From the Project Explorer window, right-click the LabVIEW class and select New»VI for Override from the shortcut menu to display this dialog box. Use the New Override dialog box to select an ancestor dynamic dispatch member VI to override. A dynamic dispatch member VI can override, or extend, the functionality of an ancestor dynamic dispatch member VI. LabVIEW dims the New»VI for Override option if the class you select does not inherit member VIs that are available for you to override. The VIs in the ancestor class must be dynamic dispatch member VIs in order for you to override them.

This dialog box includes the following components:

• Select a Method To Override—Displays ancestor methods available to override.

Note  A member VI can override a member VI from a parent class only if the following setting are the same for both VIs: reentrant settings preferred execution settings priority settings access scope connector pane terminal connector pane pattern

LabVIEW uses the ancestor VI icon and overlays the icon mask of the child class to create the icon of the new VI.
