At my top level VI I have some simple button controls. I'd like to pass those controls to subVI so that the subVI can read and react to changes in the button states.
I tried using a control reference.
First I created a new subVI. Placed a refnum (control) on the front panel. I then inserted the type of boolean control that would be passed and wired it to the connection for the subVI. Then I tried to wire some dataflow in the subVI to read this control and ran into problems.
I created a property node to read the control, but the "Value" property appears to be the actual value of the refnum, not the value of the control itself? Is there a way to read the value of the control, or can I only read/modif
y its position, color, etc and not its actual value?
