The IsBroken property returns a Boolean value indicating whether a Reference object points to a valid reference in the Windows Registry.
Setting
The IsBroken property is available only by using Visual Basic and is read-only.
The default value of the IsBroken property is False (0). The IsBroken property returns True (–1) only if the Reference object no longer points to a valid reference in the Registry.
Remarks
By evaluating the IsBroken property, you can determine whether or not the file associated with a particular Reference object has been moved to a different directory or deleted.
If the IsBroken property is True, Microsoft Access generates an error when you try to read the Name or FullPath properties.
