Obtain Queue --> Release Queue

[DonRoth]

Is it true that, for a particular named queue, every time one uses the 'Obtain Queue' fx, you need to call the 'Release Queue" Fx?

I was under the impression that, unlike programmatically-generated references, the 'Release Queue' fx for a particular queue only needed to be called once, when completely finished using the queue (such as in an exit case when shutting down the program).

The LabVIEW help for 'Obtain Queue' does not indicate this situation.

This is true, unless you create a boolean "True" on the 'Force Destroy' terminal of the Release Queue. If you do, the queue reference will be closed and any remaining calls to that queue reference will not work and generate errors.

Yes, now I do see this in the Labview help for the 'Release Queue' fx and in fact this was the strategy I was using (setting 'Force Destroy' to 'True'). Probably an annotation on this in the 'Obtain Queue' fx help would be useful.

There is an interesting article about this topic in the latest (Volume 11, Number 4) LabVIEW Technical Resource.

Its title is : Did you know that the behavior of the queue and notifier functions has changed with LabVIEW 6.1 and 7 ?
