hello
I'm using MQMF_SEGMENTATION_ALLOWED for big Message. when I put successfully, but when I get I doesn't
// when put message
mqMsg = New MQMessage
mqMsg.WriteString(strMessage)
mqMsg.Format = MQFMT_STRING
mqMsg.MessageFlags = MQMF_SEGMENTATION_ALLOWED
mqPutMsgOpts = New MQPutMessageOptions
mqPutMsgOpts.Version = MQMD_VERSION_2
mqQueue.Put(mqMsg, mqPutMsgOpts)
mqQMgr.Commit()
// It segment 3 messages
// But when I get ,
mqMsg = New MQMessage
mqGetMsgOpts = New MQGetMessageOptions
mqGetMsgOpts.WaitInterval = 15000
mqGetMsgOpts.Options = MQGMO_SYNCPOINT + MQGMO_ALL_SEGMENTS_AVAILABLE + MQGMO_WAIT
mqGetMsgOpts.Version = MQC.MQGMO_VERSION_2
Dim str As String
mqQueue.Get(mqMsg, mqGetMsgOpts)
str = mqMsg.ReadString(mqMsg.MessageLength)
//the result : str = MDE..
//althought message on Queue disappear but string reveived is MDE
if I change some option it show compcode=2257 |

Add the following to the get code.
mqMsg.setVersion(MQC.MQMD_VERSION_2)
Remember any grouped/segmenting of messages must be MD2. Should work after that.

Is this on the same Queue Manager.
2257 says you are using options from a V2 MQMD but only supplying a V1.
Apart from the previous suggestion, you could try the latest version of the Java code. I seem to remember that the earlier versions always used a V1 MQMD by default, where the later ones used the 'highest' supported by the platform you connect to.
Cheers,

thank EddieA and mqonnet
I'm sorry, I have used VB.net for programming not Java. I see code in VB.net similar to JAVA so I ask you.
mqonnet tell me mqMsg.setVersion(MQC.MQMD_VERSION_2) but in VB.net it doesn't have that method. Only method mqMsg.version but readonly
today thank God I have passed it I set more messageflag when I get
this source:
mqMsg = New MQMessage
mqMsg.MessageFlags = MQMF_SEGMENTATION_ALLOWED
mqGetMsgOpts = New MQGetMessageOptions
mqGetMsgOpts.WaitInterval = 15000 '* 15 second limit for waiting
mqGetMsgOpts.Options = MQGMO_LOGICAL_ORDER
mqGetMsgOpts.Options = mqGetMsgOpts.Options + MQC.MQGMO_SYNCPOINT
mqGetMsgOpts.Options = mqGetMsgOpts.Options + MQGMO_ALL_MSGS_AVAILABLE
mqGetMsgOpts.Version = MQC.MQGMO_VERSION_2
While (mqe.Reason <> MQRC_NO_MSG_AVAILABLE)
Try
mqQueue.Get(mqMsg, mqGetMsgOpts)
str = mqMsg.ReadString(mqMsg.MessageLength)
Catch mqe
'* report the error
End Try
End While
mqQueue.Close()
End Sub |

I havent used VB.net myself, but i would expect VB to be on the same lines as C/C++ and be using similar function calls etc. Since your code looked more like Java, i gave you the method in java that does the job for you.
From your recent post it is not very clear if your problem is solved or not. But in any case, i would recommend going through the sample apps supplied for VB. It looked more like C samples. In which case, you may as well do something like Md.Version = 2. Double check this in the respective manuals/samples.
Cheers
