Hello,
you should enable Code39 Full ASCII in the barcode reader to get a chance to read it.
To add a counter in your report you should query a table to get some records, I use sysobjects table in MS SQL which contains a lot of records like:
select
row_number()over (orderbyid)asLabelNumber
from
sysobjects
then use a Record selection formula in Crystal Reports to get the exact number of records/labels as the user input in the parameter:
{Command.LabelNumber} <= {?LabelNumberParameter}
Now create a Running Total that just count records a put it in detail section...
Hope it helps
Regards
Pierre
