** Note this post is about the MQMD.PutDateTime being read-only with the amqmdnet.dll assembly and read-write in the MQAX ActiveX Component.
I am trying to get some control of the MQMD fields when putting a message to the queue. I can get to all of fields that I want to modify except the PutDateTime field, which in MQAX is a read-write field and in amqmdnet the assembly it is a read-only field per the object browser. Why?
The following VB.Net code shows a Invalid Date Time in Queue Browser MQ Explorer and while stepping through the code the PutDateTime property shows:
| Code: |
| <error: an exception of type: {System.FormatException} occurred> Date |
This occurs on CSD07 and CSD08.
Any Ideas? This is one of the final hurdles in porting my code to .Net.
Any response is greatly appreciated!!
Thanks,
Eric
Here is the function:
| Code: |
Public Overridable Function PutMessage(ByVal MessageData As String) As Int32
Dim mqQMgr As MQQueueManager '* MQQueueManager instance
Dim mqQueue As MQQueue '* MQQueue instance
Dim mqMsg As MQMessage '* MQMessage instance
Dim mqPutMsgOpts As MQPutMessageOptions '* MQPutMessageOptions instance
'* Try to create an MQQueueManager instance
Try
mqQMgr = New MQQueueManager(_QMgrName)
mqQueue = mqQMgr.AccessQueue(_QueueName, MQOO_OUTPUT + MQOO_FAIL_IF_QUIESCING _
+ MQOO_SET_ALL_CONTEXT + MQPMO_PASS_IDENTITY_CONTEXT)
Catch mqe As MQException
Return (mqe.Reason)
End Try
Try
'MQ Message Object
mqMsg = New MQMessage
With mqMsg
.ApplicationIdData = "ApplIdData123456890ABCDEF1234568"
.ApplicationOriginData = "1234"
.Format = MQFMT_STRING
.PutApplicationName = "Put Msg App"
.PutApplicationType = MQAT_WINDOWS_NT
.CharacterSet = CODESET_437
.Encoding = MQENC_NATIVE
.UserId = "HardCoded ID"
.Priority = MQPRI_PRIORITY_AS_Q_DEF
.Persistence = MQPER_PERSISTENCE_AS_Q_DEF
.WriteString(MessageData)
End With
' Put Message Options
mqPutMsgOpts = New MQPutMessageOptions
mqPutMsgOpts.Options = mqPutMsgOpts.Options _
+ MQPMO_NEW_MSG_ID + MQPMO_NEW_CORREL_ID _
+ MQPMO_SET_ALL_CONTEXT
'Put Message to the Queue
mqQueue.Put(mqMsg, mqPutMsgOpts)
Return mqQueue.ReasonCode()
Catch mqe As MQException
Return (mqe.Reason)
Finally
' Close Queue & Queue Manager
mqQueue.Close()
mqQMgr.Close()
' Cleam up objects, no dispose objects available
mqQMgr = Nothing
mqQueue = Nothing
mqMsg = Nothing
mqPutMsgOpts = Nothing
End Try
End Function

I understand that you get a system format exception.
If you are expecting your date to be in standard locale windows format that is reassuring and should be so.
Remember as well that your date is always in UTC time zone. So you will have to translate it to the local time zone to make it meaningfull to you.
Enjoy  |

I have updated my function (see first post) and am getting blanks for the Date and Time when running amqsbcg, any other ideas?

Since you have specified SET_ALL_CONTEXT you must set the mqmd putdate and puttime in GMT in character format
The format used for the date when this field is generated by the queue manager is:
YYYYMMDD
where the characters represent:
YYYY
year (four numeric digits)
MM
month of year (01 through 12)
DD
day of month (01 through 31)
The format used for the time when this field is generated by the queue manager is:
HHMMSSTH
where the characters represent (in order):
HH
hours (00 through 23)
MM
minutes (00 through 59)
SS
seconds (00 through 59; see note below)
T
tenths of a second (0 through 9)
H
hundredths of a second (0 through 9)

I totally agree with that the but the property is read-only and that is why I was also wondering if there was a bug in amqmdnet.
Per the Object Browser:
amqmdnet
| Code: |
Public ReadOnly Property PutDateTime() As Date
Member of: IBM.WMQ.MQMessage
|
MQAX
| Code: |
Public Overridable Property PutDateTime() As Object
Member of: MQAX200.MQMessage
|
Here is the data on the assembly:
Run-Time Version=v1.1.4322
Version=1.0.0.3 |

| It is readonly in the .net library - you would need to talk to IBM and get a requirement raised to get this property modifiable (assuming it makes sense for it to be writable as well!).... |

I know nothing about MQAX but I agree that it doesn't make much sense for some but not all of the origin context fields to be settable.
I suggest modifying the title of this thread to make it clear that it relates to MQAX so that those that do know about it notice the thread.
You could also raise a problem with the IBM support centre.

| BTW This isnt MQAX but amqmdnet.dll, ie the .NET interface. MQAX came up just as a comparison |

I support MQ on CICS and zOS - all of these other fancy interfaces are a mystery to me

Well here is IBM's Response to the issue.
| Quote: |
Hello Eric,
Right now at our current code level it appears that there is no way within our code to set the PUT date and time.
Below is the response of the Change Team to your last question.
.
Unfortunately the customer will have to find another way around this problem, as the current .NET interface does not support a writable putdatatime field. MQ doesn't guarantee that support for all features is possible from all languages, and although we try hard this is just something which needs to be done through the requirements process. Perhaps the requirement could request that any change gets back ported to 5.3, but you would still be looking at some time in the future.
Regards,
Jason
.
I have emailed you a Design Change Request form. Please let me know if you intend to submit the form or would just like the PMR closed. |

Please do raise it as a DCR - it makes sense to do it, but its an external change hence the need for the requirement. I have already primed the development team, but changes are prioritized based on customer demand.

Well we just have to wait and see if it becomes a reality. Here is what I got back from IBM after my submission of the request.

Thank you for submitting an MQSeries Requirement.
We have reviewed your requirement and have the following
response:
Accepted- IBM agrees with the request and a solution is desirable and feasible.
IBM intends to provide a solution. However, IBM's plans may change, and no commitment is made that a solution will be provided.
This will be fixed in the next release of WMQ
Please quote reference number: R3302

If the need is urgent, you could probably (fairly easily) make your own .NET library for MQ:
Get Lutz Roeder's .NET Reflector (http://www.aisto.com/roeder/dotnet/), and the Reflector.FileDisassembler addin from http://www.freewebs.com/csharp/Reflector/AddIns/.
Open amqmdnet.dll in .NET Reflector, dump the disassembly to files, add the appropriate set method, and recompile. |
