I am trying to implement a wait into my get from a queue.
I implemented the following code and received a MQRC_OPTIONS_ERROR. My question is what is the difference between WaitInterval and MQGMO_WAIT; if they need to be used together; or if they work independently. I am currently just setting the WaitInterval, and I don't seem to be getting any errors, however, I also don't know if it is doing anything!! This is written in VB running on Win 2000.
oMsgOptions.WaitInterval = 100
oMsgOptions.Options = oMsgOptions.Options & MQAX200.MQ.MQGMO_FAIL_IF_QUIESCING & MQAX200.MQ.MQGMO_SYNCPOINT & MQAX200.MQ.MQGMO_WAIT
GetMQQueue.Get oMsg, oMsgOptions

MQGMO_WAIT and wait_interval work in conjunction. On a get you need to first say that i want to wait for a message, which is what MQGMO_WAIT is. And then you need to specify how long you want to wait, which is wait_interval.
As for why you are getting 2046.
Are you getting this on a Get, open or from which api call???
If on the get, what is the value of oMsgOptions.Options before you add MQGMO_WAIT and other stuff on it.
Cheers.

The only options are what I set and posted which is:MQAX200.MQ.MQGMO_FAIL_IF_QUIESCING & MQAX200.MQ.MQGMO_SYNCPOINT
Would any of these cause an issue with WAIT?

| Code: |
| oMsgOptions.Options = oMsgOptions.Options & MQAX200.MQ.MQGMO_FAIL_IF_QUIESCING & MQAX200.MQ.MQGMO_SYNCPOINT & MQAX200.MQ.MQGMO_WAIT |
If I remember well VB, the operator "&" is used for concatenation, not for logical expressions. You should use "or" or "+" to get a correct result.
Also, you are combining the options with a previous value of the variable, are you sure of the previous value of the variable?
