    <p>I was unable to hit 115mm exactly. Here's one that will print at a little over 116mm on all three of my printers and from IE or Firefox. Adjusting the width to 19 gets you down to about 109mm...</p> <p>I am using a separate png image for each symbol and stringing them together on the client side.

    1. COso, what you are saying is that I should build my own barcode by "concatenating" several <img> of the specific widths in millimeters?

    3. COI used to use barcode fonts back in 1987, but I had the same problem with control over the exact width of the final complete barcode and my customer wanted me to hit the mark pretty exactly. So I studied the PostScript language and created something similar to the above in PostScript. Thinking of a barcode as the tiniest series of dots and spaces and scaling up from practically invisible to full size gave me the control I needed. Last year I started looking around for another job and decided to modernize my 25 year old technique for the WWW. Easier when generated using javascript or excel.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
