  • iaprn.png reference out —
    reference out returns reference unchanged.

    error out contains error information. This output provides standard error out functionality.

    • If the property you want to write is variant, you can wire LabVIEW data and it automatically converts to variant data indicated by a coercion dot. ActiveX does not support 64-bit integer data types. If you wire 64-bit integer data to a variant parameter of an ActiveX Property Node, LabVIEW converts the data to a double-precision, floating-point number. If the property is variant, use the Variant To Data function to convert to LabVIEW data, if needed. If you right-click the Property Node and select Select Class»ActiveX»Browse from the shortcut menu, LabVIEW displays the Select Object From Type Library dialog box.

    On the front panel or block diagram, right-click an ActiveX object, select Create»Property Node, and select a property from the shortcut menu to set a property for the object. You also can select ActiveX-specific properties for an ActiveX object. On the block diagram, right-click an ActiveX object, select Create»Property Node, and select an ActiveX-specific property from the shortcut menu.
