event case with non-user action

[Yves]

Hi

I'm actually using LV8.0.1.
With this and older version of LV it wasn't possible to get an event case fired without an user action. (for example by changing the value programmatically.)

Is it possible in LV 8.2?

You can either use the Value (Signaling) property for any control (not including latched boolean) to fire Value Change events, or you can create your own events (search for the events palette and search the example finder) and register\unregister dynamically.

Hi tst,

thanks for your reply. Just tried to do it with the "Value Change Event".
BUT I must have missed something because it didn't worked.

What's wrong here?

Yves,

You just missed the property node in your right-most loop.  To create a property node, right click on the block diagram control->create->property node, and then select "Value(Signaling)".  Value(Signaling) is different from "Value" in that it "signals" to LabVIEW that a change has been made, and thus an event can fire.  See the image of the code in your right-hand loop.

Hope this helps!

Thanks for your help

If I'm right this should be the "good" version. Is there anything I have done wrong or should modify?
