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 " ?>

           </ parameters >
         </ connectionString >
       </ connectionStrings >
     </ enterpriseLibrary.databaseSettings >

</ 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
