Introduction to Usage:

1 "Call multithread. Dowork ();

2 "This popup box before calling MessageBox.Show (" message "," title "));

3 "Because the popup box blocks the main thread. So the other thread calls to be started before the main thread, so that he has been inquiring the main thread. To get a handle.
