(Read-only, introduced in MSMQ 3.0.) The PROPID_MGMT_QUEUE_BYTES_IN_JOURNAL property returns the number of message bytes in the queue journal.

Property ID

PROPID_MGMT_QUEUE_BYTES_IN_JOURNAL

Type Indicator

VT_UI4

MQPROPVARIANT Field

ulVal

Property Value

Number of message bytes in the queue journal.

Remarks

To retrieve the number of message bytes in the queue journal, include PROPID_MGMT_QUEUE_BYTES_IN_JOURNAL in the MQMGMTPROPS structure, call MQMgmtGetInfo, and then examine the value returned.

This property can be retrieved only for an active queue. MQMgmtGetInfo will return a non-specific error (MQ_ERROR) if your application attempts to retrieve the number of message bytes in the journal of a queue that does not contain messages and is not opened by an application.

The journal quota of a queue, or the maximum number of bytes that can be stored in the journal, is set by the PROPID_Q_JOURNAL_QUOTA property of the queue.

Equivalent COM Property

When using COM components, you can retrieve the number of message bytes in a queue journal using the MSMQQueueManagement.BytesInJournal property.

Example Code

The following code fragment shows how PROPID_MGMT_QUEUE_BYTES_IN_JOURNAL is specified in arrays that can be used to initialize an MQMGMTPROPS structure.

aMgmtPropID[i] = PROPID_MGMT_QUEUE_BYTES_IN_JOURNAL;    // Property identifier  
aMgmtPropVar[i].vt = VT_NULL;                           // Type indicator  
i++;
