Property Values
This property can be set to one of the following values.Value Description MQMSG_SEND_ROUTE_TO_REPORT_QUEUE
Each hop made by the original message generates a report that is recorded in a report message.
The elements of the report are the source Queue Manager, message identifier, target, time, and next hop.
The report message is sent to the report queue specified by the source Queue Manager.
MQMSG_TRACE_NONE
The default. No tracing for this message.
Remarks
If MQMSG_SEND_ROUTE_TO_REPORT_QUEUE is specified but the report queue is not defined by the MSMQ administrator for the source Queue Manager of the message, this property is ignored.
To set where report messages are sent, specify PROPID_M_TRACE in the MQMSGPROPS structure and call MQSendMessage.
To retrieve where report messages are sent, specify PROPID_M_TRACE in the MQMSGPROPS structure. Then call MQReceiveMessage and examine the returned value.
When specifying PROPID_M_TRACE, you can set its Type Indicator to VT_NULL. When the Type Indicator is set to VT_NULL, MSMQ sets the VT field to the appropriate type indicator.
Examples
This example shows how PROPID_M_TRACEis specified in the MQMSGPROPS structure.
aMsgPropId[i] = PROPID_M_TRACE;
aMsgPropVar[i].vt = VT_UI1;
aMsgPropVar[i].bVal = MQMSG_SEND_ROUTE_TO_REPORT_QUEUE;
i++;
Note
OS versions prior to 2.12 require the MSMQ add-on pack.
