To drag and drop objects from one instance of an application to another, the object must be serializable. Otherwise, the cast will not work as expected. To accomplish this, you can add the Serializable attribute to your Entity class, and optionally implement the ISerializable interface.

For an introduction on how to make a class Serializable, see: msdn.microsoft.com/en-us/library/4abbf6k...).aspx This is the same issue with using the Clipboard. A great example can be seen on this CodeProject site: codeproject.com/KBecause s/copycustomclasstoclipbrd.aspx.

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.
