Re : Re: Linking VI and a Sub VI

[Basile21]

Hi everybody,

How can I send data from the VI to the sub VI without a direct link with a think like a property node or some think like this.

Hi Basile21,

you can use queues or notifier. Can you explain what you need? You can also be flexible with using property nodes.

Use the Set Control Value method, if you have a VI reference. If you have a
control reference, use the value or value (signalling) property.

It's not very decent programming to do this. It's better to use a buffer
vi/smart global/lv2 style global/action engine.

What are you trying to do?

Regards,

Wiebe.

Hi Wiebe,

I have a VI in wich I have a Sub VI in wich I have a waveform chart and my purpose is to delete the graph at each run of this VI.

Thanks for your help.

Hi Basile21,
in this case you can simply delete the graph in the subvi. Clear the graph before you do something else.

Hi Mike,

Thanks, but I want to reset the graph automaticly before each run.

Hi Basile21,

yes, i understood it. So insert the delete function in your vi, before some other code.

I don't know if this is your case, but i clear the graphs ant indicators at the end of the vi. So the next time it is called, it is ready.

Hi Pnt,

Yes it's what I want to do, can you tell me how you do it please.

Thanks for your help

the simple way. Wire an empty array to it.
