问题描述
根据我在 superuser 上收到的答案,很明显,我会必须将以下内容添加到自定义资源管理器窗口启动器中.我要启动一个根目录化的资源管理器视图,并为 正好是该窗口 ,使导航窗格看起来像旧的Windows XP文件夹窗格.我已经编写了程序,将这些文件夹视图的快捷方式放在开始"上菜单,因此更改在启动器中运行的快捷方式很简单.
Based on the answers I received at superuser, it's clear that I'll have to add the following to a custom Explorer Window launcher. I want to launch a rooted explorer view, and for just that window make the navigation pane look like the old Windows XP folders pane. I already wrote a program to place shortcuts to these folder views on the Start Menu, so changing the shortcuts to run through a launcher is trivial.
推荐答案
好吧,我还没有时间完全完成这段代码(而且在C#中,我不知道您想要什么,但是您做了并没有具体说明).这样做的基本前提是将ExplorerBrowser控件托管在.NET表单中(使用 WindowsAPICodePack 您将需要获取并添加对它的引用),等到创建TreeView并将其子类化为窗口,以允许我们拦截项目插入.
Okay well I haven't got the time to completely finish this code (and it is in C# which I have no idea is what you want, but you didn't really specify). The basic premise of this is hosting the ExplorerBrowser control inside a .NET Form (using the WindowsAPICodePack which you will need to get and add a reference to), wait around till the TreeView has been created and subclassing the window to allow us to intercept the item insertations.
不幸的是,没有什么比这更简单了,文本并不能直接让您了解项目的含义(因为他们没有设置项目),您需要做的就是从insertStruct.lParam
获取PIDL并进行解析可能会使用IShellFolder
接口将其转换为有意义的内容.然后,您可以有选择地删除项目(通过返回0作为m.Result
),并且可以拦截需要的其他任何内容.您可能会认为有一个简单的解决方案,但我想您的运气还不够好;)希望能有所帮助.
Unfortunately nothing is ever simple, the text doesn't give you a direct idea of what the item is (cause they do not set it), what you would need to do is get the PIDL from the insertStruct.lParam
and parse it into something meaningful, probably using the IShellFolder
interface. You can then selectively remove items (by returning 0 as the m.Result
) and you can intercept anything else you need to. You would think there would be a simple solution but I guess your luck isn't in ;) Hope it helps slightly.
一种替代方法可能是类似的操作(直接托管浏览器),但使用类似 钩住注册表功能并有选择地更改资源管理器控件获得的视图,从而允许某些注册表调整工作.
An alternative might be do similar (host explorer directly) but use something like detours to hook the registry functions and selectively change the view the explorer control gets allowing some of the registry tweaking to work.
