Hi Benoit, Perhaps it would be best to explain at a higher level what you are trying to achieve with your application or the task you have in mind. Then others might be able to advice how they would tackle it, rather than dive in at low level elements/issues that won't be an issue if you tackle the whole task in a more appropriate way.
