events again

[frazer]

with regards to events why do i need to derive a class from EventArgs? Some

why is it needed and what is its use

It's really about consistency. It's not an enforced rule like the
requirement that all exceptions must inherit from System.Exception, but it
makes sense as a sort of unwritten standard.

You don't *have* to inherit from System.EventArgs though. Your
delegate/prototypes can be coded any other way you want.
