Control Refresh

You could, but that can lead to problems with re-entrancy and there are few situations using .NET where DoEvents is a necessary approach. You can do your processing in a BackgroundWorker and notify the UI in its DoWork event.

    public partial class Form1 : Form
    {
        public Form1( )
        {
            InitializeComponent( );            
        }

        private void button1_Click( object sender, EventArgs e )
        {
            BackgroundWorker worker = new BackgroundWorker( );
            worker.DoWork += worker_DoWork;
            worker.RunWorkerAsync( );
        }

        void worker_DoWork( object sender, DoWorkEventArgs e )
        {
            for ( int i = 0 ; i < 1000000000 ; ++i )
            {
                this.Invoke( new FooDelegate( Foo ), new object[ ] { i.ToString( ) } );
            }
        }

        private delegate void FooDelegate( string text );
        private void Foo( string text )
        {
            label1.Text = text;
        }
    }
