You should do something like this where totalProgress will be shown in progressBar, doWork is executed not in UI thread, that is the purpose of BackgroundWorker.
The issue is that bg1 will always report that it is busy while it runs its DoWork method.
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.
