          DataGridView.DataSource = dataSet.Tables("Table").DefaultView
        Catch Ex As Exception
          MsgBox(Err.Description)
        Finally
          dataSet.Dispose
          DataAdapter.Dispose
          dbConnection.Close
          dbConnection.Dispose
        End Try

  End Sub

PS：
Access数据库文件，可以通过 My Project -> 资源 -> 添加资源 -> 添加python基础教程现有文件 这样的方式来添加
调试状态下，每次运行项目，Resources下面的数据库将会覆盖Debug下的数据库
