[Tutor] COM & IE problems

[Aaron Colichia]

I've been using win32com.client to work with IE via COM, but recently had a
need to start using comtypes.client because it provides a better wrapper for
IE.
However, when I want to grab an existing IE using
comtypes.client.GetActiveObject() the result is always the same as
illustrated below

H:\devel\workspace\web\src>python
Python 2.5.2 (r252:60911, Feb 21 2008, 13:11:45) [MSC v.1310 32 bit (Intel)]

>>> import comtypes.client
>>> ie = comtypes.client.CreateObject('InternetExplorer.Application')
>>> ie.visible = True
>>> ie.__clsid
'{0002DF01-0000-0000-C000-000000000046}'
>>> ie._iid_
GUID("{D30C1661-CDAF-11D0-8A3E-00C04FC9E26E}")
>>> newie = comtypes.client.GetActiveObject('InternetExplorer.Application')
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "c:\python25\lib\site-packages\comtypes\client\__init__.py", line

 GetActiveObject
    obj = comtypes.GetActiveObject(clsid, interface=interface)

    oledll.oleaut32.GetActiveObject(byref(clsid), None, byref(p))

Has anyone got any bright ideas on how to get this working properly?  I
really appreciate any help.
