Re: [/HELP\] [C#][VB6] Serial Number - Valid only ONCE!

Ideas, no.
But suggestions, i'm not sure if it's good idea to validate it by ip address since they can be dynamic, it should me something unique and static like mac address ( if it's not changing )
or something like this.

Mac Address is definately the prefered alternative. Here's an example of how to grab the mac address via Visual Basic--

Changing Your MAC Address In Window XP/Vista, Linux And Mac OS X (Sometimes known as MAC spoofing) lol...

Well I have sort of Code For vB6 But I Dunno if it Works Cuz I Havn't Been On Computer Much. But It'll Have To Do With my Thread About The Auto Updater Thingy. You Can Instead Of Putting Version put like txtserial.txt Then Like Make it Delete That .. ? I Don't Really Know.

Yeah, you could jsut make it so that once the serial is used, it is deleted.

It means that if your hard drive or OS will get screwed or you simply want to reinstall your OS you would need to re-buy your software ? That's not good.

It has to be some other way.

Yeah go for a MAC address, same as LogMeIn uses, you can trial some of their extended license types (Pro, IT Pro or w/e) and if it expires you can't trial again, they record your MAC address. =P

IP's can change so that isn't the best option, same for MAC addresses but IP's change without people know it (well n00bs don't), to modify your MAC address it's likely that you know what you are doing. ;]

[What Can I Say]

Ummm....
Once they made a correct registration
You could do
(VB6)

FSO.CreateTextFile ("C:\Program Files\reg.txt").Write ("Y")

Then In Form_Load()

Private Sub Form_Load()
If FSO.FileExists ("C:\Program Files\reg.txt") = True Then
Else
frmRegistration.Show
End If

Probs a rubbish code/example but it can be used

 

[Hammad]

But that would allow the serial number to be used on multiple IP's; something I DON'T want.

It's Kinda Hard. To Make it Like IP . Unless You Give The Program Permission To Like Edit Or Something.

How about implementing ( inside the validating program ) something like no-ip. What i mean is:

• customer buy software
• register it via webby to server with his current ip
• implemented program stores his current ip,
• on next validation implemented program sends last ip and current ip
• servers checks if product is registred for previous ip if yes updates the ip

I'm not sure it it's 100 % safe, but I can't figure out anything else right now.

You want a kind of mother server running?
Would still be the safest method imo, a mother server that keeps track of your IP- and MAC-address. =]

[evill33t]

such protections in vb are laughable and cracked in under 5 minutes

 

[Hammad]

Which is why I said OR IN C#.

 

[evill33t]

in c# its uhm 8 minutes then

 

[Hammad]

Lol.
I don't need this anymore, thanks to all the people that tried to help.

Why do you edit your first post? Perhaps it could help other people with the same problem, now they have no idea what this topic was about.
