Update HMI VI while looping another VI

[MartialWasTaken]

Good afternoon,

I'm trying to separate a VI in two parts : one doing a long process, the other showing gradually to the user the results of this process but I want to let the user cancel the process at any time. How can I do this ? I tried to call the HMI VI with an event structure IN but it's blocking the process. I also looked to do an asynchronous call but it doesn't helped me that much.

Knowing the interface is extremely simple and won't do complex tasks, it look like this :

Thank you in advance for your attention.

Hi Martial,

learn about using queues and notifier (or wire channels), then place "process" and "HMI" into their own loops…

I would like to also add User Events to this list.  I use User Events to pass data from the process loops to the HMI loop (which is mostly an Event Structure already).
