Create Serial Number

[Arne Beruldsen]

I have a windows app using vb.net 2005.

I would like to create a serial number based on a couple of characteristics
of the customers computer (computer name, HD number..etc). I don't need
anything complicated just a way to generate a 16 character number.

Is there an easy way to do this...?

Thanks

Re: Create Serial Number

Arne,

I don't see what is the problem with that. If it is based on existing
numbers than it is concatenating.

Can you explain to us what is the diffficult with this.

Be aware that it will never be a Global Unique ID. Therefore you need the
GUID and more positions.

Re: Create Seirial Number

In my applicattion, I used an encrpted string based on a number of features
of the user machine and my program. I created an encryption program to
create the encrypted string, and within the user program is the same
encryption function to check that the two strings are equal. The function I
used is below:-

Imports System.Text
Imports System.Security .Cryptography
Module modEncrypt
Public Function HashData(ByVal s As String) As String
'Convert the string to a byte array
Dim bytDataToHash As Byte() = _
(New UnicodeEncoding ()).GetBytes(s)
'Compute the MD5 hash algorithm
Dim bytHashValue As Byte() = _
New MD5CryptoServic eProvider().Com puteHash(bytDat aToHash)
Return BitConverter.To String(bytHashV alue)
End Function
End Module

Best wishes

'bytDataToHash' denotes a 'variable' where a 'method' was expected

What error is this? how to correct the code

You can correct it by posting your question to a C# newsgroup.

Probably the compiler is expecting bytDataToHash()
