Thanks for your prompt responses and the code.
However, when I run the code I get com error
d=win32com.client.DispatchWithEvents(ie.Document, Doc_Events)
File "C:\Python23\lib\site-packages\win32com\client\__init__.py",
line 199, in __getattr__
return getattr(self._obj_, attr)
File "C:\Python23\lib\site-packages\win32com\client\__init__.py",
line 455, in __getattr__
return self._ApplyTypes_(*args)
File "C:\Python23\lib\site-packages\win32com\client\__init__.py",
line 446, in _ApplyTypes_
return self._get_good_object_(
com_error: (-2147352567, 'Exception occurred.', (0, None, None, None,
0, -2147467259), None)
I am a newbie to python(started coding a few months ago).
This appears to be a fairly common error when COM objects are not
hooked up properly. Though I have not been able to find a solution or
the reason for this.
Thanks again for the explanation.All the information that I had
acquired now seems to fall into place. I was not aware about
doc_mod.HTMLAnchorEvents. Where can I find more documentation about
this?
