asked on

File value being changed upon changing another field via a form

I have a a field called  "FileNo"  this number is generated automatically via

Private Sub Form_BeforeUpdate(Cancel As Integer)
Me.FileNo = Year(Date) & "1" & Format(Me.InvoiceID, "00000")
End Sub.


The problem is that I have a record that was created last year as example

FileNo =  201312345677

when  a user opens the record via the form and changes one of the field values the FileNo is being recreated and saved as :

FileNo = 201412345677


ONce the FileNo is originally created I do not want it changed no matter what other changes to the record are being made subsequent to the intial creation of the FileNo.


Please help.

You can use:

Private Sub Form_BeforeUpdate(Cancel As Integer)
  If isNull(Me.FileNo) Then
    Me.FileNo = Year(Date) & "1" & Format(Me.InvoiceID, "00000")
  End If
End Sub

/gustav
try this


Private Sub Form_BeforeUpdate(Cancel As Integer)

if me.newrecord then

          Me.FileNo = Year(Date) & "1" & Format(Me.InvoiceID, "00000")

end if
End Sub
