[python-win32] Success with COM Connection Point event handling

[Craig H. Anderson]

I want to report that I've had success
with COM Connection Point event handling.
I ran makepy.py on the vendor DLL and it generated the event
method signatures used in class IvrEventHandler 

Thanks again to Mark Hammond for the wonderful software and
answering my questions. 

Code fragments from my working script: 

class IvrEventHandler:
   target = None # must be set to object that handles 
OnPDSBadData(),OnPDSEvent()
   def __init__(self):
       pass
   def OnPDSBadData(self,
                    cause=pythoncom.Empty,
                    Msg=pythoncom.Empty):
       IvrEventHandler.target.OnPDSBadData(cause,Msg)
   def OnPDSEvent(self,
                  ErrFlag=pythoncom.Empty,
                  command=pythoncom.Empty,
                  CmdType=pythoncom.Empty,
                  data=pythoncom.Empty):
       IvrEventHandler.target.OnPDSEvent(ErrFlag,command,CmdType,data) 

class TestClass:
  def Run(self):
       self.SerStart = win32com.client.Dispatch('VRNexusS.IServerStartup')
       self.IVRNexus = self.SerStart.GetIVRNexus
       self.VrServer = 
win32com.client.DispatchWithEvents(self.IVRNexus,IvrEventHandler) 

       for ii in range(60):
           time.sleep(1)
