(Read-only, introduced in MSMQ 3.0.) The PROPID_MGMT_QUEUE_EOD_LAST_ACK_COUNT property returns the number of times that the last order acknowledgment for a message sent from the computer to the queue was received.

Property ID

PROPID_MGMT_QUEUE_EOD_LAST_ACK_COUNT

Type Indicator

VT_UI4

MQPROPVARIANT Field

ulVal

Property Value

The number of times that the last order acknowledgment was received (VT_NULL is returned if the queue is a local queue on the computer).

Remarks

To retrieve the number of times that the last order acknowledgment for a message sent from the computer to the queue was received, include PROPID_MGMT_QUEUE_EOD_LAST_ACK_COUNT in an 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 this information for a queue that does not contain messages and is not opened by an application.

Equivalent COM Property

When using COM components, you can retrieve the number of times that the last order acknowledgment was received by examining the EodLastAckCount element of the MSMQCollection object returned by the MSMQOutgoingQueueManagement.EodGetSendInfo method.

Example Code

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

aMgmtPropId[i] = PROPID_MGMT_QUEUE_EOD_LAST_ACK_COUNT;    // Property ID  
aMgmtPropVar[i].vt = VT_NULL;                             // Type indicator  
i++;
