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); } } }
