queue can not popup dialog program or VI

[Billy.Deng]

hello everybody,

          I program this , push "E" key, but not see popup  VI or dialog program. Who can help me to analyse and solute it ? thank you .....

What's in your 0 case? Can you post the vi?

What is this VI supposed to do?  If you never put anything into the queue, then you'll never be able to get anything out of it, and I don't see an enqueue anywhere (although with a named queue you could have one somewhere else that you're not showing us).

[SteveChandler]

He is enqueueing a '0' just after obtaining the queue. But we need to see what is in that case or better yet the whole vi and the subvi that is shown in the selected case.

[Billy.Deng]

    now, give the queue "0", sub vi only has one while loop, not any thing.

my mind is when I push "E","F","G","0" key can open their sub vi, but debug only can see sub vi is running, however , can not see dialog box, why?

Which dialog box?  As previously suggested, it would help if you attach your VIs.  Without that we have no idea what you're trying to do.

Is your subVI a dialog box?  You may need to open VI Properties, go to the Window Appearance page, click Customize, and set the option for "Show Front Panel when Called."

thank you so much, i forgot to set up vi per, yes it is that.when i adjust it can show sub vi running.
