passing queue to dynamically called VI

[Tushar_Jambhekar]

Hi Mike

Please look at how i wrote the code. please let me know if there is something wrong.

Actually if what if you are saying works out it will be better for me. In my application Dynamic VI is a reentrant VI and i launch several instances of that VI. and each instance has a different queue. if i have to follow the LV2G way then i will have to track all those queue refs. using array of refs.

but if your solution works then my work will get reduced.

thanks

Take a look at the VIs in my previous post. They are examples for named queues. Start, stop and close the VIs and observe the indicators.

There you are....

      Thanks for the valuable Queue tips!

Here's a [LV8.2] way to safely share a Queue with a spawned-process - retaining the advantage of strict data-type enforcement as well as the coding clarity that comes with explicitly-passed Queue reference, but without the dependency of specifying the same Queue name (and type) in multiple places.

Regarding complex hierarchies, I've noticed that many problems are avoided by not including a top-level VI.

Cheers!

Hi Tushar,

I feel the problem in your case will be without opening the front panel of the dynamic VI you are closing the refernce of the dynamic VI in the main panel. See attached code.
