At the end of this event handler, the NewForm is shown using the call to ShowModal, which results in the screen shown in figure 5.
在该事件处理程序的结尾，通过调用ShowModal显示了NewForm，其结果如图5所示。

As a little hint, I would suggest adding these buttons to the skeleton form in NewForm, so the changes that you make will be used in all newly generated forms.
