control the visibility from multiples vi's

[Haroldo-Itap-Br]

I need to control the visibility ('visible' property) of 3 controls (one flag and two intergers) from multiples vi's. Does anybody have a pratical example how to do it?

Hi Haroldo,

use references as in attached example...

Thank you for your promtly reply but I forgot to say that my LabView is 7.0 so was not possilble to open it.

Hi Haroldo,

I would suggest to put this info into your signature, so you will never forget to mention this

Thank you again for your patience!

Yes, the visibility of the controls works but I can not say the same about the value of it, I mean, I was not able to modify their values to make then usable for other VIs. I tried by including the 'value property' but the wire became a 'variant' and I can not void that.

Could you please go a bit futher with another tip?

Rgds,

Hi Haroldo,

this problem arises because of building an array of references from different types of controls (regarding datatype). You have to work with variant OR you have to convert the reference for each control "to more specific class" (found in application control palette). Then you can wire the correct datatype to the value property node...

Like we say around here: goool!

I took the "to more specific class" way.

Many Thanks!
