'Return the presence of an extended property represented
'by theGuid in the ExtendedProperties collection.
Private Function HasExtendedProperty( _
ByVal theExtendedProperties As IInkExtendedProperties, _
ByVal theGuid As String) As Boolean
    HasExtendedProperty = False
    Dim theExtendedProperty As IInkExtendedProperty
    For Each theExtendedProperty In theExtendedProperties
        If theExtendedProperty.Guid = theGuid Then
            HasExtendedProperty = True
        End If
    Next
End Function
