Initializing Variant Constants in LabVIEW

Issue Details

How do I set the initial value of a variant constant in LabVIEW? Can I initialize it the same way I initialize a String or Numeric constant?

Solution

The LabVIEW Variant is a unique data type designed to serve as a generic container for all other data types in LabVIEW. Initializing a variant in the block diagram essentially involves converting another LabVIEW data type constant into a variant using the ‘To Variant’ function, as shown here.

You cannot manually type a value for a variant, just like you do with String and Numeric.
