Creates a control or constant of the data type you specify. LabVIEW always creates a control initially, even if you configure Style to create a constant or indicator. To change the type of the new object, use the Indicator property.

Use the To More Specific Class function to try to cast the reference this method returns to the specific class you want to use in the application. If the function does not return an error, the reference matches the specific class.


Data type Name Required Description
LV Variant Data Type Yes The data type you want to use to create the constant.
I32 Style Yes Specifies whether you create a front panel or block diagram object. If you select a front panel object, this parameter further specifies the style of that object.
Numeric Cluster Position No Specifies the position where you want to create the constant or control.
Control Refnum New Object Reference No The reference to the constant or control you create.
Boolean Make Names Unique (F) No



Version Change(s)
LabVIEW 2011 In LabVIEW 2011 the Create from Data Type method changed the data type of the Style parameter from a 32-bit signed integer to an enum. The Style parameter also includes the following new values: {Probe, Diagram, Panel Control, 3D Panel Control, Dialog Panel Control, Panel Indicator, 3D Panel Indicator, Dialog Panel Indicator, Power PC Control, and Power PC Indicator.} (For the new method see the Create from Data Type method.)
