The lines above start Form1 as the main form. There's just 1 thread
(STAThread), as most gui's just use 1 thread, so application.run ,
starts the form and passes the execution to that form, which then is
the executing code on the single thread of the application. If you also
want to show form2, open it from form1.

Re: Form.ShowDialog is abnormal after Application.Run

But why the following code is right ?
new Form2().ShowDia log();
Application.Run (new Form1());
