Hello
Could somebody help me?
I want to protect my application. For that I want to use a key starting from the number of the mother card.
Can how be recovered the job number of a mother card ?
Even question for the hard disk. But I believe that for the hard disk, with each formatting the number changes!
Afflicted for my English, who should not be good
, but I am French
Thank you for your assistance

i don't think there is something like a motherboard id.
you could also use the hardware id of a network card (if installed) called the MAC-Address, but though it should be unique there are tools to change that either. the only way to have a completely save and unchangeable id is to use the cpu id, which will only work for Pentium3 processors. maybe for pentium 4 as well, but i don't know about that. AMDs don't have identifieres as far as i know.
imho, the best target is the hard disk id.

Hi,
This snippet gives you the ID of the HD.
Code: Select all
appdir$=Space(255) : GetCurrentDirectory_(255,@appdir$)
DIR$ = Mid(appdir$,1,3)
lpRootPathName.s=DIR$
pVolumeNameBuffer.s=Space(256)
nVolumeNameSize=256
lpVolumeSerialNumber.i
lpMaximumComponentLength.i
lpFileSystemFlags.i
lpFileSystemNameBuffer.s=Space(256)
nFileSystemNameSize=256
Result=GetVolumeInformation_(lpRootPathName,pVolumeNameBuffer,256,@lpVolumeSerialNumber,@lpMaximumComponentLength,@lpFileSystemFlags,lpFileSystemNameBuffer,256)
ID$ = Hex(lpVolumeSerialNumber);Here is the ID of the HD
Debug ID$
Of course you need to 'hide' that you are using the ID of the HD and do something more to the ID, otherwise anyone can make a keygenerator for your application easy.
Best Regards

Change the first line from

to
Code: Select all
appdir.s=Space(255) : GetCurrentDirectory_(255,@appdir)
and it will work without error messages.
Have a nice day...
