Insert data into SQL Database using ASP.NET/VB.NET

Question

I have this code:

    Dim myConn As SqlConnection
    Dim cmd As SqlCommand
    Dim sqlstring, DNAME, DEXP, DCREATION, DLASTUPDATE, DCOMMENTS As String

    DNAME = TextBox1.Text
    DEXP = TextBox2.Text
    DCREATION = TextBox3.Text
    DLASTUPDATE = TextBox4.Text
    DCOMMENTS = TextBox5.Text


    myConn = New SqlConnection("Integrated Security=SSPI;Data Source=.;Initial Catalog=DOMAIN_NAME;User ID=sa;Password=***********")

    myConn.Open()

    sqlstring = " INSERT INTO ROLAND (D_NAME, D_EXPIRATION, D_CREATION, D_LASTUPDATE,D_COMMENTS) VALUES ('" + DNAME + "','" + DEXP + "','" + DCREATION + "','" + DLASTUPDATE + "','" + DCOMMENTS + "')"

    cmd = New SqlCommand(sqlstring, myConn)

    cmd.ExecuteNonQuery()

    myConn.Close()

    Response.Redirect(Request.RawUrl, True)

When I execute, it gives me this error:

Cannot open database "DOMAIN_NAME" requested by the login. The login failed.
Login failed for user 'comm-pc10\pcuser10.comm'.

and it highlights myConn.Open()

What is the problem here, any help ? I have SQLServer 2008 and a user name and pass for my database

Answer 1

You have integrated security ON, which means SQL server uses Windows authentification and therefore ignores your user and password setting. I guess your windows user does not have access to the database.

Set "Integrated security=false" to use username/password.

Answer 2

You are using Integrated Security=SSPI which is linked with window use authentication. Either you should add that user to database for remove this .

Answer 3

The problem is the connection string :

Initial Catalog = Database Name Not Domain Name

and make sure that your user id and password is correct and Data Source is the correct server address.
