extrange AV when exiting app

rbuser

Hi!

I'm using RB 10 and Delphi 7 Pro.
After previewing some 'rtm' templates on a ppViewer, looping thru report
objects, changing theirs DataFields, etc... I get an AV when closing the
application (not before). Everithing work fine, but the Access Violation.
The application closes, but the taskbar icon stills appears for a while and
then raises the AV.

It seems like a memory problem or maybe I didn't "freed" the ppViewer or
reports used after changes.
Is it possible to "clear", "cancel", "free" or something the ppReports,
ppViewers, etc... before exiting the app?

I will post or send you some code explaining what I do when I loop through
the report objects if yo need it.

Thanks!

Hi Luis,

Are you able to trace into the RBuilder source or your own and see where the
problem is occurring. The destroy sequence is very precise in
ReportBuilder, if you are manually freeing something that is still in use,
it is very possible to receive an AV.

Hi, Nico...

I'll try to trace the code, but please, can you give an example of the
destroy sequence?

This is what I do:
* Load a rtm template
* I create a ppReport variable ("report") and assign it to the TppReport
component:
report := Form1.ppReport1;
* I loop through the objects of "report" and make some changes:
datapipeline, datafields, value-formats, etc...
* After that, I assign that 'report' to a ppViewer:
ppViewer.Report := Report;

I have noticed that if I don't preview the modified report in the Viewer, no
AV is raised, but I have to be sure, so I will test it again.

Thanks! and Merry Merry X-Mas!!!

Hi Luis,

Did you have a chance to trace your code and the RB code? It would be very
helpful to know where and how this AV is occuring.
