[python-win32] Client site not available

[Garth Johnson]

Ok.  I have requested and now received a newer version of the OCX 
control (from the vendors) that DOES work with VBScript when executed 
from wscript/cscript.  The PortOpen property now responds correctly 
without getting the aforementioned error - and this is a definite 
improvement.

However, 2 things still elude me.

1) I wish to be able to use the events available in the object as well, 
and after much reading  (and purchasing of your book, Mark - which 
helped ALOT in several other areas - thank you!) I was left feeling a 
bit lost in the 'events' arena.  Here is the code I am attempting (short 
and simple) atm, which responds with "AttributeError: 
'<win32com.client.COMEventClass instance at 0x12436112>' object has no 
attribute '_typelib_guid_'":

################## Code snippet [start]
from win32com.client import DispatchWithEvents
class SwiperEvents(object):
    def OnCardDataChanged(self,
                          Source=pythoncom.Missing,
                          CursorType=pythoncom.Missing,
                          LockType=pythoncom.Missing,
                          Options=pythoncom.Missing,
                          adStatus=pythoncom.Missing,
                          pCommand=pythoncom.Missing,
                          pRecordset=pythoncom.Missing,
                          pConnection=pythoncom.Missing):
        print "Handler called!"
swiper = DispatchWithEvents('ctlUSBHID.USBHID', SwiperEvents)
################## Code snippet [end]

I have a bad feeling this is an obvious error on my part - but am still 
too new at Python I guess.

2) (and this is probably related to the first thing) - when I monitor 
the CardData property for changes 'manually' (with a loop) it never 
changes - no matter how many card swipes I attempt.  COULD this be a 
result of the PortOpen property not actually making the necessary 
connection in the OCX and just 'acting' like it was set?:

PS Oh -  and I DID fully remove the old OCX AND the Makepy output before 
rebuilding it - and tested for the correct version of the control from 
wscript with vbscript test code they sent me (which looks essentially 
the same as the web page one).
