How to set/get the "attribute" of a control from a subvi

[John Cruz]

Labview 5.1.1
WinNT 4.0

Hello.

I'm trying to figure out how to retrieve and most importantly, set the
attributes of a control from subvi. I remember seeing one post that says
use the invoke node but all I could find close enough is the set/get control
values (not attributes).

Could anyone point me how to solve this?

TIA

You use the set value node to set a control of your top level VI. On the
diagram, this control set the attribute node.

thanks for the fast response BUT....

are you referring to Invoke Node->Method->"Set Control Value" ? It only
sets the value of the control (hence the name) and not the attribute. If
your not referring to that... could you point me out to where I can find
that node?

TIA,

John

No, there is no direct way to set the attribute node from a SubVI. If you
want to set the attribute of ControlA from outside its VI, you need another
control ControlB that is wired to that attribute of ControlA on the diagram.
from a subVI or anywhere else, you use a Set Conrol Value node to ControlB
to sets its value. Set Control Value is only one method to pass data from
one VI to another. You could use other methods like globals or notifiers to
pass the attibute value to the node.

I didn't think of that one before (using another control/indicator to
control the attributes from a subvi)... nice idea!

Thanks alot.
