This is component library including Barcode generator.

At this time, it supports EAN/JAN and CODE-39 format

* Will update here when other format is available

Input properties

InputCode (Text type) : Barcode data

AutoCheckDigit (Boolean) : If true, add/replace auto-calculated digit.

I found a bug at the check digit calculation.

----------

(10-Right(Text(Sum(Sequence(6,2,2),Int(Mid(JAN_EAN.InputCode,ThisRecord.Value,1)))*3+Sum(Sequence(6,1,2),Int(Mid(JAN_EAN.InputCode,ThisRecord.Value,1)))),1))

----------

When this result is "10", the correct check digit is "0".

But the logic returns "10".

I fixed as the following.

----------

Mod((10-Right(Text(Sum(Sequence(6,2,2),Int(Mid(JAN_EAN.InputCode,ThisRecord.Value,1)))*3+Sum(Sequence(6,1,2),Int(Mid(JAN_EAN.InputCode,ThisRecord.Value,1)))),1)),10)
