TabControl with the same controls on each tab?

I would do it like this (The code is for a WPF solution, have overlooed the WinForm-Tag. But should work similar.).

This is because primitive types will passed by value, complex by reference! I have found this example about reference and value types and hope you can learn from that 1. After you have read it try this.

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.
