PropertyObject.LockTypeDefinition

Syntax

PropertyObject.LockTypeDefinition

Purpose

Changes the in-memory state of a password-protected type definition to locked. This method returns an error if you call it on a type that is not password-protected.

Remarks

You can call this method on any property of the type definition, not just the root object of the type.

Note TestStand supports password-protecting type definitions to deter unauthorized users from editing the types in the sequence editor. However, any TestStand user can continue to programmatically edit a locked type by using the TestStand PropertyObject API. National Instruments does not recommend password-protecting types as the only way of protecting intellectual property.
