How to deal with Type Descriptor when using Ctrl Val.Set in Invoke node

[wuweiwei]

Hello, I am weiwei and currently a beginner of LabVIEW.

I am now dealing with a sample program provided by IWATSU to apply on IWATSU DS-5624 oscilloscope.

However, the sample program itself I think is created by version 7.1 of LabVIEW. I face a problem that the invoke method "Ctrl Val.Set[Flattened]" is shown to be deprecated and it told me to switch to "Control Value:Set" instead.

  When I switched to "Control Value:Set", the options of "Type descriptor" and "Flatten data" disappeared and "Value" appeared. I don't know how to deal with the type descriptor if I connect the flat data(string) to the option of "Value".

  I will attach the screenshot and the whole file in this article. Please check it if you need.

The file is the Viewgo_Remote_Sample(Visa)(Ver3.02).vi inside the zip file. I apologize if some program written in Japanese cannot be shown properly since the manufacturer only provided this sample program in Japanese.

Hi,

Try using "Flattened String To Variant" to convert Type String and Data String to a Variant:

Hi Raphaël,

Thank you for your advice. I will try to apply that later.
