This Error drives me crazy

The person running the app doesn't have permissions to the SQL database and your connection string mentions Trusted Connection.

Either change the connection string to remove Trusted Connection and supply a valid username and password to the database or add the userId to the database's Security (domain-based networks only!)

I would HIGHLY suggest reading up on SQL Server security before proceeding though...

Guy's I've this code

Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
       Dim cnStrBuilder As New SqlConnectionStringBuilder()
       cnStrBuilder.InitialCatalog = "FirstSQLDB"
       cnStrBuilder.DataSource = "WIN-H08I7LJ7JEA\SQLEXPRESS"
       cnStrBuilder.ConnectTimeout = 30
       Dim cn As New SqlConnection()
       cn.ConnectionString = cnStrBuilder.ConnectionString
       cn.Open()
       Dim strSQL As String = "Select * From Employee_Info"
       Dim myCommand As New SqlCommand(strSQL, cn)
       Dim reader As SqlDataReader = myCommand.ExecuteReader(CommandBehavior.CloseConnection)
       TextBox1.Text = reader(1).ToString()
   End Sub

Evey tome I run it, I got the same error
"Login failed for user ''. The user is not associated with a trusted SQL Server connection."

I did a lot of things but i doesn't work
