Using Secure License Manager, it is possible to embed custom data in license keys. To embed custom data in license keys, type the custom data text in the "Custom License Data" text input box and then click on the "Generate" button to generate license keys.
Figure 1. Custom License Data.
The following code sample shows how to access the embedded license data at runtime during license validation using the SecureLicense.CustomData.StringValue.
using System;
using System.ComponentModel;
using System.Windows.Forms;
using SimpleMode.SecureLicenseManager;
namespace Example2
{
public partial class TestForm : Form
{
private const string ValidationKey = "Type / Copy Your Validation Key Here";
public TestForm()
{
InitializeComponent();
}
private void buttonCheckCustomData_Click(object sender, EventArgs e)
{
SecureLicense secureLicense = new SecureLicense(ValidationKey);
secureLicense.Activate(this.textBoxLicenseKey.Text.Trim());
if (secureLicense.IsValid)
{
MessageBox.Show("Custom License Data : " + secureLicense.CustomData.StringValue);
}
else
{
MessageBox.Show("License key activation failed!");
}
}
}
}
Imports System;
Imports System.ComponentModel
Imports System.Windows.Forms

Namespace Example2
Public Partial Class TestForm
Inherits Form
Private Const ValidationKey As String = "Type / Copy Your Validation Key Here"
Public Sub New()

Private Sub buttonCheckCustomData_Click(sender As Object, e As EventArgs)
Dim secureLicense As New SecureLicense(ValidationKey)
secureLicense.Activate(Me.textBoxLicenseKey.Text.Trim())
If secureLicense.IsValid Then
MessageBox.Show("Custom License Data : " & secureLicense.CustomData.StringValue)
Else
MessageBox.Show("License key activation failed!")
End If
End Sub
End Class
End Namespace
