The first question is somewhat open in nautre, and rather dependent on the controls you are using, and the design pattern (if any) that you are trying to adhere to. From a development perspective, if you are Unit Testing you should always consider seperation of concerns, and how tightly you want to bind your controls to your 'domain'. Is this an ASP.NET application?
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
