IWebBrowser2 OnBeforeNavigate Event - EventHandler

Question

I was reading about the IWebBrowser2-interface and the BeforeNavigate-Event and the OnBeforeNavigate Handler. I was wondering about the following description:

This member function is called by the framework to cause an event to fire before a navigation occurs in the web browser.

The quote can be found here: http://msdn.microsoft.com/de-de/library/2chzz53b.aspx

My understanding was the follwing: an event gets fired and causes a method to be executed, but in the upper description it is completely the other way round.

Can anybody please clarify the situation for me?

Answer 1

The wording is awkward because the CHtmlView is simply a thin wrapper around a COM object. It works like this:

1. Internet Explorer COM object fires a event on the DWebBrowserEvents2 interface
2. ATL's event sink responds to this call by calling any registered handler methods for the CHtmlView::BeforeNavigate event.
