Implements a virtual method for positioning the cursor on the last record in a filtered dataset.
function FindLast: Boolean;
This function returns False, indicating that the cursor was not successfully repositioned.
Descendant classes override FindLast to position the cursor on the last record of the dataset,
honoring any filters that are in effect. FindLast should return True if the cursor is
|Delphi 7 and prior has poor support for int64 values in variant type. This means
that you'll be unable to use Locate() and similar methods with such fields. Lookup fields and
master-detail tables will not work properly too because of their dependence on Locate() method.
Please update your IDE to BDS 2006 (or later) or don't use BIGINT and UNSIGNED INT datatypes
for keys and indexes if you need to use them in lookup fields. Also you can't use variant-style
properties (FieldValues, AsVariant and so on) with such fields.|
