        ' Load EML file and display email headers.
        Dim email As New Chilkat.Email
        email.UnlockComponent("anything for 30-day trial")

        email.LoadEml("test.eml")

        Dim i As Integer
        Dim n As Integer

        ' Email header fields can be retrieved by name:
        ListBox1.Items.Add("Subject: " + email.GetHeaderField("subject"))

        ' Some email header fields are associated with properties for convenience:
        ListBox1.Items.Add("Subject: " + email.Subject)

        ' If more than one header field having the same name exists, your
        ' program may access them by iterating over the headers in the email
        ' by index:
        n = email.NumHeaderFields
        For i = 0 To n - 1
            ListBox1.Items.Add(email.GetHeaderFieldName(i) + ": " + _
                email.GetHeaderFieldValue(i))
