Trigger Menu via Events/Boolean

[winterishere8]

All

I have a custom run-time menu. One of the menu selection which performs task (A) is done through Event structure. I want to repeat (A) everytime I complete a task. Currently what I have done is replicate (A) into another event and use boolean value signalling.

Is there any way to programmatically trigger the menu event so I don't need to replicate (A) ?

Thanks

You don't have to replicate (A) if you trigger the boolean in the menu selection as well. So, if the menu item is chosen, change the boolean just like after a task.


Instead of using a boolean, you could use user events.


The code will be much cleaner then programmatically triggering the menu.

Is there an example that you can point me to ? I am still not very clear on how to implement this ?

Thanks

Perhaps I'm misunderstanding the requirements, but why not just put the behavior you want duplicated in a SubVI and call it from the menu handling case as well as wherever you finish the "tasks" you are doing?  While there are certainly ways to hack at event/event-structure usage to make this work, it seems like an unnecessary level of complexity.

Hello Jason

That's similar to what I am doing now except that the behavior is not embedded in a subVI. I am just tryin to see if I can use properties like boolean value signalling to trigger menu events programmatically.

Thanks

Nope, no way to programmatically trigger menu selection events in LabVIEW.  Given what you've said (and obviously not having seen your application) I think moving the code you want to "reuse" into a SubVI and just calling it from multiple places is the best bet.  While using the event structure as you describe can be quite powerful, I don't think it's a very elegant solution in this case.

You don't have to trigger the menu. Put the code you want to execute in the boolean value change event. If a task ends, send a value change (signalling). If the menu is selected, also send a value change (signalling).


There are shell activex objects that can trigger menu's. Please don't use them for this!

Thanks Wiebe. That worked. Simple and easy solution.
