Hi.

I have made a barcode application.

It's located at http://www17.brinkster.com/myopeneyes

The application generates the barcode but the barcode reader can't read it. Try to solve that problem.

Regards,

Marco Alves.

Normally, you need delimiters. For example, when you are using the 3of9 barcode font, you need to add * has a prefix and a suffix to your data.

ie: if you want to barcode ABC123, you need to print *ABC123* as the barcode.

You need a start and a stop characters. See http://www.adams1.com/pub/russadam/128code.html

What does it mean to be "Always On"?

I already put the start and stop characters. And the checksum too... Please, view the source code of the application at:

It's very easy to understand.

Is it working? I don't have a barcode to test it. And I also didn't look thoroughly the specification!

I just found that the link I gave you is for Code 128 and that you are using EAN128.
