Line Numbering

rbuser

I am trying to number the lines in a report with the line numbers showing on
the detail and the group bands. I have tried using a TppVariable and
incrementing the value in the OnCalc and the OnGetText events. When I use
the OnCalc event the value is incremented twice (not what I wanted). When I
use the OnGetText event, some line numbers are skipped between pages because
the group at the bottom of the page doesn't fit, so it gets new numbers when
it prints at the top of the next page. With both methods, the line numbers
keep getting higher in print preview when I page backward and forward.

Also, the report has three sections, and the line numbers must continue
incrementing and not reset with the start of each section.

Thanks for your help.

Hello,

did you looked at DbCalc. This have a calculation property for lines. i
using it in details and it works fine.

Maybe I'm missing something, but DBCalc doesn't have a calculation type for
lines. I saw in the Developer's Guide that you can use DBCalc to count the
detail records and report the value as a line number, but I need to have a
line number on the group break as well.

Also, each section (I have three) is attached to a different pipe. The line
number should not be reset when proceeding to the next pipe.

hi,

there is a property onright mouse with caclulation.... In this combo you can
sum, avarage, minimum, maximum and you have a linecounter.

Actually, the option is Count. This counts the number of records in the
pipe and not the lines on a page. This works to some extent, in that it
numbers the detail lines. However, additional programming is required to
accurately number the total line. In addition, more programming is required
to synchronize the numbering of the proceeding sections with the numbering
from the first section.

The TppVariable should only fire its OnCalc event once. Use one variable in
the detail band. It will fire once for every traversal. Now, place another
variable in the group footer band. In its OnCalc event handler, increment
the value of the variable in the detail band. You'll need to use the timing
dialog to set the group footer band variable to fire only when the group
footer prints (GroupBeforeFooter in the dialog).

Set Report.CachePages to true, and the pages that have been generated will
be saved when traversing through the pages in the preview.
