Newbee Question: How do I connect a combo box selection to the output terminal?

[dk-info]

I want to use a Combo Box in a VI to select from a list of strings to direct execution in TestStand.

• How do I connect the selected string in the combo box to the output terminal of the VI so I can see it in TestStand?
• What do I use as the "value" in TestStand module parameter to retreive the result of this VI?

I tried "wiring" the result of the combo box directly to an output terminal without sucess.

I tried "wiring" the output of the combo box to a string variable; wiring that variable to an output terminal without success.

(see attached files)

Can anyone give me an example of a VI that will select from a list of strings: {"Bob", "Mary", "Bill", "Jennifer",...} using a

combo box (or similar) control and routing the selected string to the output terminal? 

Thanks in advance for suffering through this fundamental question.

Like this? Download both, and run the RunMe.vi

I can't see the suggested code since it's in LabVIEW 2012, but if you're using a Combo box, then you can simply pass out the value of the combo box directly to a string indicator. No hoops needed.

If this is what is shown in the suggest code, then ignore this response.

Thank you for the reply, what is the name of the string passed to TestStand? I am trying Step.Result.Status (the vi used is a generic "action" step) and it does not seem to work.

By "Selected string" I assume you mean the string displayed to the user rather than the value of the combo box.  I would not use a combo box in this case. I would use a type defined enum instead.  TestStand will display the string but uses the integer value for calculations and expressions.

Of course it does not work. Status is a boolean. Did you create a TestStand string variable that you want to use?

There is a Using LabVIRW With TestStand document that you should review.
