.The Visual Basic 6.0 Upgrade Assessment Tool measures application upgrade effort. This tool analyzes the application components and the relationships between them from an upgrade perspective, considering elements, constructs, and features that consume resources during an upgrade. It generates a group of reports that are used for calculations related to task effort and cost. The user can specify configuration values that will override the initial estimation inputs to adapt the assessment tool to their needs.
.IntroductionIn this simple article, I am going to show how you can protect your software from unauthorized copying by creating a serial number/activation key pair based on the physical address (MAC) of the network adapter on the client's machine. Getting the MAC Address and Generating the Serial NumberThe first step is to get the MAC address of the client's machine. This could be achieved by using the ManagementClass class located in the System.Management assembly. We have to add a reference to that assembly to our project, and import it into SecurityManager.vb, which will be the class in which we place the GetSerial and CheckKey functions. These two functions will be responsible for generating the serial number from the MAC address and checking whether the key entered by the user is valid.
As a first step, we define the GetSerial function as follows: Public Function GetSerial As Long Dim mc As New ManagementClass('Win32NetworkAdapterConfiguration')Dim mac As String = ' Getting network adapters collection Dim moc As ManagementObjectCollection = mc.GetInstances' Here we iterate over available network adapters, ' picking the first possible one For Each mo As ManagementObject In mocIf mo.Item('IPEnabled') Thenmac = mo.Item('MacAddress').ToStringExit For End If Nextmc.Dispose' This is a simple function that we use to get a serial out ' of our MAC address. Say that x is the MAC and y is the serial, ' the function would be y += xi + (i. 2) where i is the index ' of MAC address element. JimSharples 18-Oct-Oct-12 21:52ManagementClass in the SecurityManager Class GetSerial Function does not appear to work under.Net 4.I substituted the following:Imports System.Net.NetworkInformationPublic Function GetSerial As Long Dim mac As String = ' ' Dim nics As NetworkInterface = NetworkInterface.GetAllNetworkInterfacesIf nics Is Nothing OrElse nics.Length 0 Then Exit For Next End If ' In case we get no valid adapter (unlikely), then If Len(mac) = 0 Then mac = ' 6CF0490FC2F6'. Continue with GetSerial function.
This is the whole alternative function.The way I use it is to check for a file (called 'Z1' or anything you choose) in the application folder when my application starts. If it does not exist, the program has been run for the first time, and I notify the user that they have 10 (or whatever) times left to run the program. I store the number 9 in the Z1 file.Next time the program is run, I check for Z1 again, see it has number 9 stored, inform the user they have 9 more times left, and store 8 in the file etc etc.The program has a menu item 'Register'. If they do supply the correct serial/key pair, then I store 'Registered to xxxxx' in the Z1 file.
