Main page -> Midware component reference -> TMWBuffer -> Fields
Definition
property Fields[nIndex:Integer]: String;
Description
The indexed Fields[] property gives access to the current record's fields. Fields are numbered starting from 0 up to FieldCount - 1. Fields property always returns data as a string. For blobs, use GetStreamField. See also FieldSize and FieldType.
Existing fields can be written by assigning Fields[]. The current value is replaced by new data. To add more fields, use AppendFields or WriteFields.
Example
<syntaxhighlight lang="delphi"> procedure TForm1.Button1Click(Sender: TObject); var
Fld, Last : Integer;
begin
Last := MWBuffer1.FieldCount - 1;
for Fld := 0 to Last do
Memo1.Lines.Add(MWBuffer1.Fields[Fld]);
end; </syntaxhighlight>
