Extending Report Preview Functionality
In addition to the Report Designer's builder events, which are hooks into the report design process, Visual FoxPro also provides hooks into the process of running reports. These hooks are exposed through the ReportListener, an instance of which is used in object-assisted reporting.
There are two ways to enable object-assisted reporting:
SET REPORTBEHAVIOR 90
Write code that explicitly uses the OBJECT clause on the REPORT FORM Command.
The topics in this section introduce the preview container component used by the ReportListener class when rendering previews in object-assisted reporting, and how to leverage it in your applications.
