TppDPTeeChart questions

rbuser

Hi,

First attempt at using the Chart and I am having a few issues.

First, I notice in RB that there are 2 chart options: DB and DP Chart. When
I add a TppDBTeeChart to a report and click on the chart property in the
object inspector Delphi closes without any message.

Second, I am working with the DP chart and I cant seem to get anything to
show up in the dataset dropdown on the datasource tab. What do I have to do
to get something to show up in there?

And third, what is the difference between a DB and DP chart?

I am using D7 and RB Professional v9.03

Thanks,
Shane

Hi Shane,

I believe for some installations of RB 9.03, the TppDBChart component was
being installed automatically. This has been fixed for later versions. Do
not use the TppDBChart component, this is included for backward
compatibility with very old versions of ReportBuilder. The proper component
to use is the TppDPChart. Check your installed components in the Delphi IDE
and be sure there is not an entry for "ReportBuilder DBTeeChart 7.0
Component" (rbTDBC97.bpl). If there is, remove this package.

Which version of TeeChart are you using? If you are using TeeChart 4.04
(the version included with Delphi) you will not be able to access data from
the chart at design-time. This can be done at runtime or by upgrading your
version of TeeChart. Take a look at the RBuilder.hlp file under the
ReportBuilder Reference | TeeChart | Delphi 7 | ... section for information
about TeeChart compatibility and limitations.

Hi Nico,

an old message, but a current one for my case, it seems.

When loading a form with a report at runtime, I'm getting the message "Class
TppDPTeeChart not found".
On my search for the reason I've found this post.
I've checked my installed packages and there is one "ReportBuilder
DBTeeChart 9.0 Component" (rbTDBC1215.bpl). Is it wrong to have it there?
I also have this one there "ReportBuilder TeeChart 9 Components"
(dclRBC1215.bpl).

Do I miss the proper package for the TppDPTeeChart class? Or is there
another reason for the message I get?

Regards,
Mark

Hi Mark,


It is not wrong to have the DBChart installed but it is unlikely you
will need it for backward compatibility purposes. You can remove this
package.

At runtime, you need to be sure you have the ppChartDP unit added to
your uses clause before loading a template containing a ppDPChart.

Hi Nico,

thanks for your reply.


We are considering switching to Delphi XE and are testing the whole process
right now.
That means we port our project, which is working with Delphi 2007 just fine.

The unit ppChartDP is not included anywhere and it still works.

Right now the unit ppChartDP.pas is located only in
..\RBuilder\TeeChart\TeePro900 and there is no library / search path set to
this directory (in the original project as well).

Somehow I feel, that either RB or TeeChart (or both) are not installed
correctly. I've tried to execute the RBTeePackageBuilder.exe but it didn't
work, since some packages / units couldn't be found, althought they are
there...

Any ideas?

Regards,
Mark

Nevermind, my bad.

Apparently my colleague had some trouble with the installation and commented
out those units temporarily.
I didn't know about it and thought there is a problem...

It's all good now, sorry...

Mark
