This article was previously published under Q130646 SYMPTOMS
A reference to any database object or method in a Visual Basic program
generates the error:
User-defined type not defined
This error often occurs when loading your first Visual Basic version 3.0
program into Visual Basic version 4.0.
CAUSE
When you load your first Visual Basic version 3.0 project, a dialog box
asks you:
Would you like Visual Basic to add this library reference now?
If you selected the "No for All Older Projects" button, an entry was made
in your VB.INI file that says AutoReferenceDAO=1. If you remove this line,
you will see the dialog box again and be able to add needed Visual Basic
3.0 project references automatically.
RESOLUTION
For the current project, choose References from the Tools menu, and select
the Microsoft DAO 2.5/3.0 Compatiblity Library check box. This enables
compatibility with the older syntax found in Visual Basic version 3.0
programs. Microsoft reccommends that you upgrade the syntax in your
programs to the new DAO 3.0 syntax used in Visual Basic version 4.0,
replacing the DAO 2.5/3.0 with the DAO 3.0.
STATUS
This behavior is by design.
