[AccessD] Dirty Cancel Clear all controls

[Jim Dettman]

Bob,

   A couple things:

  Me.Dirty = False is equivalent to Me.Undo for the record and you will be
back to default values.

 The alternative is Me.Undo, but the catch there is you may need two; one
for the control (if it's dirty) and then one for the record.   Most use
Me.Dirty = False because it covers everything. You only need one or the
other.

 You can't clear controls like this as not everything can be modified (i.e.
an autonumber).   I would either:

1. check the field type it's bound to
2. rely on the enabled field (assuming everything you want cleared is
enabled).
3. Use a tag in the control Tag property if it should be cleared or not.

 With that said though, you usually want new records to be at their
defaults.   If you don't, then maybe you want to clear all the default
values.

 Also instead of a zero length string, you should be setting the control to
Null.

Jim.

I think me.undo is working. But need to clear entries to get to an unsullied
new record.

See on the web that some variable set and checked in the beforeupdate event
might help.....

Private Sub cmdCancel_Click()

 On Error GoTo cmdCancel_Click_Error
 
    If Me.Dirty Then Me.Dirty = False
    'DoCmd.GoToRecord , , acNewRec
     Dim ctlC As Control
        ' For each control.
       For Each ctlC In Me.Controls
           If ctlC.ControlType = acTextBox Then
                ' Clear New Value.  THIS IS WHERE THE ERROR HAPPENS ON THE
CONTROL FOR THE PRIMARY KEY ++++
               ctlC.Value = ""             '        Me.txtEquipID
           End If
        Next ctlC
   Me.Undo
   
    Me.txtEquipID.SetFocus
    

   On Error GoTo 0
   Exit Sub

Hello to the list,
I am looking to allow my user to bail and trash all info entered and not
save the record. And goto a new record.
Have a button "Cancel".
I have used the isdirty and the cancel methods of the form.
Somehow not getting it done.

Maybe the order in which I am attempting ??
