted documents.
To use this feature, implement classes that inherit from the WebBrowser and classes. The unmanaged WebBrowser ActiveX control uses the protected WebBrowser.CreateWebBrowserSiteBase method to retrieve extensibility interfaces implemented by the class. Override the CreateWebBrowserSiteBase method to return an instance of your own class that inherits from the class. The class provides a default implementations of the OLE IDocHostUIHandler interface. For more information, see IDocHostUIHandler Interface in the MSDN library. You can provide your own implementation of this interface or implement any other WebBrowser ActiveX control interface in order to customize the behavior of the control. For more information, see WebBrowser Control in the MSDN library.
If you provide your own implementation for any IDocHostUIHandler members, you must implement all the members of that interface.
