Dear Popa,

please use the below code

        SqlConnection con = new SqlConnection(@"");
        SqlCommand cmd = new SqlCommand();
        private void Form1_Load(object sender, EventArgs e)
        {
            DataTable dt = new System.Data.DataTable();
            cmd.Connection = con;
            cmd.CommandText = "select  LastName,FirstName,Title,City from dbo.Employees";
            SqlDataAdapter da = new SqlDataAdapter(cmd);
            da.Fill(dt);
            listbox1.datasource=dt;
            listbox1.databind();

        }
