problem in event handling on change of variable value.

Thu Apr 17 09:19:20 EDT 2014

hello sirjee,
i have read You solution for handling of events from CANoe in python.
I've implemented and its work correctly when I waiting in a msgbox (0, 
"Finished the Test", "Info", 16).
I will implement it in a loop with a sleep time. The standard python 
function of the sleep blocks the actual task and the event handling dosn't 
work.
Now I search for a solution to start the event class in a extra task with 
treahding.Thread. 
I've write a simple claas for testing of this:
class Tester (threading.Thread):
 def __init__ (self, variable):
 threading.Thread.__init__ (self)
 self.__debug = True
 self.__env_event = None
 self.__appl = win32com.client.Dispatch 
('CANoe.Application')
 self.__env = self.__appl.Environment
 self.__var_name = variable
 self.__var = self.__env.GetVariable (variable)
 def run (self):
 if self.__var != None:
 self.__env_event = win32com.client.WithEvents 
(self.__var, Tester)
 print 'run'
 i = 0
 while True:
 pass
 time.sleep (10)
 print i
 i = i + 1
 def OnChange (self, value):
 if self._debug: print ('VariableEvents:OnChange now called 
with %s' %value)
a = Tester ('dummy')
a.start ()
The run() dosn't work. I can't register the COM event. Have You a solution 
for this?
The claas tester works without self.__env_event = 
win32com.client.WithEvents (self.__var, Tester).
Regards,
Bernd
