PROBLEM：ASP.NET 和SQL SERVER

henhen(哼哼~~,找工ing~~~~)

WINDOWS XP,SQL2000,.NET问题：
SQL用MIX authentication，如果是standard type用户xxx，
string connectionString="server=localhost;uid=xxx;pwd=1234;database=northwind";
string commandString="select * from Customers";
SqlDataAdapter dataAdapter=new SqlDataAdapter(commandString,connectionString);
上述C#代码完全OK，但是如果是XP的用户YYY，没有password，而且进XP是用YYY登陆的，怎么写connectionString？试了大半天不行，但是可以直接用当前连接在SQL Enquiry查询，也能在form上加一个dataadapter控件测试直接用windows连接到数据库OK。

谢谢！ email: henhen001@yahoo.com

try trust connection. Windows user can login to SQL Server automatically if it set to trust connection -ludouya(绿豆牙); 2002-7-20 (#646885@0)

谢谢，总算可以中文了。 -henhen(哼哼~~,找工ing~~~~); 2002-7-20 {102} (#647261@0)
it said lack of true connection.But I don't know how to set up,could you give me more details?Thanks.

then whats the error msg? -bigdesk(nothing); 2002-7-20 (#647239@0)

excuse me,I can't remember although I saw it many many times.it seems: -henhen(哼哼~~,找工ing~~~~); 2002-7-20 {123} (#647257@0)
login failed .....user "localhost\xxxx", not associate with any trust connection.
when it forward next to do enquiry.

没有必要使用这种连接方法。因为ASP是在用户登录之前就已经在运行了。asp.NET使用一个叫"ASPNET"的用户名，可以使用信任连接，ASP.NET访问数据库就会使用这个LOGIN, 应在数据库内配置这个用户的权限 -miketany(MIKE老狼); 2002-7-20 (#647275@0)

谢谢，我以为还这个用户不用设置呢。:-) -henhen(哼哼~~,找工ing~~~~); 2002-7-20 (#647304@0)

OK了，加了ASPNET用户，昨天用了Integrated Security 的，就是没在SQL SERVER中设。跟大家报告一下结果，以后有问题再问。 :-) -henhen(哼哼~~,找工ing~~~~); 2002-7-20 (#647315@0)

这儿概念有点混淆. 1.you can't use the XP login ID to specify the conectionstring with sql server if you want to use non-trusted connection since the user info in the conectionstring is from sql authentication. -yangn(Raymond); 2002-7-20 {198} (#647291@0)
2. To use the trusted connection, u have to add that user to the sql server security via windows authentication under the specific domain and set "tursted_connection=YES" in your connectionstring.

Thanks very much,我就是没找到你说的那句，再次感谢大家~~~ ^o* -henhen(哼哼~~,找工ing~~~~); 2002-7-20 (#647307@0)
