Accessing Vista log file "Microsoft-Windows-TaskScheduler/Operatio

Hi,

I am trying to access the log file at
"Microsoft-Windows-TaskScheduler/Operational" in vista using the following
code snippet:

EventLog el = new EventLog();


if
(EventLog.Exists(@"Microsoft-Windows-TaskScheduler/Operational"))
{
// doSomething
}

else
{
MessageBox.Show("not found");
return "";
}

However the code is failing to find the log file inspite of it being there.

Any thoughts on where I am wrong?

Thanks.
Regards,

Soumitra
