Changing the interface in the wizard to "dual interface" (IUnkown and
IDispatch) does the trick. Now it works as expected.
 
>>> from win32com.client import Dispatch
>>> a = Dispatch("Adder.AddingMachine")
>>> a
<COMObject Adder.AddingMachine>
>>> a.GetValue()
0.0
>>> a.Add(20)
>>> a.GetValue()
20.0
>>> a.Clear()
>>> a.GetValue()
0.0


Before obviously only the IUnkown interface was created. (-> Don't
blindly follow all the instruction of a wizard for creating a toy
example.)
 
Thanks again.
 
Mike
