Public Property UseJournalQueue As Boolean

Property Value

Boolean

true to require that a copy of a message be kept in the originating computer's machine journal after the message has been successfully transmitted (from the originating computer to the next server); otherwise, false. The default is false.

Attributes: MessagingDescriptionAttribute

Exceptions

InvalidOperationException

The message queue is filtered to ignore the UseJournalQueue property.

Examples

The following code example gets and sets the value of a message's UseJournalQueue property.

Remarks

The UseJournalQueue and UseDeadLetterQueue properties specify how Message Queuing tracks a message. If UseJournalQueue is true, then a copy is kept in the computer journal on the originating machine at each step that a message is transmitted.

The sent message is only copied to the journal queue if the destination queue is on a remote computer. If the destination is on the local computer, the message is sent directly to the queue; there are no intermediate steps to require journaling.

When you store messages in a journal queue, clear the queue periodically to remove messages that are no longer needed. Messages stored in journal queues count against the quota for the computer where the queue resides. (The computer quota is set by the administrator.)

You do not create a journal or dead-letter queue. These are both system queues that Message Queuing generates.
