You are attempting to reference an object that is no longer valid or has not been set.

Possible causes:

  • The object has been closed.

  • The object has been orphaned (the parent object has been closed or deleted).

  • The object is out of scope.

  • The object library is not registered in the Microsoft Windows Registry.

  • You are trying to reference a method or property of the collection, but you have not assigned it to a variable first. For example, to reference the Name property, use the following:

  Dim dbsPublish As Database 
Set dbsPublish = OpenDatabase("BIBLIO.mdb")
dbname = dbsPublish.Name
