SP2.

About this class
UpdateListener is deprecated in SP2, because you can use the fxTherm FX object with FXListener to meet the same design goals as described in this topic. However, UpdateListener was back-filled with all changes, fixes, and enhancements to the feedback feature set that fxTherm received. This enables you to continue to use UpdateListener if you don't need the VFP 9 Reporting FX subsystem; it has slightly less overhead.
For information about enhancements to UpdateListener in the SP1 timeframe, please see the section on Effects on derived classes related to the pagelimit feature set of FFC ReportListener Base Foundation Class (_ReportListener).
The following table
lists a public property added by this class to its parent class, _ReportListener, and new in SP2.

"listener.vcx",_REPORTOUTPUT)
