File permission QFile::WriteOther on Win Dos

If I copy a resource file to a tmp cache dir... so...
MoveAndCopy(QString::fromUtf8(":/images/images/master.sql"),STATIC_TMP_SQL_DUMP);

after this file is readonly to user....
How i set write and remove from application? and edit from user?

Code:

---

bool Gui_Front::MoveAndCopy(QString file, QString destfile) 
{
       QFile Image(file);
       if (db->is_file(destfile)) {
          db->qt_unlink(destfile); 
       }
      if (!Image.copy(destfile)) {
        /*QMessageBox::warning( this,tr( "File Error!" ) , tr("Unable to copy a file to.. %1").arg( destfile ));*/
        return false;
       } else {
        QFile Image2(destfile);
        Image2.setPermissions(QFile::WriteOther);  /* all 0777 */
        return true;
       }
}

I dont have Qt here so I can't try it, but I think you need to set all the permissions something like this:

Code:

---

Image2.setPermissions(QFile::ReadOwner | QFile::WriteOwner |
                      QFile::ReadUser  | QFile::WriteUser  | QFile::ReadGroup |
                      QFile::WriteGroup | QFile::ReadOther | QFile::WriteOther);  /* all 0777 */
