I am wondering what I am missing in the attached code that is making it impossible for me to make the attached source code VB.NET program work.

For someone experienced in MVC (Model-View-Controller) I know that the attached thing is child's play but for me who is just starting on it I am really lost  right now despite my best efforts...

I am trying to implement the observer pattern and know that the code in my second attempt ("Second Try trying Implementing MVC using Observer Pattern still far from success"  is closer to success than the first one  ... nevertheless I'm not quite there yet and would benefit from any help that someone more experienced in MVC VB.NET implementation can give .. hence this letter.

So far Im really stumped and would forever be grateful for any help you could give.

Gratefully,
Matt
