Windows API代码包v1.1

CommonOpenFileDialog类的实现似乎存在明显的不一致。文档说有一个SelectionChanged事件，可以附加一个处理程序。我已经完成了这件事并且事件发生了。到目前为止一直这么好！



但是，似乎没有任何方法可以确定用户在打开或取消之前选择了哪个文件按下按钮。我想使用所选项目在一个额外的控件或两个我已添加到对话框的控件成员中的控件中显示一些信息。控件显示，但无法使用所选文件信息更新这些控件。



那么...... SelectionChanged事件的故事是什么？

There appears to be a glaring inconsistency in the implementation of the CommonOpenFileDialog class. Documentation says that there is a SelectionChanged event to which a handler can be attached. This I have done and the event itself fires. So far so good!

However, there doesn't appear to be any way in which I can determine which file has been selected by the user before the Open or Cancel buttons are pressed. I want to use the selected item to display some information in an extra control or two that I have added to the Controls member of the dialog. The controls display, but there is no way of using the selected file information to update these controls.

So... what's the story with the SelectionChanged event?
