When I try to run this calculator, I get an error at this line:     this.Load += new System.EventHandler(this.Form1_Load);

'Calculator2.Form1' does not contain a definition for 'Form1_Load' and no extension method 'Form1_Load' accepting a first argument of type 'Calculator2.Form1' could be found (are you missing a using directive or an assembly reference?)

            txtScore.KeyPress += new KeyPressEventHandler(textBox1_KeyPress);
            txtScore.Focus();
