		Point[] hatcharea = new Point[6]
				{	new Point(RightBtm.X,0), new Point(this.ClientRectangle.Right,0),
					new Point(this.ClientRectangle.Right,this.ClientRectangle.Bottom),
					new Point(this.ClientRectangle.Left,this.ClientRectangle.Bottom),
					new Point(this.ClientRectangle.Left,RightBtm.Y),
					new Point(RightBtm.X,RightBtm.Y),
				};

At the end of the last line, there's a surplus comma. shouldn't the compiler complain here? it doesn't. (VS .NET 2003)

While the extra comma isnt needed the compiler will simply ignore it if it exists. It's by design that this isnt an error.

Nope. Don't think it is, in C, neither. (In fact, other languages may also have the same result.)

I believe the reason for this may be the same as why you can do this:

enum SomeEnum
{
Option1,
Option2,
Option3,
};

I heard that the reason for this is that it's easier to generate automatically (as in computer-generated).

yeah, that makes sense, that also came to my mind.
