>In your ReportListener subclass, you have access to several "things" while the report engine processes a REPORT FORM command. These include several Before and After hook methods, methods like Render and OutputPage, and access to a copy of the FRX that is being "walked" by the engine.

>You can change some options at runtime -- check out the sample code in EvaluateContents.htm and Rotate.htm in the Reporting section of the Beta release notes download. There are BeforeReport and LoadReport methods where you might be able to make changes to the FRX, but there is not very much written about them yet. Most of the clues you can search out are contained in either OA.htm or OAX.htm.
