This code only works on the PC. #ifdef _WIN32 #declareapi GetVolumeInformation kndll GetVolumeInformation 8 1 new(vserial$, tint); GetVolumeInformation("C:\\", NULL, 0, &vserial$, NULL, NULL, NULL, 0); sprintf(serial$, "0x%4X%4X", HiWord(vserial$), LoWord(vserial$)); ShowMessage(serial$); #endif Regards, Alain Deschenes President and programmer ArianeSoft Inc.

What is the equiv DLL file on the PPC? Editor of \'Voice of the PPL\' the newsletter for the PPL by the PPL! Still trying to get people to contribute to the newsletter!  | ||

On the PPC, it is coredll.dll (no, that's not a typo - it's just redundant  ) Eric Pankoke Founder Point Of Light Software http://www.polsoftware.com/ | ||

What have I done wrong? I have searched the net on how Kernel32 functions work and thought I had it right? Cheers Editor of \'Voice of the PPL\' the newsletter for the PPL by the PPL!
