interface to win job scheduler portable from win98 .. winXP / cmdline or COM ?

[Robert]

this COM interface seems to be right for my problem. but I don't get a
handle on it.
I am only familiar with things like
o=win32com.client.Dispatch("Excel.Application") and navigate.
Is it possible this way? I didn't find anywhere a hint for such
exported Class Name.
I only found a "CLSID" and know little about that. I tried the
following. But he says "interface not supported" but seems that he
finds anything ... ?


>>> from win32com.client import Dispatch
>>> Dispatch("{148BD520-A2AB-11CE-B11F-00AA00530503}")
Traceback (most recent call last):
  File "<interactive input>", line 1, in ?
  File "C:\PYTHON23\lib\site-packages\win32com\client\__init__.py",
line 95, in Dispatch
    dispatch, userName =
dynamic._GetGoodDispatchAndUserName(dispatch,userName,clsctx)
  File "C:\PYTHON23\lib\site-packages\win32com\client\dynamic.py",
line 85, in _GetGoodDispatchAndUserName
    return (_GetGoodDispatch(IDispatch, clsctx), userName)
  File "C:\PYTHON23\lib\site-packages\win32com\client\dynamic.py",
line 73, in _GetGoodDispatch
    IDispatch = pythoncom.CoCreateInstance(IDispatch, None, clsctx,
pythoncom.IID_IDispatch)
com_error: (-2147467262, 'Schnittstelle nicht unterst\xfctzt', None,
