BUG: 3426 and 3020 - Different Error Number With 16-bit/32-bit

• Standard, Professional, and Enterprise Editions of Microsoft Visual Basic, 16-bit and 32-bit, for Windows, version 4.0

SYMPTOMS

If a Recordset.Update is issued without first issuing an AddNew or an Edit method, Visual Basic 4.0 correctly raises an error, because the Update method can only be invoked after an AddNew or an Edit method. However, the error number raised by the 16-bit and 32-bit editions of Visual Basic differs.

The 32-bit edition of Visual Basic version 4.0 for Windows returns the following error:

   '3020' - Update or CancelUpdate without AddNew or Edit

   '3426' - The action was cancelled by an associated object

STATUS

Microsoft has confirmed this to be an issue in the Microsoft products listed at the beginning of this article. Microsoft is researching this problem and will post new information here in the Microsoft Knowledge Base as it becomes available.

MORE INFORMATION

Steps To Reproduce Problem

1. Start the 32-bit edition of Visual Basic version 4.0 for Windows. Form1 is created by default.

2. Add a single text box and data control to the form.

3. Set the properties of the data control to the following:

         DatabaseName:     BIBLIO.MDB
         RecordSource:     Authors
   
   

4. Set the properties of the text box to the following:

         DataSource:    Data1
         DataField:     Au_ID
   
   

5. Add the following code to the Form_Click event of Form1:

         Private Sub Form_Click()
            Data1.Recordset.Update
         End Sub
   
   

6. Press F5 or click Start on the Run menu to run the application. Change the text in the text box and click the form. With the 32-bit version of Visual Basic version 4.0 for Windows, error '3020' is raised. If these steps are repeated with the 16-bit version of Visual Basic version 4.0 for Windows, the error raised is '3426'.
