// @SuppressWarnings ("unchecked")     Public Invoice (Control ctrl) {

    dia = Integer.toString(c2.get(Calendar.DATE));
    mes = Integer.toString(c2.get(Calendar.MONTH)+1);

    initComponents();
    Dimension tamFrame=this.getSize();
    Dimension tamPantalla=Toolkit.getDefaultToolkit().getScreenSize(); 
    setLocation((tamPantalla.width-tamFrame.width)/2, (tamPantalla.height-tamFrame.height)/12);
