Ring control behaviour

[andre@carya]

Hello all,

Two questions...

I noticed a big difference in handling the ring control in LV (5, 6 and 6.1)
and (7).

The difference is in what is displayed as the ring selector value is "-1".

In LV (5, 6, 6.1) it is the last string in the string array.
In LV(7) it is "<65535>".

First question:

Is it possible to get the LV (5,6, 6.1) respons in LV (7), because the are a
lot (and I mean a lot) of ring controls used in the application.

Second question:

Why is it changed?

Pop-up on the ring control and look at the Representation. You'll notice that in some versions of LabVIEW it's an I16 and in others it's a U16. You can change the representation to an I16 and then -1 is a valid number for the ring (instead of just a wrap-around).

And, no, I don't know why they changed the default.

This change hit me hard as well.

In my case there only about 6.

While you a "poping up" as Rob sugested, go to the properties.
On the "edit Items" tab, un-select the sequetial items box and then enter "-1" (aka 65535) and leave the string as blank.

It will work the same way at it did in 6.1.

Now if we could only do this for enum's....
