Saving Report to Database having DBTeeChart

rbuser

Hi,

I have RB 701 Ent., Delphi5 Ent., TeeChart5.02 full Ver. MsSQL200

In End User Databases Example (SQL Server 7 With Ado Con.)

After new Report, I use DBChart and Series.
First Seri Has Datapipeline and its drawing is OK.
Second seri is average of the first serie and its drawing is OK.
But after I save the report to database and repen then report there is no
second seri there.
There exists in legend but its drawing is not. When I edit chart the second
serie does not included in selected Serie in Datasource tab page.

Thanks in Advance

There is also first AV then EInvalidPointer Exception ocuurs when I Close
the program.
But if I delete the second serie and save the report then there is no AV
after I close the program.

We haven't added all the extended function series classes to be linked in by
default. Add TeeEditPro to register the class to be linked in at runtime.
This should also link in the other series classes as well.

The AV you are getting is because Teechart source has some bad free
notification setups, where some object references aren't nilled out when
they are freed. When using Teechart in a form environment in a Delphi app,
the timing works out (luckily) so that there isn't a problem. However, in
RB, it is an entirely different environment and it causes an AV on close. We
reported the issue to the Teechart authors a while back and where in their
code the problem was, but have not seen a fix for this at this time.

Ok.
But My problem is that I didnt save the second serie to the database. I
think there is a saving problem.
If First and Second Serie have Datapipeline datasource there is no saving
problem and AV problem. But
If first Serie has Datapipeline Datasource and the Second one has average
funcrion of the first one then
the second serie doesnt saved and AV occurs.
