Login Failed For The User (using Windows Integrated Security)

Hello Everyone,

I am trying to connect SQL database through code but I get this error,I have spent days to solve it but unfortunately I couldn't...Here is my code in VB express(OP:windows 2000 with SP4)I am new to VB,so it makes the situation more difficult for me.

my code is:

Public Class Form1



Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load

Dim conn1 As SqlConnection = _

New SqlConnection("Data Source=.SQLEXPRESS;" & _

"Integrated Security=SSPI;" & _

"database=deneme3_database;")

'Open connection

conn1.Open()

MessageBox.Show("Connection succeeded.")

'Close connection

conn1.Close()

MessageBox.Show("Connection closed.")

End Sub



The error message is,it is in german but it is clear I guess:)

" Die von der Anmeldung angeforderte "deneme3_database"-Datenbank kann nicht geöffnet werden. Fehler bei der Anmeldung.
Fehler bei der Anmeldung für den Benutzer 'ADPLANatalay'. "





Thank you in advance!
