Update

I haven't had time to work on the code for two months now. I added a lot of code to implement the Tree control. After I finished the implementation it didn't work. The code crashes and I don't have much clue on what it's wrong. Bare in mind that I'm pretty ignorant on the Container control, a complex beast.

Finally soon I'll be able to recover my old computer where I could do some more coding, but for now I don't have time.

Regards.
