Variant To Data

Converts variant data to a LabVIEW data type so LabVIEW can display or process the data. Some applications provide ActiveX data in the form of a self-describing data type called a variant. This ActiveX data is available on the block diagram as a LabVIEW variant. To review or process the data in LabVIEW, you must convert it to a corresponding LabVIEW data type using this function.

type is the LabVIEW data type to which you want to convert the variant data. type can be of any data type, however if the data must be able to conform to the data type. For example, if the data consists of letters, you must wire a string to type. Otherwise, no data is retrieved. However, if the data are integers, you can coerce the data to another numeric representation, such as an extended-precision floating-point number. Valid LabVIEW data types for variant data include numeric, Boolean, string, or refnum data types, or arrays or clusters of those data types.
Variant is the variant data you want to convert to the LabVIEW data type specified in type.
error in describes error conditions that occur before this VI or function runs. The default is no error. If an error occurred before this VI or function runs, the VI or function passes the error in value to error out. This VI or function runs normally only if no error occurs before this VI or function runs. If an error occurs while this VI or function runs, it runs normally and sets its own error status in error out. Use the Simple Error Handler or General Error Handler VIs to display the description of the error code. Use error in and error out to check errors and to specify execution order by wiring error out from one node to error in of the next node.
status is TRUE (X) if an error occurred before this VI or function ran or FALSE (checkmark) to indicate a warning or that no error occurred before this VI or function ran. The default is FALSE.
code is the error or warning code. The default is 0. If status is TRUE, code is a non-zero error code. If status is FALSE, code is 0 or a warning code.
source describes the origin of the error or warning and is, in most cases, the name of the VI or function that produced the error or warning. The default is an empty string.
data is the resulting LabVIEW data type. If empty, the data could not be converted to the data type specified in type.
error out contains error information. If error in indicates that an error occurred before this VI or function ran, error out contains the same error information. Otherwise, it describes the error status that this VI or function produces. Right-click the error out indicator on the front panel and select Explain Error from the shortcut menu for more information about the error.
status is TRUE (X) if an error occurred or FALSE (checkmark) to indicate a warning or that no error occurred.
code is the error or warning code. If status is TRUE, code is a non-zero error code. If status is FALSE, code is 0 or a warning code.
