Report Builder export to PDF causes Access violation

[ricardobh]

When trying to export some reports that use DBRichView, they crash every time with "Invalid pointer operation" error and some access violations after that. Tried with Delphi 11.3/RB 22.0 and Delphi 12.0/RB 22.3 both with TRichView 24.2.
When I noticed that only reports with DBRichView crash, I downgraded TRichView, version by version, down to 23.0.1, when it started working again.
Here's the stack trace, just after the error:

Thank you in advance.

If you use ReportBuilder 22.x, open <TRichView>\ThirdParty\ReportBuilder\Source\Include\RVRB.inc, and remove the line

Code: Select all

{$DEFINE REPORTBUILDER23}

This line is necessary for ReportBuilder 23 and newer.

Does it help?

That solved the problem.
Thank you.
