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 have Random r. How would I make them draw at random places on a form? Thanks in advance.

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)<br />
{<br />
<br />
}

... or something like it

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);
}

I have declared an array like this

"ArrayList tableNames = new ArrayList();"

and I have added some values to it using
"tableNames.Add(row["TABLE_NAME"].ToString());"

Now I want to traverse it untill the last element.

You must be joking.

Your question tells me that you're very new to C#. You should buy a beginner book and work through it. You should certainly be aware of basic language constructs like for each before you start trying to work with databases, etc.

First, learn about foreach.

Second, learn about System.Collections.Generic.List<string>.

Third, learn that the .ToString() on your row["TABLE_NAME"] is likely unnecessary, try a cast instead.

Fourth, if you're already traversing a DataTable why are you even asking?

Open and close the SAME form with one button, or two different forms?

event question

hi I have an event defined in a base class. I'd like to raise this directly from a derived class, but the compiler won't let me do this, so instead I created a method RaiseMyEvent(...) to raise the event in the base class. Can I raise the event a simpler way? (otherwise I'd need to create a RaiseEventX function for each event..)

thanks!

If you define a reference to another assembly in a project, you can call code in that assembly from the project.

BTW, this is a pretty basic question. You should really read a beginner's book on C#.
