      return arrSupport[section]
  }
  
  func tableView(_ tableView: UITableView, willDisplayHeaderView view:UIView, forSection: Int) {
      if let tableViewHeaderFooterView = view as? UITableViewHeaderFooterView {
          tableViewHeaderFooterView.textLabel?.textColor = UIColor.white
          tableViewHeaderFooterView.textLabel?.font = UIFont.systemFont(ofSize: 16, weight: .medium)
          tableViewHeaderFooterView.contentView.backgroundColor = UIColor(red: 39.0 / 255.0, green: 41.0 / 255.0, blue: 53.0 / 255.0, alpha: 1.0)
          let headerView = UIView()
          headerView.frame = CGRect(x: tblSupport.frame.origin.x-10, y: 10, width: tblSupport.frame.size.width-20, height: 60)
          tableViewHeaderFooterView.contentView.frame = CGRect(x: 10, y: 0, width: tableView.frame.size.width-20, height: 50)

• How to use multiple spacing in single UILabel

  I have an array of strings, I make a string from the array objects

  let stringForLabel = arrayContaingStrings.joined(separator: "\n")
  

  But when I show this it in a single UILabel, it is hard to read as below

  The 6th and 7th lines in the above label are a single line as

   Nowy Dwor Mazowiecki, Poland
  

  But due to screen width is shown in 2 lines. So I would display it in the following format

  

  How can I achieve this spacing in UIlabel? I have tried increasing line spacing in storyboard but then it increases all line spacing in the label. (The content in both images are different, I just wanted to show the line spacing in both cases)

• 2 way encryptation in PHP without PHP functions

  I am trying to do an encryptation and decryptation method in PHP. I was using openssl and other PHP functions, but I have been asked not to use any of these kind of functions for doing this because of compatibility problems. Therefore, I would like to know a way in which I can encrypt a string and decrypt it back using a key. I have found this for encrypting

  for($i=0, $k= strlen($string); $i<$k; $i++) 
          {
              $char = substr($string, $i, 1);
              $keychar = substr($key, ($i % strlen($key))-1, 1);
              $char = chr(ord($char)+ord($keychar));
              $result .= $char;
          }
          return base64_encode($result);
  

  and this for decrypting

  $string = base64_decode($string);
          for($i=0,$k=strlen($string); $i< $k ; $i++) 
          {
              $char = substr($string, $i, 1);
              $keychar = substr($key, ($i % strlen($key))-1, 1);
              $char = chr(ord($char)-ord($keychar));
              $result.=$char;
          }
  return result;
  

  But the first one doesn't seem to work, as it always returns a "1"
• Does the secret key needs to be protected using Jasypt ? If yes, how can it be done?

  I'm trying to encrypt Database password within application.properties file using Jasypt (Java Simplified Encryption) for Spring Boot application. I went through the Web and what I saw is everybody is using the secret key explicitly in the source code for decryption. This doesn't make sense because knowing this secret key and having the encrypted password we can easily decrypt the password using Jasypt CMD command.

  Does somebody know if the secret key needs to be protected using Jasypt ? If yes, how can it be done securely? Thank you very much in advance.

• Save the received MJPEG data in a .mjpeg file with C#

  I have a project. It is with Raspberry Pi Camera V2. One PC is used for encoding the captured video in MJPEG format and sending it with the serial port. My PC is used for receiving the data, saving it in a .mjpeg formatted file and playing it with an MJPEG to MP4 converter. I am trying to save the data in these lines:

  byte[] data= new byte[100];
  serialPort.Read(data,0,100);
  BinaryWriter videoFile = new BinaryWriter(File.Open("video.mjpeg",FileMode.Create));
  
  string dataAscii;
  dataAscii = System.Text.Encoding.UTF8.GetString(data); //bytearray to string
  
  videoFile.Write(dataAscii); // which is received
  

  It works, it creates a .mjpeg file. However, I couldn't make it play with the converter. Maybe I should save the data frame by frame or try to save in a different way. I have no idea about what I am doing wrong.

  Any ideas, many thanks!

• email header get filename with ehtml url encoding

  I met with the problem of parsing the filename encoded in html url encoding.

  Content-Transfer-Encoding: base64
  Content-Disposition: attachment;
   filename*0*=utf-8''%48%61%72%6D%6F%6E%6F%67%72%61%6D;
   filename*1*=%32%30%31%38%20%C5%81%75%6B%61%73%7A%65%77;
   filename*2*=%61%20%33%35%2E%70%64%66
  

  After get_filename it returns already filename decoded with extended ASCII characters. In that case decode_header can not deal with anymore. Here is exception:

    File "/usr/lib/python2.7/email/header.py", line 73, in decode_header
  header = str(header)
  UnicodeEncodeError: 'ascii' codec can't encode character u'\u0141' in position 26: ordinal not in range(128)
  

  Here is a piece of code to getting the filename:

  for part in msg.walk():
          if part.get_content_maintype() == 'multipart':
              continue
          content = part.get_payload(decode=True)
          if content:
              filename = part.get_filename()
              if filename:
                  filename = decode_header(filename)
                  [...]
  

  All other normal encoding seems to work. Could you advise me how can I resolve this?
