I uses pywin32

>>> import win32com.client
>>> fm = win32com.client.Dispatch("MCB.PCM")
>>> fm.ReadVariable('dwt')
(True, 0.02500000037252903, u'0.025', u'')

and I am getting it OK.

Now I am trying to add and register event handler and no luck yet :(

>>> ev  = win32com.client.WithEvents(fm, evnt)

class evnt:
    def OnEvent(self):
        print "Hello..."

  
it does not work... I would like to know correct way to register event - any idea?

Thank you very much.
