No problem: using System; using System.Collections.Generic; using System.ComponentModel; using System.Data; using System.Drawing; using System.Linq; using System.Text; using System.Windows.Forms; namespace WindowsFormsApplication1 { public partial class Form1 : Form { public Form1() { InitializeComponent(); } private void btnSubtract_Click(object sender, EventArgs e) { int x, y, diff; if(!int.TryParse(textBox1.Text, out x)) { MessageBox.Show("Not a valid integer. Please re-enter."); textBox1.Focus(); return; } if(!int.TryParse(textBox2.Text, out y)) { MessageBox.Show("Not a valid integer. Please re-enter."); textBox2.Focus(); return; } diff = x + ~y + 1; textBox3.Text = diff.ToString(); } } }

Try this: using System; class Program { static void Main() { int x, y, diff; Console.WriteLine("Enter 0 at any time to quit. Invalid integers will be treated as 0.
"); while (true) { Console.Write("Input first integer : "); int.TryParse(Console.ReadLine(), out x); if (x == 0) return; Console.Write("Input integer to be subtracted : "); int.TryParse(Console.ReadLine(), out y); if (y == 0) return; diff = x + ~y + 1; Console.WriteLine("{0} minus {1} = {2}
", x, y, diff); } } }
