i dont understand
what did you receive? what did you expect? how do you know, that the message you got is not the message you should have got?
show all your code relevant to the mqget.
do you wipe out msgid and correlid before mqget?

here are the complete code i used to browse message in que..
queueManager = new MQQueueManager(queueManagerName, channelName, connectionName);
queue = queueManager.AccessQueue(queueName, MQC.MQOO_BROWSE + MQC.MQOO_FAIL_IF_QUIESCING);
MQMessage queueMessage = new MQMessage();
queueMessage.Format = MQC.MQFMT_STRING;
queueGetMessageOptions = new MQGetMessageOptions();
queueGetMessageOptions.Options = MQC.MQGMO_NO_SYNCPOINT + MQC.MQGMO_CONVERT + MQC.MQGMO_NO_WAIT + MQC.MQGMO_FAIL_IF_QUIESCING + MQC.MQGMO_BROWSE_NEXT;
queue.Get(queueMessage, queueGetMessageOptions);
str_rtn = queueMessage.ReadString(queueMessage.MessageLength);
message1 = str_rtn ;
MsgBox.Info(message1);
i get the message but when i view it with message box it will give me only view this data "20101209110432" and symbol.. like this image
Uploaded with ImageShack.us
it return some data and symbol like this when i debug the program..
""20101209110432\0\0\0\0\0\0\0\0QOL0QUEEC1\0\0\0\0\0\0\0\0\0\0dyynx2553e1l2gmeujjwga45\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\01\0\0\0INQ_HOST\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0A........"

| \0 is a non-printable character. |

So your problem is not that the data isn't being returned, it's that the method you're using to display it (a message box) can't handle unprintable characters.
This is a problem with your application code, not with WMQ.
This wheel you're trying to reinvent simply doesn't roll.

yeah i get the message..but if declare it as a string it will produce symbol like that which is will bring to logic error..
how can i solve this thing..??what are the exactly format return when i use this code..??
string str_rtn = queueMessage.ReadString(queueMessage.MessageLength);
in WMQ, this symbol represent character or just a langguage which my computer cannot read and replace with this symbol..??
"\0\0\0\0\0\0"
i did use in c#
str_rtn = strrtn.Replace("\\0","");
to remove that symbol,but still cannot view the message data..
any ideas..?
thanks |

First of all you are browsing a queue and assuming that all messages thereon are text messages...
Like in the Steven Segall movies, assumption is the .... (Dark territories)..
You have noticed that you need to be able to handle text messages (MQFMT_STRING) and messages that are not text messages (MQFMT_NONE).
Those non text messages typically do not carry text so you will need to handle them differently.
Have fun

No, your computer is doing that. WMQ doesn't care about the contents of the data. If the format is string, and you ask it to, WMQ will do certain tricks with it but the bottom line here is that the message you're trying to display contains data which can't be displayed by your computer in a message box.

Fix your code. Or give up and use one of the existing tools that browses message data instead.

Be sure you understand all the implications of doing this. Especially for any other applications that are using the message.
(I'm saying that because you're browsing the message and hence must be writing an administrative application with the actual application further downstream. No application which is the end consumer of the message has any reason to browse in normal use)

This will get worse before it gets better. WMQ is not a simple piece of software. I urge you to get some formal training.

We hear this a lot here.

Though it does sound like you're going in an odd direction that may cause trouble later.

I suppose anything you can implement as working will do. Remember what I said about changing message format.
And the training. I could probably write a Java app (or at least 80% of one) with access to the redbooks & the Internet. Doesn't mean it would be a good app, or a production strength one, but it might produce the results I was looking for...

Then I would suggest you start with JMS. There are good JMS tutorials out there.
