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.
