pcsoft.us.windevCopyright 2026, PC SOFT24 Apr 2015 00:19:43 Z26 Mar 2014 16:05:00 ZHi folks! I am deriving the machine's harddisk-ID through this function: gsComputerID is string = fDriveInfo("C:", fdSerialNumber) The context this is used is locking down an app by issuing an activation code which is based on the machines harddisk ID. When I run the above code I get two absolutely identical H/D-ID's!! :confused: My development takes place on two identical machines running Win 7 Pro 32 Bit, one having been created by cloning the other <- and I guess that this is at the root of the problem? I am aware of the fact that the coded function uses an ID which is created at formatting the drive. It seems not to be the s/n given by the manufacturer of the drive. So when using a cloned workstation, we can therefore not use the above code to obtain a really unique machine ID since one is cloning the 'formatted ID' (in lack of a better word) as well (e.g. whenever I set up a new workstation in a network, I do so by cloning a 'default' disk and hence end up having a whole network consisting of workstations with the same H/D-ID and thus preventing me from using a machine based activation scheme ..). My question then: How could I get at the H/D-ID as supplied by the manufacturer of the disk - this number would be unique for all practical purposes, OK? Unforunately, I haven't found a solution by browsing the help... Thanks for your thoughts!30WEBDEVen_UShttps://forum.pcsoft.fr/es-ES/pcsoft.us.windev/45214-18-two-machines-with-identical/read.awpmoderateur@pcsoft.fr (El moderador)webmaster@pcsoft.fr (El webmaster)fempcsoft.us.windevhttps://forum.pcsoft.fr/es-ES/pcsoft.us.windev/45214-18-two-machines-with-identical-51761/read.awp24 Apr 2015 00:19:43 ZCharles...
