MardiL,

There is no "built-in" facility for creating barcode check
digits. Have a look at the following site to understand
how to generate your own checkdigit.

http://www.spatula.net/proc/barcode/code39.src

A table with each character and it's associated value
would be one method of easily getting the required values.

You could create your own function and and in the control
source something like:
="*"& 39checkdigitfunction([myData])&"*"
with the font set to your 3of9 font.

In most cases (that I've seen) people don't create a 3 of
9 with the check digit - the check digit is optional.

Oooops the hypothetical formula I gave didn't include the
data .... only the checkdidgit. Should have been:

="*" & [myData] & 39checkdigitfunction([myData]) & "*"

Please take a look at BarCodeWiz Barcode ActiveX Control.
http://www.barcodewiz.com

The ActiveX is a plug-in that can be used with Access reports to
generate barcodes as images. Simply set the control source to your
table field, set the Symbology property to Code 39, and the
OptionalCheckChar property to "1-Barcode Only" (if you do not wish to
show the check digit in human readable text), or "2-Barcode and Text".
The check digit will be automatically calculated and included in the
barcode.

If you need any help, please feel free to ask.

The easiest way to print bar codes in Access is to use an ActiveX
control that is designed for printing bar codes. Bar Code Fonts
generally do a very poor job at creating readable bar codes and if you
want check digits in bar codes created with fonts, be prepared to
write some code.
The best bar code ActiveX control available is from TAL Technologies
and you can download a demo version of it from the following web page:
http://www.taltech.com/products/activex_barcodes.html
The TAL ActiveX control supports optional Code 39 check digits that
can be enabled by setting a "Code39OptionalCheckDigit" property to
True. The optional check digit is a MOD 43 check digit as is
recommended in the official Code 39 specification.
