The Columns property returns the number of columns defined in an extended fetch record set.
If a SelectedFields property has been specified for extended fetch operations, this value will correspond to the number of fields specified in the
SelectedFields property. Otherwise, it will correspond to the total number of fields defined for a record in the data file (see
Fields property).
This property is not available at design time, read-only at run time. It will contain valid data only after the extended operations Init method has been invoked at run time. The
ExtendedOps property must be set to
True to enable the extended operations capabilities of the VAccess control.
