//添加数据和对象到下拉框
procedure TForm1.Button1Click(Sender: TObject);
var
s:string;
begin
ComboBox1.Items.Clear;
s:= '1001';
//ComboBox1.Items.Add('1');
ComboBox1.Items.AddObject('1',TObject(s) );
s:='2001';
//ComboBox1.Items.Add('2');
ComboBox1.Items.AddObject('2',TObject(s) );
s:='3001';
//ComboBox1.Items.Add('3');
