How can a block/freeze a ring or enum control element when I Boolean signal is set?

[larsfrese]

Hello! I am still a starter with LabView (working with 6.1).

On the Front Panel of my VI the operator can use a ring control element to choose some (6) options. I am searching a way to block the scroll down menu of this ring element when a Boolean Signal is set. Only when this Boolean Signal is false, my operator should have the possibility to chance the ring or enum element.

Is this possible?

Hopefully

Lars

Hello Lars,

have you tried a property node "Disabled" for your ring/enum? See the help for this property!

[larsfrese]

Yes I have and there is amongst others a point called “disabling ring control items”, but it only shows me a way to de/activate the ring item by mouse, but not by an internal signal. I also searched my library.

I am using a German LabView Version and a lot of help documents are not available.

What Gerd meant was that you need to create a property node. Right click on the control or the terminal and select Create>>Property Node. Then, select the Disabled property, right click it and change to write and set the value you want (0, 1 or 2). You can change the boolean to a number by using Boolean to 0:1 from the Boolean palette. This property is common to all controls, not just rings.

To learn more about LabVIEW, I suggest you try searching this site and google for LabVIEW tutorials. Here and here are a couple you can start with. You can also contact your local NI office and join one of their courses.
In addition, I suggest you read the LabVIEW style guide and the LabVIEW user manual (Help>>Search the LabVIEW Bookshelf).
