Get Property Values VI

Owning Palette: DataFinder Toolkit

Requires: LabVIEW DataFinder Toolkit

Determines from the result references the values of one or more properties that are the same data type. To select the polymorphic instance, connect data to the Data Type input or to the Property input or select the instance manually.

In the following table you see how the Get Property Values VI converts different data types of the search results. If a cell contains an x, the data can be converted. If a cell has a hyphen (-), the conversion produces an empty value. The Toolkit then displays a warning.

Data Type	-> String	-> Double	-> Time Stamp
String	X	-	-
Double	X	X	-
Path	X	-	-
Time Stamp	-	X	X

Note   When you convert a Double value into a String, the decimal separator is always a point. When you convert a Time Stamp into a Double value, the Toolkit calculates the seconds since 01/01/0000 00:00:00 local time.

Get Property Values (String Properties)

	data type specifies which data type the property values are returned in.
	properties specifies the object type, the name and the data type of the property. object type Enumeration for the object type. {File:0, Channel Group:1, Channel:2} property name specifies the property. data type Data type of a property indexed by the DataFinder. {String:23, Int32:3,Double:10,Time stamp:30, Unknown:0}
	result references are the result references from which the VI takes the property values.
	error in (no error) describes error conditions that occur before this node runs. This input provides standard error in functionality.
