Hi, I try to write a blob to a file and then execute it. My code:
source:
Qt Code: 
  1. ProgramLauncher::ProgramLauncher ( QObject *parent )
  2. 		: QObject ( parent )
  3. {
  4. 	loader = new BinaryLoader ( );
  5. 	connect ( loader, SIGNAL ( dataLoaded ( int, QByteArray ) ), this, SLOT ( loaded ( int, QByteArray ) ) );
  6. }
  7.  
  8. void ProgramLauncher::launch ( int id )
  9. {
  10. 	qDebug() << id;
  11. 	loader->getData ( "bin_programs", id );
  12. }
  13.  
  14. void ProgramLauncher::loaded ( int handle, QByteArray data )
  15. {
  16. 	Q_UNUSED ( handle );
  17. // 	QString path = QDir::tempPath() + "XXXXXX";
  18. 	QTemporaryFile *tmpFile = new QTemporaryFile ( QString ( "XXXXXX" ) );
  19. 	if ( !tmpFile->open ( ) )
  20. 	{
  21. 		return;
  22. 	}
  23. 	qDebug() << "tmpFile: " << tmpFile->fileName() << " opened";
  24. 	qint64 size = tmpFile->write ( data );
  25. 	if ( size != -1 )
  26. 	{
  27. 		qDebug() << "wrote " << size << " into the file";
  28. 		execute ( tmpFile );
  29. 	}
  30. }
  31.  
  32. void ProgramLauncher::execute ( QTemporaryFile *file )
  33. {
  34. 	QString path = QDir::tempPath() + "/" + file->fileName();
  35. 	qDebug() << "Launching filename " << path;
  36. 	qDebug() << QProcess::startDetached ( path );
  37. }
  38. ProgramLauncher::~ProgramLauncher()
  39. {
  40. }

header:
Qt Code: 
  1. class ProgramLauncher : public QObject
  2. {
  3. 		Q_OBJECT
  4. 	public:
  5. 		ProgramLauncher ( QObject *parent = 0 );
  6. 		~ProgramLauncher();
  7. 	public slots:
  8. 		void launch ( int id );
  9. 		void loaded ( int handle, QByteArray data );
  10. 	private:
  11. 		void execute ( QTemporaryFile *file );
  12. 		BinaryLoader *loader;
  13. };

My problem is that it doesn't create the file where it should. According to the doc, it should be in QDir::tempPath(), but instead it is where the program was started. So, starting the binary fails cause my functions look into /tmp:
Qt Code: 
  1. 5
  2. tmpFile:  "XN1408"  opened
  3. wrote  24791336  into the file
  4. Launching filename  "/tmp/XN1408"
  5. false

Why that?

The program is developed on linux, target platform will be windows where it should run from CD (so no write access).

And: I thought the file will be removed upon destruction of the object? it stays where it is, including content
