Reading a Unique System ID

[rasutton]

I have a requirement to read/get a a unique ID from a computer that some software I wrote will run on. I figured either getting the Windows OEM#, CD Key, or the Processor/chip number are good methods but I'm not sure where to start on this one.

Any help/code example would be great! I'm fairly new to VB client programming. Thanks in advance for you help.

You can read the hard drive serial number

Private Declare Function GetVolumeInformation Lib _
"kernel32.dll" Alias "GetVolumeInformationA" (ByVal _
lpRootPathName As String, ByVal lpVolumeNameBuffer As _
String, ByVal nVolumeNameSize As Integer, _
lpVolumeSerialNumber As Long, lpMaximumComponentLength _
As Long, lpFileSystemFlags As Long, ByVal _
lpFileSystemNameBuffer As String, ByVal _
nFileSystemNameSize As Long) As Long



Function GetSerialNumber(strDrive As String) As Long
Dim SerialNum As Long
Dim Res As Long
Dim strTmp As String
Dim strTmp2 As String
strTmp = String$(255, Chr$(0))
strTmp2 = String$(255, Chr$(0))
Res = GetVolumeInformation(strDrive, strTmp, _
Len(strTmp), SerialNum, 0, 0, strTmp2, Len(strTmp2))
GetSerialNumber = SerialNum
End Function





Private Sub Command1_Click()
Me.Caption = GetSerialNumber("C:\")
End Sub
