Dear all,
I need to write a VB.NET program to read the message from MQ. However the other side is using JMS to send the message and the FORMAT is MQRFH2.
How can i read the message? need to readbyte? as JMS get the header file for MQRFH2.
I have tried a lot and also fail to get.
Would anyone help me? really thanks a lot.

| Have the other side not put on the MQRFH2 header in the first place. You can search this site for targclient and you'll get detailed information on how to do it. |

There's a button on this page, under "Serving MQSeries Professionals Worldwide".
It's called "Search".
Click on it, and put "targclient" in the search string field.
Welcome to the Internet.

Dear jefflowrey,
I have done it. but still no found out. Would you mind to give me some more concept. I know MQRFH2 gets the header of StrucID, version, strulength, Encoding, codedcharsetid, format, flags and CCSID.
But i don't know how to read from VB.NET.
is that i use
readstring (4) for first 4 bytes of StructID. then
readLong () for the version.
but seem gets corruption for doing this.
Thanks |

If the sender changes their JMS Destination to use a target client of MQ...
Then there will be no MQRFH2 in the message.
So you won't have to read it.

Dear jefflowrey,
But the other side is written by vendor, so they will put the header on it.
They will not change anything, so i could only handle in VB.NET
Cheers |

If the RFH2 header is there (and you can't get the other side to 'remove' it), then you are going to have to a parse it out (probably using readbytes) to get to the real message payload. There is a description of the RFH2 header in the Application Programming Guide that gives you its layout.
However, I'd still suggest that you pursue its never being put on the message. I'm assuming that the other side is probably using JMSAdmin (or something similar) to create its destination. It is a very simple matter to specify you don't want the RFH2 header included. The targclient search mentioned earlier should give you dozens of hits on this. |

Instead of using VB.net use J# to wrap the java delivered classes by creating your own receiver. You will still be able to get at the message but now you can do it in JMS which will automatically strip the RFH header.
Nice thing is after writing your classes in Java to receive and extract the message you can invoke them from VB.NET.
Thanks for CLR
Enjoy  |

I only can use VB.NET to get the message. i can not use other jms problem to get the message first. sorry the only way is that i get the message from VB.net. Really headache on this.
Any function in MQ API that can convert the format?

Learn .NET!
You can use any langage supported in .NET
So write your classes in J# and instanciate from VB.NET !!
