Retrieve Hard Disk Serial Number or othe unique PC identifier - XP & 2KOk - I have given up on trying to find the active IP address for a given PC.
For licensing purposes I need to retrive a unique identifier from the PC that the program is installed on. The Hard disk serial number would do fine, but on Googling it seems that some of the sample code will now laways work on W2K, and not without administrator rights. Hence my question - how can I consistently get a UNIQUE PC identifier using vb.net 2003 - not bothered what the idnetifier is providing that it works 100% of the time on XP and W2K. Best wishes Paul Paul,
This is often asked although to get the harddisk serial number is as easy as all serial numbers don't have all hard disk serial numbers. The same is for processor numbers. In fact there is not one hard address on the computer you surely can test beside maybe the Mac address of a network adapter. Be aware that your approach can lead that clients turning away from you, because they are completely 24 hours 7 days a week depending from you or your helpdesk, who surely should be done by professionals (expensive persons). If not you can be bailed for high amounts of money if there goes something wrong, and in this case not only in the USA.

USB dongles
are small and quite cheap these days. Of course it all depends on the value of each sale for your software. If it's expensive, it obviously won't be worth it.

It may be
possible, for example, to generate a unique identification key for the machine, say based on a few different factors like the MAC address, the machine name, and the capacity of the C: hard drive, then use some simple obfuscation method to hide how you did it, store the key in the registry if needed, and send a copy to yourself so you have it on record. That may prove to be a relatively cheap, effective way to "lock down" licensing issues. For the "authorisation" component you could have the software require a counter-key that comes from you. Use something like public / private key pairs, or Diffie Hellman, and then let the client install validate itself based on the response. With Diffie Hellman, the agreed key could be sent back with the "public" part of your half of the authorisation, which also serves to make the authorisation key nice and long. This should be able to be coded quite easily with a little time. There are plenty of maths libraries available to do the number crunching for you. I hope that this helps Cheers The Frog Try this
Dim mo As New ManagementObjectSearcher( _ "root\CIMV2", _ "SELECT * FROM Win32_NetworkAdapterConfiguration") For Each mac As ManagementObject In mo.Get() Debug.WriteLine("MACAddress: " & CType(mac("MACAddress"), String)) Next Show quoteHide quote "The Frog" <andrew.hogend***@eu.effem.com> wrote in message news:1165827331.238903.293380@j72g2000cwa.googlegroups.com... > Have you considered using a cryptographic type approach?

in this case the program would only fail if the harddiks is replaced in the system http://www.winsim.com/diskid32/diskid32.html regards Michel Show quoteHide quote "Paul Bromley" wrote: > Ok - I have given up on trying to find the active IP address for a given PC. > For licensing purposes I need to retrive a unique identifier from the PC > that the program is installed on.

The GetDiskSerial.DLL is a standard 32-bit DLL file.You can use it to read the serial number of hard disk easily. As we all know, this serial number is unique in the world. So this DLL is of great use, for example, you can use this serial number to creat an encrypt number. Key Features *Easy to obtain the serial number of hard disk. *Support reading several physics hard disks. *Many development languages are supported, such as the Delphi, C++Builder, VC, C#, VB, VB.NET, PowerBuilder, Visual Foxpro, Clarion etc is available. *Read more parameters, such as Model Number, Revision Number, Buffer Size, Cylinders, Heads, Sectors per track, etc. *Not require administrator rights in Win NT/2000/XP. Product Sheet: http://www.devlib.net/getdiskserial.htm Trials are available at http://www.devlib.net/download/getdiskserial.zip For more information, please visit http://www.devlib.net "Paul Bromley дµÀ£º " Show quoteHide quote > Ok - I have given up on trying to find the active IP address for a given PC. > For licensing purposes I need to retrive a unique identifier from the PC > that the program is installed on.
