There are several barcode formats. Some are simple and some can get very complex. One of the easiest to use, if it fits your application, is the 3 of 9 barcode. It is not compressed and there is a 1 to 1 relation to the chars in the barcode.

There are two variants of this, numeric only and the extended set that includes alpha. I'll go forward with the asumption that you can use this format. Visual basic 2010 utorrent.

(From your sample code, it looks like that's what you are using) For the easiest implementation, stick with the numeric only. Then, you will only require eleven chars (0-9 and the astrisk).

Look at the definition of an existing 3 of 9 font. (For non-commercial use, search for a font called FREE3OF9. You can use that as the base for your app.)Next, the tedious part - more work for you up front but displays in almost any browser.

If you can't find any on-line, crerate a GIF (or BMP or PNG) image for each char. (Remeber to include the proper white-space on the right side of the char to distance it from the next char in line!) It only needs to be one pixel high. When the time comes to display the barcode, string the chars together as 's that are next to each other. 3 of 9 requires that the chars in the barcode are surrounded or wrapped with an astrisk (it's the astrisk in the FREE3OF9 font anyway) on each end. Set the height of the 's to something tall enough to suit your printout.This way, no font installation required at the client, but most barcode decoders can read the resulting graphic.Your example (.574656.) might look like this:(well, not exactly like that - it's a solid graphic instead of a composition of several in-line single graphics, but you get the idea)The individual numeric graphics look like this:(although, these are not 'cleaned up' yet).and the code changes might look like this: Barcode Font TestI used as a resource to refresh my memory of how 3 of 9 barcode chars were formatted. These graphics are initially from that site. We have the same problem at my company.

Luckily, only 1-2 people ever need to use the barcode fonts.We have found that when they received new a PC, the fonts didn't work through any browsers. They had to open up a client application (like Word), choose a barcode font, and do some typing to 'initialize' that font.The best solution, I think, is to create a barcode image on the server on demand.

The problem with this solution could be cleaning up old images. This solution requires more work up-front but pays off with less on-going issues and maintenance than the client side solution, in my opinion.
