 try

            ...{
                // Turn off screen updating.
                Application.ScreenUpdating = false;

                Excel.Range rng = Application.get_Range("A1",missing);
                for (int i = 0; i <= 20; i++)
                ...{
                   
                    rng.get_Offset(i, 0).Value2 = i;
                    // Without the leading "''", these references
                    // get evaluated, rather than displayed directly.
                    rng.get_Offset(i, 1).Value2 = i*10;
                    rng.get_Offset(i, 2).Value2 = i*100;
                    rng.get_Offset(i, 3).Value2 = i*1000;
                }
                rng.CurrentRegion.Columns.AutoFit();

            }
            catch (Exception ex)

   ...{
                MessageBox.Show(ex.Message, Application.Name);
            }
            finally
            ...{
                // Turn on screen updating.
               Application.ScreenUpdating = true;
            }
