Returns the unique identifier (UID) for the object. UIDs are identifiers for LabVIEW objects and are always unique within the same VI. Inspect the UID of an object to verify that it is the exact object that you want to manipulate.

A UID is always associated with the same object, even after you save the VI. However, if you delete an object, LabVIEW might assign the UID for that deleted object to a different object in the future. To detect this situation and ensure each UID refers to the object that you expect, check the Class Name property or Label property of the object in addition to the UID.
