How to send Server response in cakephp -


I have tried the following in the App Controller of the filter, it does not seem to be 

  $ This- & gt; Feedback & gt; StatusCode (404);

or 

  header ('HTTP / 1.1 404 unauthorized', true, 404); Header ('HTTP / 1.1 404 not found');

or 

  throw the new NotFoundException ();

If I debug the response, the status is shown as 404, but the HTTP status checker is always 200. I do not know why

the solution Found 

  if (! Function_exists ('http_response_code')) {function http_response_code ($ newcode = NULL) {static $ code = 200; If ($ newcode! == faucet) {Header ('x-php-answer-code:'. $ New code, true, $ newcode); If (! Headers_sent ()) $ code = $ newcode; } return code; }}

c# - Showing a SelectedItem's Property -

So I have enabled a rightclick option for my DataGrid. I want to display the only chosen property but it is not behaving like what I would like it to display my name and additional. Public category Paymentinfo {public int PaymentNo {get; Set; } Public string date {get; Set; } Public Double Pay {get; Set; } Public Double Principle {get; Set; } Public Double Interest {get; Set; } Public Double Balance {Received; Set; }} Private Zero MenuItem_OnClick (Object Sender, RoutedEventArgs e) {MessageBox.Show (AmortGrid.SelectedItem.ToString ()); } I'm trying to apply it without using a View Module! If I place a breakpoint where the messagebox and the recipient place it on selected ITEM, then this property will display the payment.
