List of Errors in C# program.

I have a list of problems that I can't seem to solve for a final project in my introduction to programming course, and I was hoping that some of you may be assist me.

My First problem, is that I can't seem to populate my dynamically created labels with the xml elements that I want....
I want the labels to display the id of the nodes named "name1", but it only brings up the first name1 node, and loads it for each of the labels created!

Here is the entire XML so far:

Code:

---

<subject id="you">
    <name id="Me">
        <ring id="bob" count="12">
            <name1 id="Ghandi"></name1>
            <name1 id="Bob"></name1>
            <name1 id="Jerry"></name1>
            <name1 id="Tony"></name1>
            <name1 id="Francis"></name1>
            <name1 id="Fabio"></name1>
            <name1 id="Lulu"></name1>
            <name1 id="Genie"></name1>
            <name1 id="Sabrina"></name1>
            <name1 id="Bambi"></name1>
            <name1 id="Rambo"></name1>
            <name1 id="Larry"></name1>
        </ring>
    </name>
</subject>

If you run the program, you will see that when you click on myLabel, it will create the proper amount of defined elements/labels and position them in a circular pattern around the initial label, however, each label comes up with the text "Ghandi". Instead of loading Ghandi for one, Bob for another, and Jerry for the next created label, it loads Ghandi for all of them.


My Second problem is that I want myLabel to be populated with a random "ring" node. In my XML, I will create a list of "ring" nodes and I want the contents of myLabel to be populated by the id of a random ring node...but I have NO idea on how to accomplish that.

My FINAL problem with this code, is that I am trying to make it so that when you click on the dynamically created labels "lbl", it will reposition the label to the center. I tried to do this with the:

Code:

---

        private void lbl_Click(object sender, EventArgs e)
        {
                double x = Form1.ActiveForm.Width/2;
                double y = Form1.ACtiveForm.Height/2;
                this.Drawing.Point(x, y);       
        }

---

however, it is returning the variables x and y as null values.
So I tried:

Code:

---

        private void lbl_Click(object sender, EventArgs e)
        {
                this.Drawing.Point(50, 50);       
        }

---

But it is still returning the values as null!

How can I make the dynamically created label be centered when it is click on?

Thank you for any assistance you may provide!

1) -

2) Check out the System.Random class

3) To change a label location you use MyLabel.Location = new System.Drawing.Point(NewX, NewY);
