I'd like to use the live feature in QMH. Please help me.

Hello everyone,
I've recently started learning about Labview development. I'm trying to create a live feature using the QMH (Queue-Message-Handler) architecture, but I'm facing an issue where it only runs once. In this loop, when I trigger the "live" event, I want it to keep executing infinitely within that while loop. How can I achieve this?
Thank you.

Hi Rong,

When you want to call the "Live" case repeatedly you need to call it more than once…

Have you tried to "re-trigger" that case by sending the message more often?

 

Btw. why are there so many wire bends in your image?

And I would recommend NOT to use "default if unwired" tunnels for references!

Best regards,
GerdW

I appreciate your response.

I initially attempted to use the live feature to receive real-time data from the camera and display it like a live stream. While triggering it multiple times would show the next frame as if it were "captured," it didn't provide the live functionality I desired.

As a result, I changed the functionality as shown in the image below. However, this isn't what I'm looking for; I'm interested in enabling/disabling live functionality using a queue.

I'm unsure about the meaning of "unconnected default tunnel." I'm learning LabVIEW, but I don't have a mentor to guide me.

Thank you for your assistance.
