楼上的说的真够清楚，真是个好同志:)

sa账号密码错误，更改一下试试

可能要修改一下你的web.config文件的数据库连接字符串的，比如你的sa账号密码对不对得上

把add name=&quot;pn163ConnectionString2&quot; connectionString=&quot;Data Source=.;Initial Catalog=pn163;User ID=sa;Password=sa&quot;<br/>27&nbsp;&nbsp; providerName=&quot;System.Data.SqlClient&quot; /&gt;<br/><br/>你的数据库连接时候的用户名是什么?比如是sa.&quot; User ID=sa&quot;&nbsp;&nbsp;这里就是sa.<br/>你连接数据库时候的密码是多少?比如是sa&quot;Password=sa&quot;这里就是sa.如果你的密码是100,<br/>那么这里就是Password=100<br/><br/>明白了吗?

下了，运行起来就这样，请高手指教:'( :'( :'( <br/><br/><br/>“/”应用程序中的服务器错误。<br/>--------------------------------------------------------------------------------<br/><br/>用户 'sa' 登录失败。 <br/>说明: 执行当前 Web 请求期间，出现未处理的异常。请检查堆栈跟踪信息，以了解有关该错误以及代码中导致错误的出处的详细信息。 <br/><br/>异常详细信息: System.Data.SqlClient.SqlException: 用户 'sa' 登录失败。<br/><br/>源错误: <br/><br/><br/>行 23:&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; DataSet Ds1 = new DataSet();<br/>行 24: <br/>行 25:&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; Da1.Fill(Ds1, &quot;NewView&quot;);<br/>行 26: <br/>行 27:&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; PagedDataSource Pds = new PagedDataSource();<br/> <br/><br/>源文件: c:\Documents and Settings\Administrator\桌面\ScNIC\Default.aspx.cs&nbsp;&nbsp;&nbsp;&nbsp;行: 25 <br/><br/>堆栈跟踪: <br/><br/><br/>[SqlException (0x80131904): 用户 'sa' 登录失败。]<br/>&nbsp;&nbsp; System.Data.ProviderBase.DbConnectionPool.GetConnection(DbConnection owningObject) +437<br/>&nbsp;&nbsp; System.Data.ProviderBase.DbConnectionFactory.GetConnection(DbConnection owningConnection) +82<br/>&nbsp;&nbsp; System.Data.ProviderBase.DbConnectionClosed.OpenConnection(DbConnection outerConnection, DbConnectionFactory connectionFactory) +105<br/>&nbsp;&nbsp; System.Data.SqlClient.SqlConnection.Open() +111<br/>&nbsp;&nbsp; System.Data.Common.DbDataAdapter.FillInternal(DataSet dataset, DataTable[] datatables, Int32 startRecord, Int32 maxRecords, String srcTable, IDbCommand command, CommandBehavior behavior) +121<br/>&nbsp;&nbsp; System.Data.Common.DbDataAdapter.Fill(DataSet dataSet, Int32 startRecord, Int32 maxRecords, String srcTable, IDbCommand command, CommandBehavior behavior) +137<br/>&nbsp;&nbsp; System.Data.Common.DbDataAdapter.Fill(DataSet dataSet, String srcTable) +83<br/>&nbsp;&nbsp; _Default.Page_Load(Object sender, EventArgs e) in c:\Documents and Settings\Administrator\桌面\ScNIC\Default.aspx.cs:25<br/>&nbsp;&nbsp; System.Web.Util.CalliHelper.EventArgFunctionCaller(IntPtr fp, Object o, Object t, EventArgs e) +15<br/>&nbsp;&nbsp; System.Web.Util.CalliEventHandlerDelegateProxy.Callback(Object sender, EventArgs e) +34<br/>&nbsp;&nbsp; System.Web.UI.Control.OnLoad(EventArgs e) +99<br/>&nbsp;&nbsp; System.Web.UI.Control.LoadRecursive() +47<br/>&nbsp;&nbsp; System.Web.UI.Page.ProcessRequestMain(Boolean includeStagesBeforeAsyncPoint, Boolean includeStagesAfterAsyncPoint) +1061<br/><br/> <br/><br/><br/>--------------------------------------------------------------------------------<br/>版本信息: Microsoft .NET Framework 版本:2.0.50727.42; ASP.NET 版本:2.0.50727.42
