How can I get my "Form2" CANCEL button to close the form without making user's click the upper right "X" ?
--------------------------------------------
Example
 1. create Form1 & Form2
 2. add below code to Form1 "Open Form2" button
        private void button2_Click(object sender, EventArgs e)
        {
            Form2 frm = new Form2();
            frm.Show();
        }
 3. add below code to Form2 "Cancel" button
        private void button2_Click(object sender, EventArgs e)
        {
            Form2..... (cancel or close) ?
        }

Might have misunderstood the question, but the following for Form2's Cancel button event handler should do it:

private void button2_Click(object sender, EventArgs e)
{
  this.Close();
}

Or do you want to close Form2 from a button click on Form1?

As an aside, if you want to force the user to accept or cancel whatever's on Form2 before they return to Form1, try changing the

        private void button2_Click(object sender, EventArgs e)
        {
            Form2 frm = new Form2();
            frm.Show();
        }

method in Form1 to be

        private void button2_Click(object sender, EventArgs e)
        {
            Form2 frm = new Form2();
            frm.ShowDialog(); // Note ShowDialog instead of Show
        }

ShowDialog'll wait until the Form created is closed.
