You need to handle Form1's FormClosing event (add the skeleton handler from the Properties Box):

private void Form1_FormClosing(object sender, FormClosingEventArgs e)
{
    DialogResult dr = MessageBox.Show("Are you sure you want to quit the application?", "Confirmation required", MessageBoxButtons.YesNo);
    if (dr == DialogResult.No) e.Cancel = true;
}

If the user clicks the 'No' button, the closure of the form (and hence the application) will be cancelled.
