raCodMod unit

rbuser

Hi,
My application, built with Delphi 6 and using ReportBuilder 7.04, displays
random AV errors on rbRAP76.bpl.
Using EurekaLog I see that the exception happens in
TraCodeModule.GetAllProgramCount method found in raCodMod.pas unit.
Trying to trace the error I would like to have the source code of this unit,
but I can't find it.
Can you help me with this ?

Thanks in advance

I recommend updating to RB 10.04. Over time we have fixed some intermittent
AV's that a few customers were reporting. You can download a trial version
from our web site if you would like to peform some testing.

We literally do not have the RB RAP source code for RB 7.04.

Thank you for your answer Nard.
I upgraded to ReportBuilder 10.04, but the AV's keep on raising at the same
point.
Here is what happens:
I need to create some TppReports and when I free them rbRAP106.bpl sometimes
raises AV errors.
The only solution I found, was a suggestion from you some years ago in a
similar situation, to use TppReport.Template.New instead of TppReport.Free.
This eliminated the AV's but, since TppReports are not freed, my application
consumes small amounts of memory with the execution of each report. Not a
big issue but not politicaly correct.
Can you provide any more help ?

Thanks in advance

- For any objects that you create in code (report, label, etc) make sure
that use the main report.Owner as the owner.

- For any elements that you add to a band, set object.Band (do nto call
Band.AddObject). Likewise if you create a band and add to a report, set
Band.Report (do not call Report.AddBand).

example:

myLabel := TppLabel.Create(Report.Owner);
myLabel.Band := Report.DetailBand;



- If you still have an issue and would like to create a simple focused
example and to support@digital-metaphors.com and we can check it out. Please
use standard Delphi components, RB and the DBDemos data.

Thanks again Nard,
but the main report is also created in my code, and it's owner never gets
freed.
Perhaps it will help me if you can explain me why freeing a report in my
code, causes these random AV's in rbRAP106.bpl.

BTW the reason I need to create the reports in my code, is because I want to
use existing reports as dynamically created subreports in a main report,
which RB7 did not support.
If this by any chance is supported in RB10, then we probably have a
solution.

PS. A feature I would very much like to see in RB is the ability to find and
replace text in RAP functions, or even better to be able to export and
import all the RAP functions of a Report in a whole text, so that I can edit
them as a whole in another editor.

- creating reports in code is no different than creating reports via the
designer. The designer is essence a visual layout tool that is creates the
report in code for you.

- simples way to use an existing report as a subreport is to save the report
.rtm and then load it as a subreport. You can do this via the designer or
programmatically.

- the alternative for using an existing report as a subreport, is to use a
technique we call 'reference subreports' in which the subreport.Report
property references an external TppReport instance. This is tricky and can
cause AV's in the destroy process, unless you follow the technique shown in
this example

- This example shows how to iterate over RAP event-handlers and modify the
program text.
