events in events

[asalles]

    Hi everybody,

Maybe this problem has been answered before but I couldn't find the topic
Here's my problem:
I'd like to control an event in an other event structure.

To now, the only result I get is that all my front panel is frozen.

It's certainly normal behaviour but i'd like to have confirmation.

Thanks for help

Have a nice day !!

Hi asalles,

you know you should only have ONE event structure in your vi? And you can have more than one event per event structure?

Could you describe in more detail what you mean by "control an event"? Can you attach an example of your vi?

[parthabe]

Maybe you can try unchecking the Lock Ffront Panel option in the Edit Events dialog box.

Moreover using 2 ES in the same VI is not advisible.

Read the Caveats & Recommendations in using the Event Structures before you code with them.

[parthabe]

See to the point highlighted in Red. This is what GerdW implied, I think...

I also meant this only.

This is available in the LV online help. Just read them, you ll understand more about them.

[Wiebe@CARYA]

What do you mean with "control an event"? Trigger another event, or read
another event?

The first can be done with Value (signalling) or with user events.

The second has to be done with user events. Nesting event structures will
never work, and even putting two event structures in one vi is not supported
(but will work sometimes).

Wiebe.

Thanks all,
It's working now
parthabe's advice was right

It is necessary to uncheck "Lock front panel until the events case for this event completes"

please find the vi I realized.... it  will more clear for you.

Next step will be to use subVIs

Thanks

Hi asalles,

I changed your vi to use only one event structure.
I also changed all the events to "value changed" and moved the terminals into the event structure (the values should be read somewhere&somewhen!)...

[parthabe]

You must avoid using nested ES. It is NOT AT ALL NEEDED.

All you need is this, see the attached VI.

[parthabe]

But GerdW,

I observed one thing in his nested ES VI.

How many times you click on the Activate bool, that many times the Generate bool can also be clicked to generate a random number. Only after that many clicks, it gets invisible again.

It is like a 1-1, 2-2 & 3-3 times scenario.

Maybe a bit more modifications are required if that is the desired functionality.

Hi Partha,

I would prefer the non-chattering behaviour of a switch. For me it doesn't make sense to click "activate" more than once when the "get value" is still visible...

Well, in the end we need more specifications from asalles to decide on this! (As usual: you need a well-defined problem to write software for it...)
