The following table lists the elements of MSMQ that require special attention when used as part of a transaction:
| Element | Description |
|---|---|
| MQCreateQueue | Creates a transaction queue (see PROPID_Q_TRANSACTION). |
| MQSendMessage | Sends transactional messages (see pTransaction parameter) to a transaction queue. |
| MQReceiveMessage | Retrieves transactional messages (see pTransaction parameter) from a transaction queue. |
| PROPID_M_PRIORITY | MSMQ sets the message priority of all transactional messages to 0. |
| PROPID_M_DELIVERY | MSMQ sets the delivery property of all transaction messages to MQMSG_DELIVERY_RECOVERABLE. |
| PROPID_M_TIME_TO_BE_RECEIVED | MSMQ sets the message's time-to-be-received property to the setting of the first transaction message sent. |
| PROPID_M_TIME_TO_REACH_QUEUE | MSMQ sets the message's time-to-reach-queue property to the setting of the first transaction message sent. |
| PROPID_M_JOURNAL | This property is disregarded when sending transaction messages. MSMQ automatically sends undelivered transaction messages to the transaction dead letter queue (DEADXACT) on the source computer. |
