You could start by giving us some more information on versions and platforms! Perhaps even the full error message? 
I'd guess that either the installation has an issue, or you're using a version of client/.NET libs that doesn't match/support the queue manager version.
But from the detail of your post it could as easily be pixies in the wires.

Aha!
Are you using the XMS libs? I notice from the IBM site that's not (yet) supported for v7
I'd also try pulling down the v7 client and see if you have more luck with that.

If you're connecting directly (and your code snippet doesn't contain the value of strProperty) why is there a channel definition in the hashtable?

Well if the transport you're using is client (as you've still not posted) then it won't! 
Randomly removing lines of code is not a troubleshooting strategy likely to succeed.

It's probably also worth underlining that when I say client, I don't mean client in the database sense; I know you're connecting directly to the queue manager. What I'm saying is that I believe you're establishing a client connection to the queue manager, and this is what's failing for the reasons I theorise above.

even why it is showing "amqmdxcs" format is invalid |

Yes I guessed that. You still have not answered the question of what kind of connection you're making.

Potentially nothing. That's why I keep banging on about connection types and versions.

Did you not see my earlier post above about versions?
This is going to be much more helpful if you a) read what I'm posting & b) provide the information requested.

Hi,
how should i come to know which connectivity i am using (XMS). Please help me know. This code was written by one of my team mates. he used some of the ibm.wmq for connecting to the web sphere. Please let me know how should i answer to your query.
application: .net 1.1 (console)
web sphere: 7.0 windows
Even on my machine ibm web pshere is not installed. i copy the code and run on the server. |

XMS is not a connectivity method; I also said several posts ago that it's not supported for v7.

How many times must I point out you've not posted the transport property?

I consider it unlikely he'd have used anything else. He probably realised plastic tube was a bad idea.

And this has nothing to do with connection type. Nothing. A basic knowledge of WMQ programming would tell you that.
Read the .NET manual, the Application Programming Guide, the sample code and my earlier posts.

At last! It's like getting detailed user requirements out of an auditor!
Well, no, not that tricky.
So you are using a client connection as I suspected all along. Use a v7 client as I suggested what seems like years ago. It's backward compatable with v6. And cross your fingers the XMS holds on v7.
