how to get the NT event log properties with OnObjectReady() with python

[hainguyen2x]

I'm trying to get a notification from the NT event for any new event
using the DispatchWithEve nts() function. Everything seems to be
working the way I wanted, but I don't know how to get the properties
of the event (ie. event type, message, etc.) from the OnObjectReady()
callback.

class SinkClass(objec t):
def OnObjectReady(s elf, *args): #self may be the wmi_sink object
print "OnObjectRe ady callback ..."
print self #.TargetInstanc e.Message
print args[0]

def OnCompleted(sel f, *args):
print "OnComplete d callback..."
print args #.TargetInstanc e.Message

def OnObjectPut(sel f, *args):
print "OnObjectPu t callback..."

def OnProgress(self , *args):
print "OnProgress callback..."

wmi = win32com.client .GetObject("win mgmts:
{impersonationL evel=impersonat e,(security)}!//./root/cimv2")
wmi_sink =
win32com.client .DispatchWithEv ents("WbemScrip ting.SWbemSink" ,SinkClass)
wmi.ExecNotific ationQueryAsync (wmi_sink,"SELE CT * FROM
__InstanceCreat ionEvent where TargetInstance ISA 'Win32_NTLogEve nt'")
The argument args in the OnObjectReady() seems to be the interface to
a com object (may be the event object itself).
I want to read the properties (ie. message, eventID, type, etc) of
the triggered NT event.

Please help.

The first arg is passed as a raw IDispatch interface. You can wrap it
as below to access the properties.

def OnObjectReady(s elf, *args): #self may be the wmi_sink object
print "OnObjectRe ady callback ..."
print self #.TargetInstanc e.Message
wbem_object=win 32com.client.ge ncache.EnsureDi spatch(args[0],0)
print wbem_object
ti=wbem_object. Properties_('Ta rgetInstance'). Value
print 'TargetInstance ',ti
for p in ti.Properties_:
print p.Name, p.Value
