Of course, getting documentation on these properties is another matter. Let me know if
you find any.
17.4.6 The Field Object
The
Field
object represents a field (or column) in a recordset. The Fields property of the
Recordset
object returns the
Fields
collection of all
Field
objects for that recordset.
The
Field
object has but two methods,
AppendChunk
and
GetChunk
, which are used with
large text or binary fields. The reader should refer to the documentation for more on these
methods.
17.4.6.1 Properties of the Field object
Here are the properties of the
Field
object:
ActualSize and DefinedSize
The DefinedSize property is used to set the size of a field as it is defined. The
ActualSize property returns the size of the actual data stored in that field for the
current record. Thus, for example, a
String
field named
FirstName
may have
DefinedSize
25
, but if the actual data in a given record at a particular time is
"Albert"
, then the ActualSize property will return
6
.
