How undo record but don't use the record number

I have this code to undo a record entry on a form, but it seems to use the PK number and I don't want it to do so.  I can I prevent that from happening?  When I attempt to then enter a new record the PK number has been used.

Private Sub cmdUndoRecord_Click()
On Error GoTo cmdUndoRecord_Click_Err

    On Error Resume Next
    DoCmd.RunCommand acCmdUndo
    If (MacroError <> 0) Then
        Beep
        MsgBox MacroError.Description, vbOKOnly, ""
    End If

cmdUndoRecord_Click_Exit:
    Exit Sub

cmdUndoRecord_Click_Err:
    MsgBox Error$
    Resume cmdUndoRecord_Click_Exit

End Sub

Steve,

 You can't prevent that from happening.  With a ACE database, the autonumber is assigned as soon as a record is started.  With some DB's it's not done until after a record is saved, but that's not the way it works with ACE.

You can assign your own number if you want, but I have to say, you should not be counting on the value of that anyway.  It's nothing more then a "tag" or "pointer" for the record and is meaningless out of that context.

If your trying to use it for something else, your using the wrong thing.

Jim.
