Magic xpa's Messaging Capability (Magic xpa 3.x)

In each of the supported message queuing systems, Magic xpa provides four basic programs:

• Open Queue

• Send Message

• Read Message

• Close Queue

A very basic “read message” program may be comprised of the following program calls: Open Queue, Read Message, Close Queue.

In addition, the component provides a Quick Send program, which opens a queue, sends a message, and closes the queue.

Each Open Queue program returns a queue handle, a numeric value, which is a number that identifies the connection to that open queue. Every interaction with that Open Queue is now performed using this handle.

Apart from the basic programs, the component provides additional programs, which differ according to the message queue system.
