Hint : what is the name of your TriggerMessage instance in the above code ? I think that what you wannt is more like this : import struct class TriggerMessage(object): def __init__(self,data): """ Unpacks the passed binary data based on the MQTCM2 format dictated in the MQ Application Programming Reference """ self._format = '4s 4s 48s 48s 64s 4s 256s 128s 128s 48s' self._data = data (self.version, self.qname, self.processname, self.triggerdata, self.appltype, self.applid, self.envdata, self.userdata, self.qmgr) = self._decode() def _decode(self): assert len(self._data) == struct.calcsize(self._format) return struct.unpack(self._format, self._data) # test code # data = ??? test=TriggerMessage(data) var = test.qname -- http://mail.python.org/mailman/listinfo/python-list
