The object on the page implements an IHTMLElement interface,
also IEConnector (use QueryInterface and succeeded in any case),
but the connection point container owns no connection
point that names _IEConnectorEvent.

Query the object for IHTMLObjectElement, call get_object. That will give
you another interface pointer. Now query this new pointer for
IConnectionPointContainer and see if you can sink events from it.

The object that implements IHTMLElement is the browser-provided object
that represents <object> tag in DOM. It has its own events, like
onclick. Its 'object' property returns the interface pointer of the
actual ActiveX control it hosts. That's the one you want to sink events
from.

With sufficient thrust, pigs fly just fine. However, this is not
necessarily a good idea. It is hard to be sure where they are going to
land, and it could be dangerous sitting under them as they fly
overhead. -- RFC 1925
