How do I suppress the "You cannot save the record at this time" message

Hey Experts,

I have a strange problem. I have some code in the before update event of a  form that checks for duplicate values. If it finds duplicates it warns the user with a message and sets cancel to true.

All this works great unless they try to x out of the form. When that happens, they get the warning message PLUS the "You cannot save this record at this time" message.

Here's the simple code:

If DCount("*", "tblTeacherAssistants", "LastName = """ & LastName & """ and FirstName = """ & FirstName & """ and SiteID = " & SiteID) > 0 Then

    MsgBox "The combination of Last Name, First Name and Site has already been entered. To back out of this entry, please press Esc." & vbCrLf & vbCrLf & "You can use the Find and Filter features at the top of this form to find the entered Teacher Assistant.", vbCritical
    Cancel = True
End If


It feels like I've done this a thousand times and never got this message.

I would like to allow the user to simply x out of the form and let the data be saved by default.

Can some one help me on how to do this.

Thanks,
EEA

You mean not saved yet by default?

If so, you need to do:

On Error Resume next
Me.Undo
Me.Undo

in the OnUnload event, which undoes all the current edits so the current record is not saved.

No, I actually want to allow the user to SAVE by default. I'm just not sure why the message is coming up. I feel like I've done this a thousand times and never had this problem.

I don't want to do a Me.Undo, because I'd like to give the user a chance to make a change to the entered data.

Any ideas?

Is the User actually hitting ESC, and then the message is happening ?
Do you have a multi field  unique index in the table that does not allow dups on these 3 fields?
That error message usually occurs when ... a user tries to close the Form ... and the dup condition exists ... and you have a unique index in the table to prevent dups

You night try this:
If Dcount( ........  Then
     MsgBox ....
     Cancel = True
     Me.txtFirstName.SetFocus ' so user can make change(s)
 End If

Their getting the second message because your canceling the event and therefore the save.

 I guess I don't understand....you warn them, then cancel the save, but when they hit the X, you want the record saved without warning or no?

 Seems to me you want to warn them, but not cancel the save unless they elect to.

 The second message by the way can be trapped in the forms OnError event and in that event, by setting the Response variable, you can control whether Access displays a message to the user or not.

The Exit Sub and the .Setfocus didn't help. Urg!

I think I'm going to have to add an official save button. But I'd love to know if there is a work around for this.

Any other ideas?

Best,

This is a common problem.  The user makes a change and presses the x to close the form.  As long as the record is valid, the save is completed without error and the form closes.  The problem is when there is an error and the BeforeUpdate event is cancelled or if there is an RI error and Access itself prevents the record from being saved.

The simplest way to solve the problem is to create a form level variable.

Dim bAllowClose as Boolean

In the Form's Current event sent the variable to true.
bAllowClose = True

In the Form's BeforeUpdate event set the variable to false.
bAllowClose = False

In the Form's AfterUpdate event set the variable to true
bAllowClose = True

Then in the form's unload event, check the variable.  Here you can give the user the option of not closing the form and going back to correct the error or to exit without saving.

If bAllowClose = True Then
    Exit Sub
Else
    If Msgbox("An error was discovered.  Press Yes to return to fix it.  Press No to exit without saving the change.",vbYesNo) = vbYes Then
        Cancel = True
        Exit Sub
    Else
        Me.Undo
        Exit Sub
    End If
End If
