Why cannot BHO receive the DocumentComplete(DISPID_DOCUMENTCOMPLETE) event again when I refresh

I have written a bho object and sinked the events of IE.

when navigate to a new page,bho can receive the documentcomplete event.

but when I refresh the current page, bho cannot receive the event again,while bho can receive other event well. (I am sure then I havenot Unadvised the events)

who could tell me why?

How are you hooking to the event. When a page refresh happens you will need to rehook the event as the page will have been entirely destroyed and recreated.

Unfortunately IE doesnt fire BeforeNavigate2 and DocumentComplete2 when the page refresh is clicked. There are several work arounds I found on the web (which are mainly guess works), but you may find this one close to what you might want to do http://www.codeproject.com/internet/detecting_the_ie_refresh.asp

What works for me:

My BHO implements (among many other things) IDispatch and IOleObjectWithSite

In IOleObjectWithSite::SetSite, query for the connection point container, find the connection point for DIID_DWebBrowserEvents2, and advise with your BHO as reinterpret_cast<IDispatch*>

In your BHO, override the implementation of Invoke(). It gets called with DISPID_DOCUMENTCOMPLETE on a refresh.

Hope this helps,
