推荐答案

如果您想禁用/启用菜单，请阅读 ^ ]文章.在那里，您会找到答案.

如何实现呢?内部Menu_OnClick方法:
1)禁用菜单
2)显示第二个表格
内部Form_Closing(Form2)事件
1)启用菜单

If you would like to disable/enable menu, read this[^] article on msdn site. There you''ll find an answer.

How to achieve this? Inside Menu_OnClick method:
1) Disable your menu
2) Show second form
Inside Form_Closing (Form2) event
1) Enable your menu

是的，很简单，
请按照以下步骤操作:
>首先，您需要在程序类中创建主窗体或mdi窗体的静态对象.

>从启动屏幕启动程序时，显示此静态主窗体以初始化其对象.

>现在以这种mdi形式创建菜单，以显示使其成为父形式的子形式.
现在是主要部分...
在子窗体的窗体关闭事件上，禁用MDI窗体的菜单.在这里您将不会创建任何对象，仅引用您在Program类中创建的静态对象.

Yes its simple,
follow these steps:
> You first need to create a static object of the main form or mdi form in your program class.

> When you start program from Splash screen, show this static main form intializing its object.

> now create menus in this mdi form to show child form making it parent.
Now here comes the main part...
on form closing event of child form disable the menu of the mdi form. Here you will not create any object, just refer to the static object you created in Program class.
