how to exit from button callback function before it complete execution in LabwindowsCVI

Idle events aren't so much deprecated as they're obsolete. In the sense that, once timer controls were introduced, idle events lost their reason for being. But they're not going anywhere, so it's okay to use them if you find them more convenient.

I couldn't resist a back-to-back comparison of the two approaches. The TIMER version managed 423 scans in 8.79 secs at 34% CPU usage. The IDLE version did 399 scans in 8.76s at 8%. I'm staying IDLE 🙂

I was to ask Luis some hint on when and why to use idle events instead of timers.

Seems your tests give me an answer

I assume I have to deep my knowledge on idle events

I would test both approaches on a loaded CPU, you may have some surprise... message queues *usually* are not happy with busy systems...
