Stonefield Query calls the ReportEngine.SetupCrystalReport script when the users runs a Crystal report. This allows you to change the report's properties before it runs.

A reference to the Stonefield Query Application object and a reference to the Crystal report object.

Return Value
True if the report can run, False if not.

This example sets the value of the tsDataFolder variable in the Crystal report to the name of the current database.
