Coupon Code bar codes are made up of two individual bar
codes placed next to each other. The first bar code is either
a standard UPC-A or EAN-13 bar code and the second bar code
(the extended coupon code) is a UCC/EAN 128 bar code that
is completely independent of the first bar code. All three
types of bar code can be produced by our bar code ActiveX
control.
The trick to producing coupon codes with our activex control
is simply to use two instances of the control and feed the
two independent (UPC/EAN and UCC/EAN 128) bar code messages
to their respective instance of the ActiveX control. The
only requirement is that you print the extended code symbol
a minimum of 10 times the NarrowBarWidth distance (typically
130 mils) to the right of the UPC or EAN symbol to maintain
the quiet zone between the two bar codes.
Occasionally there is a need to save coupon code bar codes
to a disk file in a single graphic file. Unfortunately the
TAL Bar Code ActiveX control does not have the ability to
do this directly however it is possible to use Windows API
functions to combine two bar code images together into a
single graphic file.
The file CouponCode.ZIP (below) contains a sample Visual
Basic 6 program that demonstrates how to combine two bar
code images created with the TAL Bar Code ActiveX control
together into a single Windows Metafile graphic file.
