protected void log_Click(object sender, EventArgs e)
  {
  SqlDataSource sds = new SqlDataSource();
  sds.ConnectionString = ConfigurationManager.ConnectionStrings["master"].ToString();  sds.SelectParameters.Add("username", TypeCode.String, this.username.Text);
  sds.SelectParameters.Add("password", TypeCode.String, this.password.Text);
  sds.SelectCommand = "SELECT * FROM [myTb] WHERE [username] = @username AND [password] = @password"; 
  DataView dv = (DataView)sds.Select(DataSourceSelectArguments.Empty);
  try
  {
  if (dv.Count == 0)
  {
  this.lblinfo.ForeColor = System.Drawing.Color.Red;
  this.lblinfo.Text = "Invalid username and password!";
  return;
  }

  FormsAuthentication.RedirectFromLoginPage(username.Text, true);
  Response.Redirect("~/English/Visual.aspx");
