question about python COM programming

Question

Hey,

I am trying to get the Dispatch object of IHTMLDocument3, so I wrote the following code

wo = pythoncom.New('InternetExplorer.Application')
wo.QueryInterface('{3050F673-98B5-11CF-BB82-00AA00BDCE0B}')

But got the following error:

pywintypes.com_error: (-2147467262, 'No such interface supported', None, None)

Any idea on how to address this problem?

Thanks, xin
