passing variables

Question

okay, I've got a program where I get the coordinates of where the mouse clicked in the code for the form:

protected override void OnMouseDown(MouseEventArgs e)
{
           int x, y;
           x = e.X;
           y = e.Y;
           base.OnMouseDown (e);
}

and I want to pass the values of x and y to a separate class and method. How do I do that?

Someone has to tell me how to format my posts on this forum, because it's not recognizing the return key at all...

I'm not sure of exactly what you are asking (as you were not very specific), but if I understand you correctly, the best solution is probably this: Make x and y private variables of the main form. private int x; private int y; Next, make public variables X and Y of the form to return the value of the private variables. public int X { get { return x; } } public int Y { get { return y; } } Next, inside your class, make the function take as a parameter your main form. public void showCoord(Form1 mainForm) { MessageBox.Show("X is " + mainForm.X + ", and Y is " + mainForm.Y + ".", "Info", MessageBoxButtons.OK, MessageBoxIcon.Asterisk); } Next, when you call the function from your main form, pass the main form as the parameter. private void button2_Click(object sender, System.EventArgs e) { Class1 c1 = new Class1(); c1.showCoord(this); } Anyway, good luck with your project. PS to all C# pros, I have a graphics question in the GDI forum that I'd like answered. :)
