ProgressBar disappears when changed from within a thread?

Woah there! Stay the heck away from CheckForIllegalCrossThreadClass. That property, while Microsoft made it available and I'm sure there is a very, very, very rare (and I mean rare ) use for it, don't ever touch it.

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.
