Use the Variant VIs and functions to add, retrieve, and delete attributes in LabVIEW variants, manipulate variants, and retrieve data types of variants.

To Variant Function
Converts any LabVIEW data to variant data. You also can use this function to convert ActiveX data to variant data.
Variant To Data Function
Converts variant data to a LabVIEW data type so LabVIEW can display or process the data. You also can use this function to convert variant data to ActiveX data.
Variant Constant
Use the variant constant to pass an empty variant to the block diagram. You cannot set a value for the variant constant.
Flattened String To Variant Function
Converts flattened data into variant data.
Variant To Flattened String Function
Converts variant data into a flattened string and an array of integers that represent the data type. You cannot flatten ActiveX variant data.
Get Variant Attribute Function
Retrieves the names and values of all attributes or the value of a single attribute, depending on whether you wire the name parameter.
Set Variant Attribute Function
Allows you to change or create an attribute and value for variant data.
Delete Variant Attribute Function
Deletes an attribute(s) and value(s) in variant data.
Data Type Parsing
Use the Data Type Parsing VIs to retrieve and compare the data type stored in a variant to other data types.
