Tian:

Thank you very much for your response and concern.  See my answers
inline.

I'm setting ApplicationLogLevel in app.config manually.
EventPublishLogLevel is being set in the call to EventManager.Publish.
Remember that I am using the EIFExceptionPublisher which is a special
exception publisher that works with the logging block.  This is how I
enable it in my app.config:

<exceptionManagement mode="on">
<publisher assembly="Microsoft.ApplicationBlocks.Logging.EIFPublisher"
type="Microsoft.ApplicationBlocks.Logging.EIFPublisher.EIFExceptionPublisher"
include="*" />
</exceptionManagement>

I've read that article and more -- but perhaps I missed something.
How does one set the EventPublishLogLevel when the only call I am
making is:

ExceptionManager.Publish(string Msg)?

At that point, the EIFExceptionPublisher logs an ErrorMessageEvent and
sets the EventPublishLogLevel to 5 (debug).  I see no opportunity to
override that.

Thanks for you help and insight.  I've included the complete
ErrorMessageEvent as it appears in my trace log.  Note that the
EIFExceptionPublisher puts all the exception info that the Exception
Management Application Block generates within the "Message" property
of the ErrorMessageEvent.  Note also -- at the end -- the
EventPublishLogLevel of 5.
