推荐答案

您有两个单独的属性页类，可能是由同一对象创建的，即属性表的实例:您应该使用诸如中介之类的属性表对象将值从一页传递到另一页.
本文:"对话框通信"说明了如何交换数据；艰难的情况是完全不同的，技术是相当普遍的.

You have two separate property page classes, probably created by the same object, i.e. an instance of the property sheet: you should use such property sheet object as intermediary to pass values from one page to the other one.
This article: "Dialogs Communication" explains how to to exchange data; tough the scenario is quite different, the technique is quite general.
