我刚学Dreamweaver，用asp.net和数据库建了一个动态页面，测试服务器和与数据库的连接都建好了，在设计过程中点工具栏中的“查看--动态数据”也可以正常显示记录集，但是为什么我点预览和通过网站浏览时，页面上却不能正常浏览 显示如下内容：


System.Data.OleDb.OleDbException: ??????
at System.Data.OleDb.OleDbConnectionInternal..ctor(OleDbConnectionString constr, OleDbConnection connection)
at System.Data.OleDb.OleDbConnectionFactory.CreateConnection(DbConnectionOptions options, Object poolGroupProviderInfo, DbConnectionPool pool, DbConnection owningObject)
at System.Data.ProviderBase.DbConnectionFactory.CreateNonPooledConnection(DbConnection owningConnection, DbConnectionPoolGroup poolGroup)
at System.Data.ProviderBase.DbConnectionFactory.GetConnection(DbConnection owningConnection)
at System.Data.ProviderBase.DbConnectionClosed.OpenConnection(DbConnection outerConnection, DbConnectionFactory connectionFactory)
at System.Data.OleDb.OleDbConnection.Open()
at DreamweaverCtrls.DataSet.DoInit()
--------------------------------------------------------------------------------
System.Exception: The DefaultView was requested but no tables yet exist.
at DreamweaverCtrls.DataSet.get_DefaultView()

前辈们帮我看看好吗？
