Saving Custom Controls

Three options:

- Custom Control

Custom Controls & Type Definitions

Control No connection

between the one yousaved and theinstance in the VI

Update the file, butthe instances are notupdated

Type Def Connection between the

saved file and allinstances

Forces the data type of

each instance to beidentical (clusters, enum)

Changes made to file willpopulate throughouteach instance

Strict Type DefConnection between

saved file and all

instances

Forces everythingabout

an instance to be identical

to the strict type

definition, except:
