Labview Variant Data Type

For example, if you convert string data to a variant, the variant stores the text of the string as well as information indicating that the data was converted from a string (not a path, byte array, or other LabVIEW data type).

      Use the Variant functions to create and manipulate variant data. You can convert flattened data and LabVIEW data to variant data and vice versa.

Variant data types can store data attributes. Attributes are information about the data that is defined and stored by the variant data type.

　　For example, if you need to know the creation time of a certain data, you can store the data as variant data and add an attribute - time, which is used to store the time string. Attribute data can be of any data type. You can also delete or get attributes from variant data.
