navigation - 操作 Windows 7 Explorer 导航 Pane

Question

根据我在 superuser 收到的答案，很明显，我必须将以下内容添加到自定义资源管理器窗口启动器中。我想启动一个 Root过的资源管理器 View ，对于 就是那个窗口使导航 Pane 看起来像旧的 Windows XP 文件夹 Pane 。我已经wrote a program将这些文件夹 View 的快捷方式放置在“开始”菜单上，因此更改快捷方式以通过启动器运行是微不足道的。

这是 XP 文件夹 Pane :



这是 Windows 7 导航 Pane :

Answer 1

好吧，我没有时间完全完成这段代码(它是在 C# 中，我不知道你想要什么，但你没有真正指定)。其基本前提是在 .NET 窗体中托管 ExplorerBrowser 控件(使用您需要获取并添加引用的 WindowsAPICodePack)，等待直到 TreeView 创建并子类化窗口以允许我们拦截项目插入。

不幸的是，没有什么是简单的，文本并没有让您直接了解项目是什么(因为他们没有设置它)，您需要做的是从 insertStruct.lParam 获取 PIDL。并将其解析为有意义的内容，可能使用 IShellFolder界面。然后，您可以有选择地删除项目(通过将 0 作为 m.Result 返回)，并且您可以拦截任何您需要的内容。你会认为会有一个简单的解决方案，但我想你的运气并不好 ;) 希望它会有所帮助。

另一种可能是做类似的(直接使用主机资源管理器)但使用类似 detours 的东西 Hook 注册表功能并有选择地更改资源管理器控件获得的 View ，允许某些注册表调整工作。
