VB.net initiating the trial period in security software

In the following demo application

http://www.emoreau.com/Entries/Articles/2007/12/Licensing-a-VBNet-application.aspx

I imported Form1 into my project as well as the two class modules.

I run the code behind  "Test Status" as my main form starts

and have noticed that it says that I have 30 days left for the past three

days. What do I do to get the Trial days ticking down?

are you sure that CreateRegKeys has been called successfully at least once?

I don't think it has. As you can see I have moved the code around and call the procedure
oTest_Status as my main form loads. When this code runs the
variable strOldDay  contains the value "1EB9F900E0B160247FF8C9B899DE541B"
So CreateRegKeys(txtPassPhrase.Text) never runs. Should I perhaps just
run the CreateRegKeys(txtPassPhrase.Text) the very first time my app is run?
I had run your Demo project. Maybe that ran CreateRegKeys(txtPassPhrase.Text)


    Private Sub btnApplicationStatus_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnApplicationStatus.Click
        Call oTest_Status()
    End Sub

    Public Sub oTest_Status()
        Try
            Dim oReg As Microsoft.Win32.RegistryKey
            oReg = Microsoft.Win32.Registry.CurrentUser.OpenSubKey("Software", True)
            oReg = oReg.CreateSubKey(kstrRegSubKeyName)
            oReg = Microsoft.Win32.Registry.CurrentUser.OpenSubKey("Software\\" & kstrRegSubKeyName)
            Dim strOldDay As String = oReg.GetValue("UserSettings", "").ToString
            Dim strOldMonth As String = oReg.GetValue("operatingsystem", "").ToString
            Dim strOldYear As String = oReg.GetValue("GUID", "").ToString
            Dim strRegName As String = oReg.GetValue("USERID", "").ToString
            Dim strRegCode As String = oReg.GetValue("LOCALPATH", "").ToString
            Dim strCompID As String = oReg.GetValue("CompID", "").ToString
            Dim strTrialDone As String = oReg.GetValue("Enable", "").ToString
            oReg.Close()

            'If the keys should automatically be created, then create them.
            If strOldDay = "" Then
                CreateRegKeys(txtPassPhrase.Text)
            End If

You have to run it so something is written into the registry because this key is used to know when the trial period started.
