Message Box Question

Hello all
I am hoping that somebody will help me with
a code solution to indicate that the length
of a text box entry is to short.

The text box is for UK post codes and they should
have more than for characters... is there some way
to create a messgae box that will tell the user
that they need to add some more text

thanking you for any advice

Bob

Hello Bob,

Put the following code in the BeforeUpdate event of the textbox:
If Len(Me!NameOfTextBox) 5 Then
MsgBox "You Need To Add More Some More Text",,"UK Post Codes Have More Than
Four Characters"
Cancel = True
End If

Great, this works very well - thanks very much

Is it a complicated job to add another validation into
these types of code, say that you needed the first
digit has to be a letter or the testbox needs a
combination of both


thanks a lot for the coding

Bob

if your postal code is a set length, you can use the Input Mask - either at
the table level or at the form level - to validate the characters entered.
if you set it at the table level, it carries over to any new forms you
create afterward, using that field; if you set it at the form level instead,
it only applies to the form you set it in.
as an example, U.S. postal codes are either 5 digits or 9 digits in length -
the first 5 digits are always required, but the last 4 digits (usually) are
not. so i set an Input Mask on that field as

00000\-9999;;_

that tells the system that the first 5 characters must be numbers and are
required, then show the hyphen - , then the last 4 characters must be
numbers but are not required.
the Input Mask wizard will build some standard masks for you, or you can
build custom masks yourself. to use the wizard: open the table or form, go
to the field (control, in a form), click on the Input Mask line in
Properties, and click the Build button at the right (...).
recommend that you read up on input masks, whether you build your own or use
the wizard. to do so, click on the Input Mask line in Properties, from the
open table or form, and press F1. Access Help will open to the appropriate
topic.
btw, an added bonus of using an input mask is that, in a form, you can set
the text box control's AutoTab property to Yes. then when the input mask is
filled during data entry, the cursor will automatically move to the next
object in the tab order, without the user having to hit Tab or Enter.

Hi Bob,

There's no simple way of validating UK postcodes. In particular, it
can't be done with Access's Input Mask feature. And of course if you set
your database to insist on something that looks like a UK postcode,
you'll make it impossible for a user to enter an overseas address.

If that doesn't matter, you can get a short way by using the VBA Like
operator, e.g.

Dim strPC As String

StrPC = Me.NameOfTextBox.Value

If (Len(strPC) 6) Or _
Not ((strPC Like "[A-Z]#") Or (strPC Like "[A-Z][A-Z]#")) Then
'can't be a valid UK postcode

but for a much more powerful and flexbile approach take a look at the
rgxValidate() function at http://www.mvps.org/access/modules/mdl0063.htm
