Large Quantities

I understand the idea of how to make a bunch of rectangles in random places, but I just can't follow through. You would have
rect1 - 25. You would haveRandom r. How would I make them draw at random places on a form? Thanks in advance.- I love D-flat!

Hi, in the OnPaint method of the Control/Form you want to draw your shapes in, have a for loop that generates random x,y,width,height values (all within legal bounds), and call Graphics.DrawRectangle (or FillRectangle) for each of them. Alternatively, generate those numbers elsewhere and store them; then have your OnPaint feed them to Graphics.DrawRectangle. :)

How would I select a large amount of (say) rect1 - 25? I saw a post a while back that did something close, but I can't find it. It's like... (my example)
rect(and a for loop here) { }... or something like it -- modified at 11:28 Saturday 1st December, 2007- I love D-flat!

Something along these lines:
List< Rectangle> rects=new List< Rectangle>;
Random rand=new Random();
for (int i=0; i< RECT_COUNT; i++) {
int x=rand.Next(xBounds);
int y=rand.Next(yBounds);
int w=rand.Next(widBounds);
int h=rand.Next(heiBounds);
Rect r=new Rectangle(x,y,w,h);
rects.Add(r);
}
...
Graphics g=e.Graphics;
foreach(Rectangle r in rects) {
g.DrawRectangle(r);
}:)

Oh. Thanks.
