ACC: Form Is Editable Even When AllowEdits Property Set to False

• Microsoft Access versions 7.0, 97

SYMPTOMS

When you open a Microsoft Access form that has the AllowEdits property set to No (False), you can still edit the fields on that form. This article assumes that you are familiar with Visual Basic for Applications and with creating Microsoft Access applications using the programming tools provided with Microsoft Access. For more information about Visual Basic for Applications, please refer to your version of the "Building Applications with Microsoft Access" manual.

CAUSE

This behavior occurs if you set the value of a control programmatically in the Current event of the form. It also occurs if you set the value of a control in the Load event of the form. In that case, however, the only record that you can edit is the first record that is displayed on the form.

RESOLUTION

If you need to edit the values of bound fields programmatically in forms that have the AllowEdits property set to False, edit those fields in the RecordsetClone of the form, and not in the form itself.

The following example demonstrates how to create Visual Basic code in the Current event of a form that can change the values of fields in the RecordsetClone of a form.

CAUTION: Following the steps in this example will modify the sample database Northwind.mdb. You may want to back up the Northwind.mdb file and perform these steps on a copy of the database.

1. Start Microsoft Access and open the sample database Northwind.mdb.



2. Open the Customers form in Design view.



3. Set the AllowEdits property of the form to No.



4. Set the OnCurrent property of the form to the following event procedure:




      Private Sub Form_Current()
      Dim rs As Recordset
      Set rs = Me.RecordsetClone
      rs.Bookmark = Form.Bookmark
      rs.Edit
      ' The following updates the CompanyName field to itself plus the
      ' letter "a".
      rs!CompanyName = rs!CompanyName & "a"
      rs.Update
      End Sub 

5. Save the form and open it in Form view. Note that each time you view a record, the letter "a" is appended to the Company Name, but you cannot edit any of the fields on the form.

Steps to Reproduce Behavior

1. Start Microsoft Access and open the sample database Northwind.mdb.



2. Open the Customers form in Design view.



3. Set the AllowEdits property of the form to No.



4. Set the OnCurrent property of the form to the following event procedure:




      Private Sub Form_Current()
      ' The following updates the CompanyName field to itself plus the
      ' letter "a".
      Me!CompanyName = Me!CompanyName & "a"
      End Sub 

5. Save the form and open it in Form view. Note that each time you view a record, the letter "a" is appended to the Company Name, and note that you can also change other fields on the form.



6. Press CTRL+G to open the Debug window.



7. Type the following in the Debug window, and then press ENTER:

   ?Forms!Customers.AllowEdits

   Note that the property is set to False, but that you are able to edit fields on the form.
