This article shows you how to use the Application.SetOption method to disable warning messages in an Access application.

This article assumes that you are familiar with the programming language that is being demonstrated and with the tools that are used to create and to debug procedures. Microsoft support engineers can help explain the functionality of a particular procedure, but they will not modify these examples to provide added functionality or construct procedures to meet your specific requirements. Action queries and other processes that append, delete, or modify data typically present the user with a warning that the data is about to be modified. In a run-time application, however, it is often desirable to disable the warnings because checks and precautions are usually beyond the user's control.

You can accomplish this by using the SetWarnings method of the DoCmd object, but you may prefer to disable warnings for the entire application. To do that, you can use the SetOption method of the Application object. However, if you do so, you should also turn the warnings back on as the application quits.

To do this in a simple, one-form application, follow these steps:

1. Start Access, and then create a blank database named TestRun.
2. Import the Customers table from the Northwind.mdb sample database.
3. Create a new form in Design view, and then add an unbound combo box to the detail section.
4. Set the following properties for the combo box:

      Name: cboCountry
      Row Source: SELECT DISTINCT Customers.Country FROM Customers ORDER BY Customers.Country; 
   					

5. Add a command button to the detail section of the form and name it cmdDelete.
6. Set the OnClick property of the command button to the following event procedure:

   DoCmd.OpenQuery "qryDeleteCustomers"
   					

7. Close the Visual Basic Editor.
8. Save the form as DeleteCustomers, and then close it.
9. Create a new query in Design view, and then add the Customers table.
10. In Access 2002 or in Access 2003, click Delete Query on the Query menu.
    
    In Access 2007, click Delete in the Query Type group on the Design tab.
11. Drag the asterisk (*) from the field list to the first column of the query design grid, and then drag the Country field to the second column.
12. In the Criteria row of the Country column, type the following:

       Forms![DeleteCustomers]![cboCountry] 
    					

13. Save the query as qryDeleteCustomers, and then close it.
14. Open the DeleteCustomers form in Form view.
15. Select a country from the combo box, click the command button, and note the warning that appears. Click No in the warning dialog box.
16. Open the form in Design view, and then on the toolbar, click the Code button.
17. In the Code window, type or paste the following procedures:

    Private Sub Form_Load()
    
       Application.SetOption "Confirm Action Queries", 0
       Application.SetOption "Confirm Document Deletions", 0
       Application.SetOption "Confirm Record Changes", 0
    
    End Sub
    
    Private Sub Form_Unload(Cancel As Integer)
    
        Application.SetOption "Confirm Action Queries", 1
        Application.SetOption "Confirm Document Deletions", 1
        Application.SetOption "Confirm Record Changes", 1
    
    End Sub
    					

18. Close the Visual Basic Editor, and then save and close the form.
19. Open the DeleteCustomers form, select a country, and then click the command button.
    
    Note that no warning dialog appears.

In this example, the application's confirm options are disabled when the DeleteCustomers form is loaded and re-enabled when it is unloaded. In a more elaborate application, you might carry out the same actions in a startup form or switchboard.
