barcode 128 in report

[Bubsi]

Has anyone experience using the barcode 128 in a paradox report.
I have a number with 1 to 7 digits and want to print this number as a barcode on a report.

The problem is how to calculate the checksum.
If I'm right I need also a symbol for the start and the end of the barcode.

Thanks Peter

Now I found a simple method:

-Install a barcode font; but be sure that the font works; there are many fonts for free download, but some of them didn't work correct.

- change the actual font in your reportfield for your data into the barcode-font.

- the most barcodes needs additional characters as start/stop character,which you must add.

- some barcodes needs also a checksum which you must calculate.

- The easiest code is barcod 39: For start and stopp characters you must add only *. You don't need a checksum.

Example: You will show 1234567 as a barcode, your data must have the form *1234567*.
