Hi,
There is a file including varies type of data. data is written in this file as below:
1- 500 doubles
2- 500 doubles
3- 500 doubles
4- 500 ints
5- 500 QString inside a QStringList

and the code for writing this file is:
Qt Code: 
  1. void write()
  2. {
  3.     QFile g1f, g2f, of, chf, namef;
  4.     double g1[500];
  5.     double g2[500];
  6.     double ofse[500];
  7.     int ch[500];
  8.     QStringList names;
  9.     for(int i=0; i<500; ++i)
  10.     {
  11.         g1[i] = i/2.0;
  12.         g2[i] = 2.0*i;
  13.         ofse[i] = 1;
  14.         ch[i]=i;
  15.         names.append(QString("name%1").arg(i));
  16.     }
  17.  
  18.     g1f.setFileName("oneFile.th");
  19.     if(!g1f.open(QFile::WriteOnly))
  20.     {
  21.         qDebug()<<"can not open to write";
  22.     }
  23.     g1f.write((char*)g1, (500)*sizeof(double));
  24.     g1f.flush();
  25.     g1f.close();
  26.  
  27.     g2f.setFileName("oneFile.th");
  28.     if(!g2f.open(QFile::Append))
  29.     {
  30.         qDebug()<<"can not open to write";
  31.     }
  32.     g2f.write((char*)g2, (500)*sizeof(double));
  33.     g2f.flush();
  34.     g2f.close();
  35.  
  36.  
  37.     of.setFileName("oneFile.th");
  38.     if(!of.open(QFile::Append))
  39.     {
  40.         qDebug()<<"can not open to write";
  41.     }
  42.     of.write((char*)ofse, (500)*sizeof(double));
  43.     of.flush();
  44.     of.close();
  45.  
  46.     chf.setFileName("oneFile.th");
  47.     if(!chf.open(QFile::Append))
  48.     {
  49.         qDebug()<<"can not open to write";
  50.     }
  51.     chf.write((char*)ch, (500)*sizeof(int));
  52.     chf.flush();
  53.     chf.close();
  54.  
  55.     namef.setFileName("oneFile.th");
  56.     if(!namef.open(QFile::Append))
  57.     {
  58.         qDebug()<<"can not open to write";
  59.     }
  60.     QDataStream df(&namef);
  61.     df << names;
  62.     namef.flush();
  63.     namef.close();
  64. }
To copy to clipboard, switch view to plain text mode 

now i want to read this file and separate to:
1- 500 doubles >>>>> double ge1[500]
2- 500 doubles >>>>> double ge2[500]
3- 500 doubles >>>>> double of[500]
4- 500 ints >>>>> int ch[500]
5- 500 QString inside a QStringList >>>>> QStringList nam

please help me to read and separate this file.

thanks
