Work to grab line 1 or 4 to validate sqlite3 version....

Qt Code: 
  1. QString file_get_line(QString fullFileName,int linenr)
  2. {
  3.     QString inside ="";
  4.     QFile file(fullFileName);
  5.     int countnr = 0;
  6.     if (linenr > 0) {
  7.     if (!file.open(QFile::ReadOnly | QFile::Text)) {
  8.     return inside;
  9.     }
  10.  
  11.     QTextStream in(&file);
  12.  
  13.         while (!in.atEnd()) {   ////// eben nicht am ende
  14.          ++countnr;
  15.             if (countnr == linenr) {
  16.                 inside = in.readLine(0);
  17.                 if (inside.size() > 0) {
  18.                 return inside;  
  19.                 }
  20.              break;
  21.             }
  22.         }
  23.     file.close();
  24.     }
  25. return inside;
  26. }
