iam using windows authentication in the project so sql username and password are not involved....
I tried ur idea of connection string and mah problem is almost solved..but still an exception is gettin occured.
i guess dis tym der is a problem in mah code.
so following is mah code:

Dim constr As String
             constr = "Data Source=YOGESH\SQLEXPRESS;Initial Catalog=projdb;Integrated Security=True"
        Dim conn As New SqlConnection(constr)
        Dim cmd As New SqlCommand(constr, conn)
        Dim rd As SqlDataReader
        cmd.CommandText = "select * from employee where emp_name='txtname.text'"

            rd = cmd.ExecuteReader()
            GridView1.DataSource = rd
        Catch ex As Exception
            MsgBox("exception occured:", MsgBoxStyle.Critical)
            MsgBox.show(ex.Message, MsgBoxStyle.Critical)

        End Try

basicallly iam tryin to fetch the details of the employee whose name is entered in the textbox of the form from the database and display the same in a gridview
so after entering the name when i click the submit button an exception stating"exception occured" is gettin displayed..
plzzzzz suggest the changes..

thanxx for ur reply.

An exception of type 'System.Data.SqlClient.SqlException' occurred in System.Data.dll but was not handled in user code

Additional information: Login failed for user ''. The user is not associated with a trusted SQL Server connection.
