Delphi 動態建立控制元件，賦值，使用
uses
中定義：
type
TMyComponent = class(TComponent)
public
item1, item2, item3, item4, item5, item6: string;
constructor Create(Owner1: TComponent; s1: string); overload;
constructor Create(Owner1: TComponent; s1, s2, s3: string); overload;
constructor Create(Owner1: TComponent; s1, s2, s3, s4, s5, s6: string); overload;
end;
定義過程：
{ TMyComponent }
constructor TMyComponent.Create(Owner1: TComponent; s1: string);
begin
inherited Create(Owner1);
item1 := s1;
item2 := item1;
item3 := item1;
item4 := item1;
item5 := item1;
item6 := item1;
end;
建立控制元件：
ComboBoxLine.Items.AddObject(FieldByName('SectionName').AsString, TMyComponent.Create(Self, FieldByName('SectionDetail').AsString));
使用：
ComboBoxLine.Items.Objects[i] as TMyComponent).item1
