当你使用UpdateDate()函数的时候，你要清楚一个重要的点，那就是它的范围是你调用它的类所代表的框架中生效。举个例子：我们有一个主对话框，然后在其中建立了三个标签页。三个标签页分别关联了三个类。那么我们要在主对话框中使用标签页中关联了一个编辑框的变量时，如果你使用UpdateData(false)的时候，你会发现没有效果。你必须用标签页的类如CPage0 page0； page0.UpdateData(false);才会达到你的目的。

一、总结UpdateData()函数UpdateData(true);//用于将屏幕上控件中的数据交换到变量中。UpdateData(false);//用于将数据在屏幕中对应控件中显示出来。       当你使用了ClassWizard建立了控件和变量之间的联系后：当你修改了变量的值，而希望对话框控件更新显示，就应该在修改变量后调用UpdateData(FALSE)；如果你希望知道用户

首先，你需要按照 `updateDate` 进行自然排序，如果遇到更新日期相同的Map，接着再根据 `isCommon` 字段来进行进一步排序。这通常需要自定义一个比较器（Comparator），因为 Java 的 List 默认按元素自然顺序排序，...

关于UpdateData函数
0011411的专栏

关于UpdateData函数却有必要在这里讲解一下。在这里UpdateData函数起到控制Edit Box 显示内容的作用。当调用UpdataData (TRUE)的时候，程序会对控件对应的变量值进行刷新，也就是说会把控件中的输入值赋给对应的变量。而调用UpdataData (FALSE)的时候，程序则会把相应变量的值显示在对应的控件上面。
