I am writing a Windows App in VB.Net to put messages to the Queue using amqmdnet.dll (v7.0.1). When deploying on some other PCs the program is not putting message to the queue unless I get MQ client installed for those machines.
As it is so inconvenient to install MQ Client on all of my users' machines, is there anyway I can send message to MQ without installing MQ Clients?
Any additional .DLL I can use to put message to the queue to avoid MQ Client installation?
I appreciate your help. Thank you,
Tri |

Inconvenient to install software on client machines? It must be hell everytime they want Microsoft Office or similar.

If you're using .NET look into Managed Connections.

Hi Vitor
Thank you for your valuable response. I've removed MQ Client and tried Managed Client Connection parameter in the connection and I was not able to put message to the queue. It seems that MQ client need to be there or the message will not be sent.
Below is the test function that I used to send message to MQ. Do I need to update any other parameter in the connection?
Private Sub test()
Dim hashConnProperties As New Hashtable()
hashConnProperties.Add(MQC.TRANSPORT_PROPERTY, MQC.TRANSPORT_MQSERIES_MANAGED)
'hashConnProperties.Add(MQC.TRANSPORT_PROPERTY, MQC.TRANSPORT_MQSERIES_XACLIENT)
hashConnProperties.Add(MQC.HOST_NAME_PROPERTY, "IBMMQ_XXX")
hashConnProperties.Add(MQC.CHANNEL_PROPERTY, "SRVR.CONN")
Try
Dim QueueMgr2 As MQQueueManager
QueueMgr2 = New MQQueueManager("MY.QUEUE.MANAGER", hashConnProperties)
Dim OutputQueue2 As MQQueue = Nothing
OutputQueue2 = QueueMgr2.AccessQueue("MY.TEST.QUEUE", MQC.MQOO_INPUT_AS_Q_DEF + MQC.MQOO_OUTPUT + MQC.MQOO_FAIL_IF_QUIESCING)
Dim putMqMsg As MQMessage = New MQMessage
putMqMsg.WriteString("<test>This is a long test<test>")
putMqMsg.Format = MQC.MQFMT_STRING
Dim pmo As MQPutMessageOptions = New MQPutMessageOptions
pmo.Options = MQC.MQPMO_NEW_MSG_ID Or MQC.MQPMO_SYNCPOINT
OutputQueue2.Put(putMqMsg, pmo)
If Not OutputQueue2 Is Nothing Then
'If IsOpen, then Close
If OutputQueue2.IsOpen() Then
OutputQueue2.Close()
End If
End If
If Not QueueMgr2 Is Nothing Then
If QueueMgr2.IsConnected Then
'If Isconnected, then Disconnect
QueueMgr2.Disconnect()
End If
End If
Catch ex As Exception
Throw New Exception(ex.ToString())
End Try
End Sub |

Why not? Was there any kind of error or did you get a dialog box saying "Application just doesn't feel the message putting"

Is that what the documentation says about Managed Connections?

Is that how the documentation says how to set up a managed connection? Does it say that just selecting the Managed option out of the constants is enough?

Hi Vitor,
Thank you for your information. I did some further testing and figured out that it's the option at putting message to the queue
pmo.Options = MQC.MQPMO_NEW_MSG_ID Or MQC.MQPMO_SYNCPOINT
I removed the second option and this works for me: pmo.Options = MQC.MQPMO_NEW_MSG_ID
Before that the program completed without any error notification. However on checking MQ queue I do not see any message in the queue..
Thank you & I appreciate your time.

Before using MQPMO_SYNCPOINT you understand what it means! You would then know why the message was not visible or committed to the queue.

Of course you didn't. That's not an error, that's what you coded.

You are right! I do not understand what it means. I am still in the process of learning and collecting knowledge in this domain. That's why I am here in this forum 
Thank you for pointing out the right direction - Managed client connection.
BTW, I have another question about MQPMO_SYNCPOINT.
This option will allow to commit the transaction when the program completed successfully, or the message will not be visible if any issue. In my case the flow is smooth until the output queue is closed, the queue manager is disconnected and the program completed without any issue. So I wonder why the message was not written to the queue?
Experts I'm waiting for your answer..
Thank you & I appreciate your time.

Did you application issue an explicit or implicit MQCMIT?

You're in the wrong place. We're not equipted to be a training resource nor have we any desire to be. Specific answers to specific questions yes, learning and collecting knowledge you're much better off with a mentor or a training course.
Really. WMB is a complex product and you'll have a terrible time trying to pick it up through here.

I did not issue any implicit / explicit MQCMIT. The test() function in the previous post is all what I have for verifying the issue.
Thanks Bruce!

Hi Vitor, your pointing to "Managed connection" is much better than any training resources

I dont think so! learning should NOT be limitted to training courses or mentors. Beside the job learning processs can be conducted from useful tech forum with agressive experts as well  |

You may want to read up in the infocenter.
I don't believe XA is available for a managed connection at the level of WMQ you are running...

| Thank you fjb_saper. The TRANSPORT_MQSERIES_XACLIENT was commented in the code I posted.. I should have removed it for more clarification. I'll go through the info center.. |

For MQC.MQPMO_SYNCPOINT the code is missing
QueueMgr2.Commit() to write the message to the queue.. |
