Input items to a ComboBox at runtime

[TDSquare]

Hi

I'm trying to use a comboBox to display a list of item only at runtime. For example, there are 2 combo boxes, the first one is a menu (1-4), when option 1 is selected at runtime, the second combo box should have a list for option 1 which might be (A-D). It this possible in LabView 8?

Sorry it's in LV 7.1.1, but it should work in LV 8 also 😉

Please see attached for your reference.

In addition, you may consider using

1. Enum or
2. Menu Ring

to achieve your requirement 😉

Cheers!

Cool, i tried both solutions. I'm deploying it to a PDA, so the same rules should apply right?

[TDSquare]

might i'll try both solutions. Thanks for the quick response

I forgot to mention that it is for a PDA, so property node is not supported.

Any other ideas?

Plus, the String ComboBox has a very small drop down button that the size can not be increased and it can't be see on a PDA, a Ring drop down will be prepared.

Well the code is not different to do the same with a dropdown box instead of the combo.

I have never used LV on a PDA and didn't know that property nodes are not supported .... an then I don't know how to do that...
Sorry...

In LV PDA 7.1 there is a function in the Application palette: PDA Set Ring Strings.vi. It needs a reference to the ring control as input.
However, there were many changes from 7 to 8, so I don't know if it's still there.

Hi

The PDA Set Ring Strings.vi is still available on the Applications Palettein LabVIEW 8 for your reference.
