Hello,
I am trying to get a particular message from a Queue.The Queue is opened in BROWSE Mode.I want to retrieve a particular message from the Queue.
I have to set these? How to set these values in order to get a particular message?
queueMessage.CorrelationId;
queueMessage.MessageId;
queueMessage.MessageSequenceNumber;
(OR) Any method is there?
I am doing it in .NET.
Please Help,
Vijay... |

i do not see a good balance between what you try yourself to solve the problem, and the amount of help you are trying to get from this forum.
at least i quit "support" at this point because i do not see a real effort from your end trying to solve the problem before asking here.
If you really had read the manuals and had a look at the samples, then your questions would sound different.
just my 2 cents, dont want to offend you, others may still help.

| Try looking at the amqsecha.c sample. It manipulates the message id and correlation id. |

I want to get the Next Message,Next Message while I click Next Message button fot that I have got the Message id and Corelated Id. How to Increment them both?
I have opened the Queue in BROWSE Mode.
This is what I Did:
int mid=MQC.MQRO_PASS_MSG_ID;
int cid=MQC.MQRO_PASS_CORREL_ID;
mid++;cid++;
queueGetMessageOptions.Options = MQC.MQGMO_BROWSE_NEXT;
queue.Get(queueMessage, queueGetMessageOptions);
txtGetData.Text=queueMessage.ReadString(queueMessage.MessageLength);
But it is not Going to the Next message.
Please Help,
Thanks,
Vijay... |

If all you want to do is get the next message, then you don't need to do anything with the message id and correlation id other than set them to none. The "default behavior" of WMQ is to get the next message.
I'd suggest (again and as have others) that you take a look at the samples. amqsget0.c is the sample that gets messages. |

| You might also want to look at the application programming guide and reference where they discuss the id's. They are not fields that you 'increment' to get the next one. They are based on several things (one of them being timestamp). |

I will be pressing the Button 'NEXT', and click one more time NEXT and one more time NEXT so the messages have to be displayed one by one in the TextBox, Each one at a time.So please tell me.This is my requirement.
Thanks in Advance,
Vijay.... |

yes. just press next and you get the next message. this is exactly how MQ works. Every time you press next something is incremented so you get the next message. for details, please check the MQ documentation.
i am just curious. do you make your living from this? who gives you this requirements? or is this just homework? what is your profession? have you ever considered looking at samples or the documentation? what do you think these forums are for?

Your posts demonstrate to me that you need some basic WMQ training. I'd suggest taking an MQ application programming course. IBM offers a variety of 3-day, hands-on lab exercise courses.
Visit www.ibm.com/training. Enter the course code from the list below.
MQ052 WMQ Application Programming (UNIX)
MQ054 WMQ Application Programming (z/OS)
MQ057 WMQ Application Programming (Windows)
MQ096: WebSphere MQ Application Programming Using Base Classes for Java
MQ140: WebSphere MQ Programming Using the JMS

I have opened the Queue like this:
queue = queueManager.AccessQueue( txtQueueName.Text, MQC.MQOO_BROWSE | MQC.MQOO_FAIL_IF_QUIESCING );
queueMessage = new MQMessage();
queueMessage.Format = MQC.MQFMT_STRING;
queueGetMessageOptions = new MQGetMessageOptions();
queueGetMessageOptions.Options = MQC.MQGMO_BROWSE_NEXT;
queue.Get(queueMessage, queueGetMessageOptions);
txtQueueMessage.Text=queueMessage.ReadString(queueMessage.MessageLength); |
