利用TDatabase组件去掉登陆对话框

这个例子要注意建立数据源（.mdb）,还有就是使用table组件的tablename属性

unit Unit1;

interface

uses
  Windows, Messages, SysUtils, Variants, Classes, Graphics, Controls, Forms,
  Dialogs, DB, DBTables, Grids, DBGrids;

type
  TForm1 = class(TForm)
    DBGrid1: TDBGrid;
    Table1: TTable;
    DataSource1: TDataSource;
    Database1: TDatabase;
    procedure FormCreate(Sender: TObject);
  private
    { Private declarations }
  public
    { Public declarations }
  end;

var
  Form1: TForm1;

implementation

{$R *.dfm}

procedure TForm1.FormCreate(Sender: TObject);
begin
  Database1.Params.Add('username=sa');
  Database1.Params.Add('password=');
  Database1.LoginPrompt:=False;       //不显示登陆对话框
  Database1.DatabaseName:='QP';
  Database1.AliasName:='QP';
  TABLE1. ACTIVE:=TRUE;
end;

end.
