XL2000: You Receive "User-Defined Type Not Defined" Error Message When Using Data Access Objects

When you run a Microsoft Visual Basic for Applications subroutine using data access objects (DAOs), you may receive one of the following compile error messages:

You may receive the error message when a subroutine contains code that uses the Microsoft DAO Object Library, and the library is not referenced.

To avoid the error message, follow these steps:

1. In the Visual Basic Editor, click References on the Tools menu.
2. In the References dialog box, under Available References, select Microsoft DAO 3.5 Object Library, and then click OK.
   
   If Microsoft DAO 3.5 Object Library is not listed in the list box under Available References, click Browse, and then navigate to the Dao350.dll file. It should be found in the following location:
   \Program Files\Common Files\Microsoft Shared\Dao\Dao350.dll
   Select the file, and then click OK. This returns you to the References dialog box. Click OK.

When you run a subroutine using DAO, and the DAO Object Library is not referenced, you receive one of the messages listed in the "Symptoms" section, depending on what code is written. If your code declares variables, for example you receive the error message, and the subroutine fails in the variable declaration section.

If you did not declare your variables, you receive the following error message and the subroutine fails at the first use of a statement that requires the DAO Object Library. This line is usually: In this case, the subroutine fails when it encounters the "Workspaces" term.
