Also I want to know how can I simply draw anything in this control

void CBrowserView::OnDocumentComplete(LPCTSTR lpszURL)
{
    MSHTML::IHTMLPainterPtr pPaint = GetHtmlDocument();
}

here CBrowserView is derived from CHtmlView.
I am facing problems regarding the arguments that must be passed to

MSHTML::IHMLPainterPtr::Draw(RECT rcBounds,
    RECT rcUpdate,
    LONG lDrawFlags,
    HDC hdc,
    LPVOID pvDrawObject
);

especially pvDrawObject.

and I am getting the following errors:

conversion requires

Replace

COM_INTERFACE_ENTRY2(HTMLElementEvents,IEventSink)

with

COM_INTERFACE_ENTRY(IEventSink)

I don't know what the author was thinking when he wrote that first
line - it makes no sense whatsoever. With this change, the project
compiles. I haven't actually run it though.

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
