[python-win32] Using COM Event. A problem

[NIcola Montecchiari]

Dear All,

I am trying to create a call back for som events generated by a COM server
that I connect.
Looking at some posts apparently related to the same topic, I wrote this
sample code to test:

import win32com.client as com
from win32com.client import gencache

class Eventi:
    def Device_Notify(self,EventCode):
       if EventCode==0:
         print "begin"
       elif EventCode==1:
         print "end"

mod = gencache.EnsureModule('{B4955EC7-F7F2-11D2-AA9C-444553540000}', 0, 1,
0)
ob = mod.Application()
objCybio = com.DispatchWithEvents(ob, Eventi)

When I run this code, it starts the connection, but soon after it is
stopped with the following error:

Traceback (most recent call last):
  File "evento.py", line 13, in <module>
    objCybio = com.DispatchWithEvents(ob, Eventi)
  File "D:\Python27\lib\site-packages\win32com\client\__init__.py", line
256, in
 DispatchWithEvents
    raise TypeError("This COM object can not automate the makepy process -
please run makepy manually for this object")
TypeError: This COM object can not automate the makepy process - please run
makepy manually for this object

I did run the makepy, but still the same error.
Do you have any suggestion of what it could be wrong?

Thanks a lot for your help

Nicola
