I am using CPP classes Websphere MQ Client
Running on Windows XP
The Websphere Server is Running on Windows 2003 server
with the Queue having MaxMessageLength = 100
So whenever i send a message to the queue, it gets splitted into messages of size 100.
And while receiving such messages I am getting Chunks of size 100 of a single Message......then How can I Know which parts belong to the actual SINGLE message.....
Thanks... |

That's a very small max message length.... 
Look up the grouping and sequencing options in the APG.

I would have suggested looking into how to set the MAXMSGL on a queue.  |

Given the discrepancy between that value and the default, I would assume someone on site knows how to change it!

MORE INFO>>>
While receiving those messages I am getting the MQMD.MsgType as MQMT_DATAGRAM. I am cheching for MQMT_APPL_FIRST and MQMT_APPL_LAST but not getting these values.
Do I need to do some setting on the server for getting the "segmented messages"

No.
And what has message type to do with segmentation? Why (when these are clearly being sent as datagrams) would you get any application defined values? Which would not (or should not) be either of those 2 actual values which are intended to describe the range?
You either need to change max length as we suggested, or re-read the material on grouping & segmentation. As I suggested.
