ASP.NET中自定义提示对话框

1.在需要的地方调用下面的方法：
CommonScript.MessageBox("100006",this) ; 
 
2.上面用到的CommonScript类里的MessageBox方法：
public static void MessageBox(string str_ErrCode, Page page)
            { 
                  IDataReader ErrMsg= DatabaseAccess.executeDataReader("ImportAndExport","Select ErrMessage from ErrMessage where ErrCode='" + str_ErrCode + "'");
                  while (ErrMsg.Read())
                  {
                        String ErrMessage=ErrMsg["ErrMessage"].ToString();
                        page.RegisterStartupScript("","<script>alert('"+ ErrMessage +"');</script>");
                        break ;
                  }
            }
 
3. 上面用到的DatabaseAccess类里的executeDataReader方法
public static IDataReader executeDataReader(String connectionString, String Sqlstr )
            { 
                  Database db= DatabaseFactory.CreateDatabase(connectionString);
                  IDataReader dr;
                  DBCommandWrapper wrap = db.GetSqlStringCommandWrapper(Sqlstr);
                  dr=db.ExecuteReader(wrap);
                  return dr;
            }
 
4.上面用到的连接串ImportAndExport在dataconfiguration.config里的内容(粗体部分)：
<?xmlversion="1.0"encoding="utf-8"?>
<dataConfiguration>

5．数据库：
if exists (select * from dbo.sysobjects where id = object_id(N'[dbo].[ErrMessage]') and OBJECTPROPERTY(id, N'IsUserTable') = 1)
drop table [dbo].[ErrMessage]
GO
 
CREATE TABLE [dbo].[ErrMessage] (
      [ErrID] [int] NOT NULL ,
      [ErrCode] [varchar] (50) COLLATE SQL_Latin1_General_CP1_CI_AS NOT NULL ,
      [ErrModul] [varchar] (50) COLLATE SQL_Latin1_General_CP1_CI_AS NULL ,
      [ErrSubModul] [varchar] (50) COLLATE SQL_Latin1_General_CP1_CI_AS NULL ,
      [ErrMessage] [nvarchar] (200) COLLATE SQL_Latin1_General_CP1_CI_AS NOT NULL 
) ON [PRIMARY]
GO
