Dynamically adding RB components to Detail Band

rbuser

Hi,

I am trying to create a bardcode for our inventory list. But, with my
limited knowledge on RB product, I found myself only be able to add one
barcode per detail band print.

What I would like to do is print multiple barcodes across the detail band
with each barcode matching the our inventory items. It would be similar
to the address label printing.

After playing around for few hours, I have done it with multple DBBarcode
components placed at the design time and playing with the visible property
at runtime.

It works but I would like it in a cleaner way and I think the cleaner way
is to dynamically add the barcode components at runtime.

So, I've tried

OnBeforeGenerate (detail band)
Barcode = TppBarCode.Create(detailband);
... set other properties..
DetailBand.AddObjects(BarCode);

But, that didn't work--it did not print the barcode. Also, I was getting
AV after closing the app with that code added.

So, my question is, is there a way to dynamically add components at runtime ?

TIA,

SeHun

Try configuring the report to print columns. From the report designer,
select File | PageSetup |
Layout. You can specify number of columns and TopToBottom or LeftToRight
traversal.

Here is a list of resources for learning RB. I recommend spending time now
to learn the fundamentals of the product. This will enable you to leverage
the power of RB productivity and minimize frustration.

---------------------------------------------------------------
Article: Resources for Learning ReportBuilder
---------------------------------------------------------------

1. Learning ReportBuilder is a complete learning system designed to teach
end users how to build a range of reports, but it is also an excellent
resource for the developer who is just getting started with RB. Learning RB
includes a 125-page PDF file, a stand-alone application complete with a
database, and a help file. The PDF file contains a set of tutorials, which
can be completed using the provided application. Learning ReportBuilder can
be downloaded from:

http://www.digital-metaphors.com/LearnRB/LearnRB.exe

2. Learning to RAP is designed to teach end-users how to use ReportBuilder's
Calc workspace to perform calculations and control visual aspects of the
report while it is generating. Learning to RAP includes a 59-page PDF file
and a stand-alone application complete with a database. The PDF file is
comprised of a series of tutorials that step end users through the process
of coding calculations and event-handlers to dynamically control report
generation. The application is used in conjunction with the tutorials so
that the learning experience is interactive. Learning ReportBuilder - RAP
can be downloaded from:

http://www.digital-metaphors.com/LearnRB/LearnRap.exe

3. Developer's Guide

When you install RB, this guide is automatically installed into the
RBuilder\Developers Guide directory. It contains extensive conceptual
information and step by step tutorials which show how to construct reports
and reporting applications within the context of the Delphi IDE.


4. On-Line Help

Accessible via a single click of the F1 key from with the Delphi IDE, this
reference resource explains the classes, methods, properties and events
which make up the product. It is also an excellent source of information
regarding installation, troubleshooting and version history.


5. Examples

There are a large number of example reports and reporting applications
included with RB. These show how to accomplish some of the most frequently
requested types of reports. In total there are probably over 200 different
examples covering everything from crosstabs to full-blown end-user reporting
solutions. The RAP functionality included with ReportBuilder Enterprise has
a separate set of demos, tutorials, and help files.


6. news.digital-metaphors.com

The newsgroups are very active with both Digital Metaphors engineers, TeamDM
members (volunteers specially selected for their knowledge of RB and their
willingness to help) and RB developers all pitching in to answer questions
and help each other out. There is also a Tech Tips 'newsgroup' maintained
by DM Engineers which lists over 100 different articles outlining various
tips and techniques. Probably the easiest way to connect to the newsgroups
is to surf the digital metaphors site, go to the support section and click
the newsgroup of your choice:

ReportBuilder newsgroup archives may be searched using a search engine
hosted by Tamarack Associates. Access the the following URL and then search
the Borland Newsgroup database. Tamarack has indexed the ReportBuilder
newsgroup archives in this database.
