When I calculate the integer representation of the hard disk serial number on my Windows7 64 bit PC with File::getVolumeSerialNumber(), I get a negative number for the C drive (when running the executable from e.g. the desktop and using currentApplicationFile for the file location). It works well on the D drive and on a USB stick (i.e. the identifiers are the same there when converted to hex as the ones I get with the DOS ‘vol’ command). Any ideas?
Ah, got it. When the integer representation is negative you have to multiply it with -1, convert to hex and subtract the result from ffffffff to get the corresponding ‘vol’ result.
…or just cast it to an unsigned int!
Rrright… thanks!
What about the Mac side? Whatever special location I choose I always get back 0 for the VolumeSerialNumber… which is not surprising since
int File::getVolumeSerialNumber() const
{
return 0; // xxx
}
is what is written in juce_posix_shared_Code.h … is this a Windows thing only?
That’s right, only win32 provides a way of getting that value AFAIK
No, that’s wrong.
I’ve a code running on linux that does this, I’ve sent to you by email (to big to be pasted here).
No idea how it works on Mac.
