ApplyRange, VIRTUAL, PROC

The ApplyRange method applies the range limits and calls the ApplyFilter method if the range limits have changed. The ApplyRange method returns a value indicating whether or not a change occurred. A return value of one (1 or True) indicates a change; a return value of zero (0 or False) indicates no change.

The AddRange method specifies the range limits for the ViewManager object. The SetSort method sets the active sort order.

Implementation:

The ApplyRange method applies range limits and filters with the ApplyFilter method.

Return Data Type:     BYTE

Example:

MyView.AddSortOrder(ORD:ByCustomer)                       !sort by customer no

MyView.AddRange(ORD:CustNo,Relate:Orders,Relate:Customer) !range limit by parent file

!program code

MyView.ApplyRange                                         !apply the range limit

MyView.Next()                                             !get next, subject to range
