VBA (Access) & Postcodes

Hi, Can anyone help please.

In access 97, Customer table : Name: Address: PostCode: TelNo: Etc.

Within the UK any one PostCode can have 4 different ways of being presented, I.E

Examples.

AB10 1AB
AB101AB

Some PostCodes areas have only 1 number at begining,

AB1 1AB
AB11AB

All 4 are correct, but when exported for a courier company to use the Postcode format is not allways correct to what they want.

Can I Use code to select different InputMasks for each PostCode, This allowing any user to type however they want into that field but the end result is what is required. Below is whats accepted.

AB10 1AB Correct
AB101AB Should be AB10 1AB
AB1 1AB Correct
AB11AB should be AB1 1AB.

Code i'm playing with is:

Private Sub Post_Code_AfterUpdate()

Trim (Me.Post_Code) 'Remove spaces start/end (not working)

If Len(Me.Post_Code) = 7 Or Len(Me.Post_Code) = 8 Then
Me.Post_Code.InputMask = ">LL00 0LL;;_"
Else
Me.Post_Code.InputMask = ">>LL0 0LL;;_"
End If
End Sub

HELP Please!!!

:)

Input masks don't format (only in appearance) the underlying string if the string is ALREADY entered.
But try this exercise as a workaround:

Code:

---

Private Sub Text1_Enter()
Me.Text1.Text = ""
' # means space or digit.
'sets it at a length of 7 to start.
'If you choose not to preset a mask, then you'll
'need to format multiple cases after entry.
Me.Text8.InputMask = ">LL0#0LL;;_"

End Sub

Private Sub Text1_Exit(Cancel As Integer)
Dim s As String
s = Trim(Me.Text1.Text)

If Mid(s, 4, 1) <> " " Then
  'this makes it appear formatted in the textbox
  Me.Text1.InputMask = ">LL00 0LL;;_"
  'do manual formatting
  s = Left(s, 4) & " " & Right(s, 3)

Else
  'already formatted as entered.
End If

MsgBox Len(s)
MsgBox s
End Sub
