How to generate a event in by code in vi

[MViControl]

Hello,

I am thinking to generate a event by code in a vi.

e.g.

I have a button in vi and I add a "value change" event for it, how can I triger the event by G language in a vi without click the button in front panel?

can anybody share the experience?

Create a property node for the button and use the Value (signaling) property - note that this won't work on booleans with latching behavior

You can also use User Events to fire the same event programatically, though that requires a little more supporting framework. Or, if your events correctly issue messages to parallel loops, you can achieve the effect of firing the event by simply sending the command directly to the parallel loop.

Thanks,

the purpose of thinking this is to reuse the code in the event case created before. e.g. I have created code for a button "value change" event, while in other place of vi, I want to programatically fire the event to excute the code in the event.

mesmith and Daklu,

do you have some simple examples to achive this?

Here are examples of both methods. Of course, in your real program you would want to make sure you do proper error handling and disposal of user events using "Destroy User Event"

Sorry, those were in LV 2009. Here they are in LV 8.6 if needed.

Trigger Event - Value Signaling.vi

Trigger Event - User Events.vi

Trigger Event - Value Signaling_LV86.vi

Trigger Event - User Events_LV86.vi
