說明:
TFieldUpdate allows you to update the fields of a Paradox or DBase database at runtime to
match a set a field definitions supplied either at runtime or design time. The TFieldUpdate
component allows you to add new field definitions to TFieldUpdate.FieldItems, and modify
those
field definitions by setting values for TFieldUpdate.FieldItems.Items[I].Name, .FieldType,
.Length,
and .Precision. You can also populate TFieldUpdate.FieldItems using the procedure
ReadFromFile(), specifying the path to a database from which to read the field definitions. This
procedure is available at design time using the property TFieldUpdate.ReadFrom, which allows
you to browse for a database. You can then apply these field definitions to a database at
runtime using the ApplyToFile() procedure, specifying the path to a database to which you
want
to apply the field definitions contained in TFieldUpdate.FieldItems.
