ACC2000: VBA Functions Break in Database with Missing References

Moderate: Requires basic macro, coding, and interoperability skills.

This article applies to a Microsoft Access database (.mdb) and to a Microsoft Access project (.adp).

For a Microsoft Access 97 version of this article, see 160870 .

For a Microsoft Access 2002 version of this article, see 283806 .


If you have a procedure that contains a Visual Basic for Applications function, and your database contains a reference to a missing object library or type library, you may receive the following error message when you compile your modules or run the procedure:
Compile Error:
Can't find project or library


Your database contains a reference to a database, type library, or object library that is marked as MISSING: <referencename> in the References dialog box.


To remove the missing reference, follow these steps:

  1. Open your database.
  2. Press ALT+F11 to switch to the Visual Basic Editor.
  3. Open a module in Design view.
  4. On the Tools menu, click References.
  5. Click to clear the check box for the type library or object library marked as MISSING: <referencename>.
An alternative to removing the reference is to restore the referenced file to the path specified in the References dialog box. If the referenced file is in a new location, clear the MISSING: <referencename> reference and create a new reference to the file in its new folder.

NOTE: In an Access run-time application, you cannot view references from a menu. However, the following article demonstrates how to view references by using code:
