GDI+ nonrectangular forms - what am i doing wrong?

[esdee]

i have this in the form constructor:

			GraphicsPath p = new GraphicsPath();

			Point[] points = {   new Point(0, 0), new Point(100, 0),
								 new Point(150, 50), new Point(250, 50),
								 new Point(250, 350), new Point(0, 350) };

			p.AddPolygon(points);
			this.Region = new Region(p);

which creates a poligonal form.
i want to have the upper part colored, and im using the same coordinates, like:

Graphics g = e.Graphics;
Point[] points = {   new Point(0, 0), new Point(100, 0),
								 new Point(150, 50), new Point(0, 50)};
Rectangle r = new Rectangle(points); 
g.FillRectangle(new SolidBrush(Color.Aqua), r);

but the colored part doesnt match the part of the window i want! do i have to make coordinates shift or something? i tried rectangletoscreen etc but nothing worked ...

somehow i have marked this one as a news topic...sorry

I think you need to subdivide it into two separate regions that adjoin each other along a common edge, rather than overlaying one on top of the other.

it is not two regions - it only one, and want a prt of it to be fill with some color. the problem is there is a mismatch of the coordinates: when using

new Point(0, 0), new Point(100, 0), 
new Point(150, 50), new Point(250, 50)

to define a part of the region, and then use the same part for the fill - they dont match ! i mean the filled part is not what i expect.

Try my idea and get back to me.
