Hello everyone,
I have a quick question. I have a MQClient application which connects to a Server and puts messages using MQPUT. How do I get the MQ Message ID for the message just put using MQPUT?
Any help on this will be greatly appreciated.
Thanks in advance!!!

After your MQPut call, message descriptor is returned back to you with generated values for few fields. You could refer to the same in your code following MQPUT call. For example,
| Code: |
MQMD md = {MQMD_DEFAULT};
...
MQPUT(Hcon, /* connection handle */
Hobj, /* object handle */
&md, /* message descriptor */
&pmo, /* default options (datagram) */
count, /* message length */
buffer, /* message buffer */
&CompCode, /* completion code */
&Reason); /* reason code */
|
Use md.MsgId to refer to generated MsgID....

The specifics depend of course upon which programming language you are using, but the MQI API always provides a way for accessing the MsgId after an MQPUT. This is usually accomplished by probing the same variable/object that you would have populated with a number had you wished to create the MsgId yourself. Kirani is showing the correct way to retrieve this value with C, and like I said, the process is similar in most other languages...
