XL97: Run-Time Error Using CreateObject With DAO.DBEngine

ID: Q157471

The information in this article applies to:

SYMPTOMS

When you use CreateObject in a Microsoft Excel 97 macro to use Data Access Objects (DAO), you may receive the following error:

Run-time error '429':
ActiveX component can't create object


CAUSE

If DAO 3.0 is not installed and you use the following line of code: 


   Set x = CreateObject("DAO.DBEngine")
you will receive the error message described in the "Symptoms" section.

NOTE: This line of code will successfully create, without error, a DAO 3.0 object if DAO 3.0 is installed on your computer.


RESOLUTION

With DAO 3.0, the object name is "DAO.DBEngine" and with DAO 3.5, the version provided with Microsoft Excel 97, the object name has changed to "DAO.DBEngine.35". So, if you have DAO 3.5 installed, the following line of code will create, without error, a DAO 3.5 object: 


   Set x = CreateObject("DAO.DBEngine.35")
Since the object names for DAO 3.0 and DAO 3.5 are different, it is recommended that you avoid using CreateObject altogether with DAO for your code to be compatible with both versions of DAO.

Instead of using CreateObject to use DAO in your macro, check the appropriate Data Access Object Library in the References dialog box:

  1. With a module sheet active, click References on the Tools menu.


  2. Check the "Microsoft DAO <x.x> Object Library" (where <x.x> is the DAO version) and click OK.

Follow these steps to run a Sub procedure to determine which version of DAO your project is referencing.

  1. Open the workbook in Microsoft Excel.


  2. Start the Visual Basic Editor by pressing ALT+F11.


  3. If the Project window is not visible, on the View menu, click Project Explorer.


  4. In the Project window, make sure the workbook is active. For example, click "VBAProject (Book1.xls)" to activate Book1.xls.


  5. On the Insert menu, click Module.


  6. Type the following code in the module: 
    
      Sub Return_DAO_Version()
         MsgBox DBEngine.Version
      End Sub


  7. Press ALT+F11 to switch to Microsoft Excel.


  8. On the Tools menu, point to Macro, and then click Macros.


  9. Click the Return_DAO_Version macro, and then click Run.


You receive a dialog box with the version of DAO that is referenced.
