Sending Messages

Sending messages in MSMQ is always an asynchronous operation. When you are sure the queue is open, you can continue to send messages, never stopping to wait for a reply.

In addition to the basic asynchronous operation, you can add functionality to your send operation by using:

Message timers to control how long your messages stay in the system
Machine journals to store a copy of the messages you send
Administration queues to receive MSMQ-generated negative and positive acknowledgment messages
Response queues for application-defined response messages
Report queues for tracking

For information on all the message properties that can be used when sending messages with MSMQ API functions, see:
