Which variables return warning number and description in OnWarning Event Handler?

Hi All,

When there's an execution error in our SSIS 2012 packages, we use the OnError event handler to run a stored procedure that logs the error using the variables System::ErrorCode and System::ErrorDescription to a user-defined table.  Now we want to also log SSIS warnings to that same table.  Which variables do I use in the OnWarning event handler?  I don't see any system variables with "warning" in the name.

We don't want to use SSIS built-in logging because those records wouldn't get logged out our user-defined table.

Thanks,
Eric B.
