You can't use MessageBox in ASP.NET. You don't have any graphical user
interface, so there is nowhere that you can display the messagebox.
If you were allowed to use a messagebox in ASP.NET, it would pop up on
the web server where noone would see it, and IIS would hang indefinitely
waiting for someone to click it.
