Fires when a navigation operation finishes, is halted, or fails.
No return value.
The DISPID for this event is defined in exdispid.h. Use this value to identify the event handler when implementing IDispatch::Invoke.
Unlike DWebBrowserEvents::NavigateComplete or DWebBrowserEvents2::NavigateComplete2, which are fired only when a URL is successfully navigated to, this event is always fired after a navigation starts. Any animation or "busy" indication that the container must display should be connected to this event.
Each DWebBrowserEvents2::DownloadBegin event has a corresponding DWebBrowserEvents2::DownloadComplete event.
