|
|
If some customer does not have an Internet connection, you may wish to perform an activation on behalf of a customer. The procedure to do this is as follows:
1. In the CryptoLicensing UI, paste the customer's license code (generated with the "Limit Machines To" setting) in the bottom text box.
2. From the "Machine Code Provider" tab, select the "Explicitly Specified Machine Code" provider, and paste the machine code for the customer's machine which needs to be activated. Note: Use the CryptoLicense.GetLocalMachineCodeAsString method from your software and display the value returned by this method to the customer for him to Copy-Paste and send to you.
3. Click the "Validate License/Serial" button. The UI will communicate with the license service to activate the license code using the customer's machine code. After activation, the bottom text box will display the machine-locked license code returned by the license service. Send this license code back to the customer.
The same procedure can be done via the Generator API using following code:
[C#]
| Code: |
string ActivateLicenseOnCustomerBehalf(string customer_license_code, string customer_machine_code)
{
CustomCryptoLicense lic = new CustomCryptoLicense(customer_machine_code);
lic.LicenseCode = customer_license_code;
lic.ValidationKey = "..."; // Set to actual
lic.LicenseServiceURL = "..."; // Set to actual
// Handle the OnGetLocalMachineCode event to provide the customer's machine code during activation.
lic.OnGetLocalMachineCode += (o, e) => { e.MachineCode = Convert.FromBase64String(customer_machine_code); e.Handled = true; };
LicenseStatus status = lic.Status; // Validate (activate) the license code
return lic.LicenseCode; // This now contains the machine-locked license code returned by the license service
}
|
[VB.NET]
| Code: |
Private Function ActivateLicenseOnCustomerBehalf(customer_license_code As String, customer_machine_code As String) As String
Dim lic As New CustomCryptoLicense(customer_machine_code)
lic.LicenseCode = customer_license_code
lic.ValidationKey = "..." ' Set to actual
lic.LicenseServiceURL = "..." ' Set to actual
' Handle the OnGetLocalMachineCode event to provide the customer's machine code during activation.
AddHandler lic.OnGetLocalMachineCode,
Sub(o As Object, args As GetLocalMachineCodeEventArgs)
args.MachineCode = Convert.FromBase64String(customer_machine_code)
args.Handled = True
End Sub
Dim status As LicenseStatus = lic.Status ' Validate (activate) the license code
Return lic.LicenseCode ' This now contains the machine-locked license code returned by the license service
End Function
