| I need to invoke a single common Windows application based on the triggering of multiple message queues. Hence, I need to send in the name of the queue when trigger happens. I tried putting in the queue name to environment data or user data of the process definitions but I can’t seem to access this info in the Windows application. Can anyone please help me? Thanks. |

What have you tried and what happened ?
Is your application being triggered ? You should be passed an MQTMC2 structure to the triggered application, this structure contains the Queue Name.
Cheers,
Paul.

Whatever you put into the environment data and/or user data in a PROCESS definition is passed to your triggered application in the MQTMC2 structure.
Have a look at the amqsecha.c sample to see how it compares to your triggered application, or post some of your code here to show us how you are trying to access the data in question.
I would expect some snippets like this (in 'C'):-
| Code: |
MQTMC2 * trig; /* Trigger message structure */
:
trig = (MQTMC2 *)argv[1]; /* address the trigger message */
:
... trig->EnvData ... /* Use the Environment data */
:
... trig->UserData ... /* Use the User data */
|
Cheers,

You don't need to do this. The queue name is in the TMC structure, which appears as command line arguments on the triggered program. You will need to parse the arguments to get to queue name, qmgr name, userdata etc.
