TStringListAdd (Delphi)

Description

This example uses a list box and a label on a form. When the application runs, a string list object is created and three strings are added to it. The Find method searches the strings to look for a match with the string Flowers. If the string is found, all the strings in the string list are added to the list box, and the index value of the Flowers string appears in the caption of the label control.

Code

procedure TForm1.FormCreate(Sender: TObject);
var
  MyList: TStringList;
  Index: Integer;
begin
  MyList := TStringList.Create;
  try
    MyList.Add('Animals');
    MyList.Add('Flowers');
    MyList.Add('Cars');
    MyList.Sort;   { Find will only work on sorted lists. }
    if MyList.Find('Flowers', Index) then
    begin
      ListBox1.Items.AddStrings(MyList);
      Label1.Caption := 'Flowers has an index value of ' + IntToStr(Index);
    end;
  finally
    MyList.Free;
  end;
end;
