CLR Errors - crashing without actually running

are usually caused by invalid references

to a windows program you can add the following for error handling in program.cs

  [STAThread]

        static void Main()

        {

            AppDomain.CurrentDomain.UnhandledException +=

            new UnhandledExceptionEventHandler(CurrentDomain_UnhandledException);

);

            Application.EnableVisualStyles();

            Application.SetCompatibleTextRenderingDefault(false);

            //CheckForShortcut();

            Application.Run(new Invoice());

        }

        static void CurrentDomain_UnhandledException

  (object sender, UnhandledExceptionEventArgs e)

        {

            try

            {

                Exception ex = (Exception)e.ExceptionObject;

                MessageBox.Show(ex.Message + ex.StackTrace,

                      "Fatal Error", MessageBoxButtons.OK, MessageBoxIcon.Stop);

            }

            finally

            {

                Application.Exit();

            }

        }
