We recognize that the Carolina Barcode UPC Barcode Font is more difficult to use than our popular Code 39 barcode font. Although it is possible to use the colored keyboard and check digit calculation method we mentioned on the UPC Barcode Font Primer page, we've put together an Microsoft Excel worksheet that will do the calculations for you.
The worksheet is in Excel 2000 format and can be downloaded here:
To make it even easier, we've put together a video presentation to show you how to use it. The demo assumes that you've downloaded and installed the Carolina Barcode UPC Barcode Font from the links on this page.
In the worksheet, we've coded a Macro which defines a function to do the calculations. You can see the function call (similar to the =Sum(_) function you may be familiar with) if you put the focus on cell C2. You can use the code from this function to integrate the Carolina Barcode UPC font into your applications such as Microsoft Access, Visual Basic or any of the Visual Studio Products.
Since a picture is worth a thousand words, we suggest you watch the video.
