Writing to a file

Message 1 in thread

I am trying to write the info stored in a variable to a file.  How do I
get Qt to write the value stored in the variable instead of the memory
address of the variable to the file?
 
Thanks,
Roger

Does that work:

  int   value = 42;
  QFile file ("c:\\temp\\test.txt");

  if (file.open (QIODevice::WriteOnly | QIODevice::Text) == true) {
    QTextStream out (&file);
    out << "My value: " << value << "\n";
    file.close();
  }

Cheers, Oliver

Make sure you dereference your variable.  Your probably sending the
address to the stream, rather then the value.
