This feature will be removed in a future version of Microsoft SQL Server. Avoid using this feature in new development work, and plan to modify applications that currently use this feature.
The Set property returns TRUE if the referenced object property is changeable.
If TRUE, the property referenced is read/write or write-only. However, an application attempt to change the property value is not guaranteed to succeed. Constraints for the referenced object property, such as properties that can only be set prior to Microsoft SQL Server component creation, can cause a property change to fail.
If FALSE, the property referenced is read-only.
