See Also

This example demonstrates setting the CursorType and LockType properties before opening a Recordset. It also shows the value of the EditMode property under various conditions. The EditModeOutput function is required for this procedure to run.

Public Sub EditModeX()

   Dim cnn1 As ADODB.Connection
   Dim rstEmployees As ADODB.Recordset
   Dim strCnn As String

   ' Open recordset with data from Employee table.
   Set cnn1 = New ADODB.Connection
   strCnn = "Provider=sqloledb;" & _
      "Data Source=srv;Initial Catalog=Pubs;User Id=sa;Password=; "
   cnn1.Open strCnn
      
   Set rstEmployees = New ADODB.Recordset
   Set rstEmployees.ActiveConnection = cnn1
   rstEmployees.CursorLocation = adUseClient
   rstEmployees.CursorType = adOpenStatic
   rstEmployees.LockType = adLockBatchOptimistic
   rstEmployees.Open "employee", , , , adCmdTable

   ' Show the EditMode property under different editing
   ' states.
   rstEmployees.AddNew
   rstEmployees!emp_id = "T-T55555M"
   rstEmployees!fname = "temp_fname"
   rstEmployees!lname = "temp_lname"
   EditModeOutput "After AddNew:", rstEmployees.EditMode
   rstEmployees.UpdateBatch
   EditModeOutput "After UpdateBatch:", rstEmployees.EditMode
   rstEmployees!fname = "test"
   EditModeOutput "After Edit:", rstEmployees.EditMode
   rstEmployees.Close
   
   ' Delete new record because this is a demonstration.
   cnn1.Execute "DELETE FROM employee WHERE emp_id = 'T-T55555M'"

End Sub

Public Function EditModeOutput(strTemp As String, _
   intEditMode As Integer)

   ' Print report based on the value of the EditMode 
   ' property.
   Debug.Print strTemp
   Debug.Print "  EditMode = ";

   Select Case intEditMode
      Case adEditNone
         Debug.Print "adEditNone"
      Case adEditInProgress
         Debug.Print "adEditInProgress"
      Case adEditAdd
         Debug.Print "adEditAdd"
   End Select
