by This sub-routine will produce a barcode from any alphanumeric string. The barcode is be made of a table with individual black and white images making up the individual lines. It can also be printed from the browser.
Add the script below to your own ASP script, or create an include file for it. You need a couple of image files to ensure that the barcode will display and print correctly. These are just 1px by 1px white and black 'GIF' files and you can download them below.
To call the barcode sub-routine use the following syntax (where data is the text or numbers in the barcode, height is the height in pixels (defaults to 30), width is the width in pixels (either 1 or 2 works well, default is 1), and text is a boolean value for whether you want the barcode data printed below the barcode:

Please note that bar codes may be difficult or impossible to scan if printed on anything other than a laser printer or similar high quality printer.

Did you mean the demo didn't work? It was missing some image files which I've added now and it is working again.

Dont suppose you have some classic ASP magic for a QR code or how to get longer datastring into your example above without the barcode becoming massive.

If you have set the width to the minimum of 1 then that is as narrow as a barcode can possibly get. Some other types of barcodes might be more efficient if you have the option to use a different type. QRCodes are quite efficient in size.
