Hello

In my Project I am creating a LogReport.txt. Which maintain a Report like below
ECU->USS
Sensor Time Data
USS1 17:45:51 0x0,0xff,0x0,0x0
USS2 17:45:52 0x0,0x0,0xff,0x0
USS3 17:45:53 0x0,0x0,0x0,0x0
USS4 17:45:54 0x0,0xff,0x0,0x0
USS->ECU
Sensor Time Data
USS1 17:45:51 0x0,0x0,0x0,0x0
USS2 17:45:52 0x0,0xff,0x0,0x0
USS3 17:45:53 0x0,0xff,0x0,0x0
USS4 17:45:54 0x0,0x0,0xff,0x0
------
------
And so on until the code run.
Now once I stop my code I have to read back same data on button click.
Suppose on first click I have to read 17:45:51 0x0 0xff 0x0 0x0 and second click 17:45:52 0x0 0x0 0xff 0x0 and so on.
Can any one let me know how can I read each line with five different column.

Writefile
Qt Code: 
  1. file->setFileName("LogReport.txt");
  2.     file->open(QIODevice::WriteOnly | QIODevice::Text);
  3. QTextStream stream(file);
  4.   int index = 0;
  5.  
  6.   stream << "ECU->USS\n";
  7.   stream <<"Sensor"<<"     "<<"Time"<<"                  "<<"Data"<<endl;
  8.   for(int i = 0;i<12;i++)
  9.   {
  10.       stream << "USS"<<i+1<<"    ";
  11.  
  12.       stream<<time_log_ecu2uss[i];
  13.       if(i<9)
  14.       {
  15.       stream<<"           ";
  16.       }
  17.       else
  18.       {
  19.       stream<<"          ";
  20.       }
  21.  
  22.       for(int j = 0;j<4;j++)
  23.       {
  24.  
  25.           stream<<("0x"+QString::number(Data_ecu2uss[index],16));
  26.           if(j<3)
  27.           {
  28.           stream<<",";
  29.           }
  30.           index++;
  31.       }
  32.  
  33.       stream<<endl;
  34.   }
  35.  
  36.   index  = 0 ;
  37.   stream << "USS->ECU\n";
  38.   stream <<"Sensor"<<"     "<<"Time"<<"                  "<<"Data"<<endl;

  43.       if(i<9)
  44.       {
  45.       stream<<"           ";
  46.       }
  47.       else
  48.       {
  49.       stream<<"          ";
  50.       }
  51.       for(int j = 0;j<4;j++)
  52.       {
  53.           stream<<("0x"+QString::number(Data_uss2ecu[index],16));
  54.           if(j<3)

  57.           }
  58.           index++;
  59.       }
  60.       stream<<endl;

  62.  
  63.   stream<<"******************************************************************"<<endl;
