The first arg is passed as a raw IDispatch interface. You can wrap it
as below to access the properties.
def OnObjectReady(self, *args): #self may be the wmi_sink object
print "OnObjectReady callback ..."
print self #.TargetInstance.Message
wbem_object=win32com.client.gencache.EnsureDispatch(args[0],0)
print wbem_object
ti=wbem_object.Properties_('TargetInstance').Value
print 'TargetInstance',ti
for p in ti.Properties_:
print p.Name, p.Value
