Indeed, that is the answer JM!
I was thinking to use the Journal Queue as a repository for all sent
messages. However, the message is copied to the journal only when it is
consumed from the queue. In other words, undelivered messages will never get
to go to the Journal Queue, so even if a negative acknowledgment is
received, I won't have the message unless I get it from the Dead Letter
Queue or I keep it in the memory. Obviously, I could use the machine's
Journal Queue and store the messages there. I am pushing for the usage of
Messaging Queues because you have all these methods ("PeekById",
"PeekByCorrelationId", "ReceiveById", "ReceiveByCorrelationId") that would
make search and access easier.Thanks for your heads-up! Regards, Eddie -----Original Message----- From: Discussion of advanced .NET topics. [mailto:[EMAIL PROTECTED] Behalf Of J. Merrill Sent: Thursday, March 23, 2006 5:49 PM To: ADVANCED-DOTNET@DISCUSS.DEVELOP.COM Subject: Re: [ADVANCED-DOTNET] Message Queues and acknowledgment If you created a Message object, isn't the Id property available after Send returns? (If you pass anything other than a Message as the object to be sent, you won't be able to get the Id.) I have not tried this, but nothing else makes much sense.
