This thread has been very valuable for me and has provided
clarifications which I could not get after hours of surfing web
/reading python on win32 / python developer handbook and so on.

Here are more questions that I am encountering
a) the code above will return a click event from an anchor element.
However, I need to identify which anchor element was clicked on.
Similarly, if a user clicks on one cell in HTML table - I need to
determine its identity.
One possible solution to this will be to look at the onClick event
provided by HTML_DocumentEvents and as desribed in msdn library
http://msdn.microsoft.com/library/default.asp?url=/workshop/browser/mshtml/reference/events/events.asp

The problem is that msdn documentation says that in order to identify
the element that was clicked - one has to query on IHTMLWindow2::event
property on iHTMLWindow2 interface to get IEventOBj interface and then
from there - use query interfce to get to the id of the element.

How do I do this in python? ie. I have this code
class Doc_Events(doc_mod.HTMLDocumentEvents):
    def Ononclick(self):
        print 'onClick fired '
and I see onClick being trapped.
Now I need to go and get a reference to the iHTMLWindow2 interface. For
this I need to get a reference to doc_mod (as far as I can see). How do
I get that in the OnonClick method above.

b) You had mentioned PumpWaitingMessages in the previous posting. I
first encountered this on newsgroup postings. None of the standard
books (python on win32 / python developer) seem to explain this in
detail although this seems to be commonly used. Though I understand
this now - my problem is that there seems to be a lack of cohesive
explanation on how python ties up with COM (despite a good chapter 12
on python win32 book). How does a newbie get more info on coding?
Essentially (a) is also a generic question which can be included in a
standard text. If nothing of this sort exists - maybe I will think of
jotting down the notes and posting on a public website.
