Can anyone help me?
I am trying to write a Powerbuilder application and I am coming across a couple issues with MQ.
1) How do I connect to a remote queue, my local queue connection is find, but I get an error when I try a remote queue.
2) I need to determine how many messages are on the queue before I do a get
3) How do I set syncpoints?
I hope someone out there can help me, I have little experience with MQ and would greatly appreciate the help. |

| Can you add some details on PowerBuilder. I personally have no experience with such. What programming language is used? |

The application itself is in the computer language powerbuilder. It is an Object Oriented language. I am creating OLE object that are going to be doing the work for me, but when I go to connect to the OLE object it is blowing me out of my program. Here is some sample code:
ole_mq_queue_mgr = ole_mq_session.AccessQueueManager(is_queuemgr)
This is the line of code that is not working for connecting to the remote queue. |

| I am not really trying to connect to a remote queue manager, I am connecting to my local manager, once the message is put on that queue it gets send (behind the scenes) to another queue on another manager. The queue manager for the queue that is giving me problems is the same as the other queues that I can connect to. |

It is an error that says null Object Reference, saing that the object is not there. I created the object using the following code (queue and manager):
// Queue Manager - To represent a connection to a queue manager.
ole_mq_queue_mgr = CREATE oleobject
ll_Ret = ole_mq_queue_mgr.ConnectToNewObject("MQAX200.MQQueueManager")
if ll_Ret <> 0 then
dw_header.object.as_activity[1] = ls_Activity + "~r~n" + "Encountered error connecting to MQQueueManager object with return: " + String(ll_Ret)
of_cleanup()
return -1
end if
// Queue - To represent an MQSeries queue.
ole_mq_queue = CREATE oleobject
ll_Ret = ole_mq_queue.ConnectToNewObject("MQAX200.MQQueue")
if ll_Ret <> 0 then
dw_header.object.as_activity[1] = ls_Activity + "~r~n" + "Encountered error connecting to MQQueue object with return: " + String(ll_Ret)
of_cleanup()
return -1
end if |

| ... hmmm ... one doesn't normally create an MQQueue object, one normally accesses an MQQueue object (gets a reference to one) from the MQQueueManager object. Which exact statement failed? |

THe line that failed was this
ole_mq_queue_mgr = ole_mq_session.AccessQueueManager(is_queuemgr)
This line is in my connect function, those lines before were in the function to create the messages. How would I go about getting a reference through the queue manager. Like i said before I really don't know to much about MQ.
What exactly do you do for a living? |

The line you list doesn't appear in the code fragment you supplied.
The following link from the MQSeries COM book illustrates the properties and methods on the MQQueueManager object. One of the methods is AccessQueue which returns an MQQueue object owned by the queue manager. |

Thanks for that web site, I am going to look around and see if I can get anything from that. I was wondering if you knew anything about creating sync point (unit of work). Also, I need a way to determine the amount of messages on a queue before I do a get on the queue.
Any help on those? |

To go with the other message I posted, see above...
I think I am already using the AccessQueue Method.
Here is my code:
ole_mq_queue_mgr = ole_mq_session.AccessQueueManager(is_queuemgr)
ole_mq_queue = ole_mq_queue_mgr.AccessQueue(is_queue, 16 + 1)
The error that I am getting is on the AccessQueueManager, I guess I am trying to access the queue through the session.
Does this help any? |

| What is the value of the variable being passed to the AccessQueueManager()? Is it the exact same case as the local queue manager? Is the queue manager located on the same machine as the application? Does the IBM supplied binary amqsput work to put a message to a test queue? |

The value I am passing is the name os the queue manager.
Is it the exact same case as the local queue manager?
Yes
Is the queue manager located on the same machine as the application?
No
Does the IBM supplied binary amqsput work to put a message to a test queue?
I am not sure if it does or not, I would need to investigate, what is amqsput?
