Hej E.

Jeg har nedenstående kode:
Men der kommer en fejl når jeg prøvet at åbne min connection.
(se her: http://www.dotdk.dk/exp/error.asp)

Er der en som kan hjælpe mig videre.

Jeg har prøvet med :
SqlConnection("server=(local);database=pubs;uid=;pwd=")
Da jeg burger windows logon til at logge på sql databasen.


Imports System.Data
Imports System.Data.SqlClient

Public Class Form1
    Inherits System.Windows.Forms.Form


    Dim myConnection As SqlConnection = New _
    SqlConnection("server=(local);database=pubs;uid=jakob;pwd=jakob")
    Dim myDataAdapter As New SqlDataAdapter()
    Dim myDataSet As DataSet = New DataSet()


    Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
        'set the selectcommand properties...
        myDataAdapter.SelectCommand = New SqlCommand()
        myDataAdapter.SelectCommand.Connection = myConnection
        myDataAdapter.SelectCommand.CommandText = _
        "Select au_lname, au_fname, title, price" & _
        "From authors " & _
        "Join titleauthor on authors.au_id = titleauthor.au_id " & _
        "Join titles on titleauthor.title_id = titles.title_id " & _
        "Order By au_lname, au_fname"
        myDataAdapter.SelectCommand.CommandType = CommandType.Text

        'Open the connection
        myConnection.Open()
        'now execute the command
        myDataAdapter.SelectCommand.ExecuteNonQuery()
        'Fill the dataset object with data
        myDataAdapter.Fill(myDataSet, "Authors")
        'lukker igen
        myConnection.Close()
        grdAuthorTitles.DataSource = myDataSet
        grdAuthorTitles.DataMember = "authors"



    End Sub
End Class
