Property Values

Time at which the properties of the queue were last set.

Remarks

The PROPID_Q_MODIFY_TIMEproperty is set by MSMQ when MQCreateQueueis called and is then reset by MSMQ each time the properties of the queue are modified by calls to MQSetQueueProperties.

The time returned by MSMQ is the number of seconds elapsed since midnight (00:00:00), January 1, 1970 (Coordinated Universal time) according to the system clock.

To retrieve the date and time at which the queue properties were last modified, specify PROPID_Q_MODIFY_TIME in the MQQUEUEPROPSstructure; then call MQGetQueuePropertiesand examine its returned value.

An MQ_ERROR_PROPERTY_NOTALLOWED error is returned if an attempt is made to set this property.

Examples

This example shows how PROPID_Q_MODIFY_TIMEis specified in the MQQUEUEPROPSstructure for retrieving the date and time when the properties of the queue were last modified.

Copy Code 
aPropID[i] = PROPID_Q_MODIFY_TIME; // Property identifier
aVariant[i].vt = VT_I4; 		 // Type indicator
