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)

3. 上面用到的DatabaseAccess类里的executeDataReader方法
public static IDataReader executeDataReader(String connectionString, String Sqlstr )

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"?>

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
