  TForm2 = class(TForm)
    ADOQuery1: TADOQuery;
    DataSource1: TDataSource;
    DBGrid1: TDBGrid;
    BitBtn1: TBitBtn;
    DBEdit1: TDBEdit;
    DBEdit2: TDBEdit;
    Label1: TLabel;
    Label2: TLabel;
    BitBtn2: TBitBtn;
    procedure FormCreate(Sender: TObject);
    procedure BitBtn1Click(Sender: TObject);
    procedure BitBtn2Click(Sender: TObject);
    procedure FormClose(Sender: TObject; var Action: TCloseAction);
  private

uses Unit1;   //引用主界面

{$R *.dfm}

procedure TForm2.FormCreate(Sender: TObject);

    if not adoquery1.Active then adoquery1.Open;
end;

procedure TForm2.BitBtn1Click(Sender: TObject);
begin
    adoquery1.Insert;

procedure TForm2.BitBtn2Click(Sender: TObject);
begin
    With AdoQuery1 do
    Try
        If State in [dsEdit,dsInsert] then Post;
