Access Violations at design time

rbuser

I am getting a ton of access violations and "invalid pointer operations" at
design time when switching between preview and back. I am using D7 and RB
Enterprise.

Any suggestions?

Reid,

Are you using ReportBuilder 7.02 Build 2? If not, please download the
latest version. Make sure your report object is located on a Delphi form
and not a datamodule or webmodule. Can you see these AV's when running our
demo projects? If so, please provide the exact steps you took to create
these errors so we can try to re-create the issue here.

Hi Reid,

Check that the .dcu files located in the \RBuilder\Lib\... directory are
dated 03/03/17 7:02am to be sure you have the latest version of
ReportBuilder. Are you able to reproduce the AV errors that you were
receiving with our demos? You should be able to use a DBCalc instead of
trying to count the GroupHeaderBands.

The reason the code scrolls behind the scenes when loading a report is that
when RAP is being used at Delphi design time, your report is created behind
the scenes on the form to save the layout before the report begins
generating to the design-time previewer. The reason is RAP code during
report execution can change the layout. When you return to the design
workspace, the cached template is re-loaded restoring your template to its
origonal settings ensuring that your RAP code did not change your layout so
the next time you run your report, it will run correctly.
