vb.net – 复制Windows取消隐藏文件夹和文件功能

我知道我可以通过编辑注册表项并重新启动explorer.exe来完成此 *** 作,但这会关闭所有打开的资源管理器windows,我不希望这样.

有没有人知道windows是如何通过简单点击一个复选框以及我如何能够在VB.net中编码它来做到这一点的？

对此的任何意见都提前非常感谢.

编辑：那么它看起来像我发现作品刷新windows资源管理器/文件浏览器,可应用于以下Drarig的答案,但我无法将其转换为VB.net作为原始的例子是在C#中的刷新方法.

'Original at https://stackoverflow.com/questions/2488727/refresh-windows-explorer-in-win7Private Sub refreshExplorer(ByVal explorerType As String)    Dim CLSID_ShellApplication As GuID = GuID.Parse("13709620-C279-11CE-A49E-444553540000")    Dim shellApplicationType As Type = Type.GetTypeFromCLSID(CLSID_ShellApplication,True)    Dim shellApplication As Object = Activator.CreateInstance(shellApplicationType)    Dim windows As Object = shellApplicationType.InvokeMember("windows",Reflection.BindingFlags.InvokeMethod,nothing,shellApplication,New Object() {})    Dim windowsType As Type = windows.GetType()    Dim count As Object = windowsType.InvokeMember("Count",Reflection.BindingFlags.GetProperty,windows,nothing)    For i As Integer = 0 To CType(count,Integer)        Dim item As Object = windowsType.InvokeMember("Item",New Object() {i})        Dim itemType As Type = item.GetType()        'Only fresh windows explorer windows        Dim itemname As String = CType(itemType.InvokeMember("name",item,nothing),String)        If itemname = explorerType Then            itemType.InvokeMember("Refresh",nothing)        End If    NextEnd Sub

当我将itemType设置为上面的Type = item.GetType()时,我得到一个异常对象引用未设置为对象的实例.我无法弄清楚哪个对象没有被创建.当我单步执行代码时,它看起来像windowsType包含一个对象.有没有人对此有任何想法？一旦解决了这个问题,我就可以将它应用到下面的Drarig解决方案中.

解决方法 好吧,我希望我能早点得到你,但最近忙于工作.今天我花了一点时间来弄清楚这一点,因为我喜欢挖掘我之前没有做过的事情.这是一个新项目的全班;没有时间把它包装在一个单独的课堂上.我相信这会得到你所需要的.它比我想象的更难获得正确的句柄然后发送命令,但我得到了它.希望对你有帮助.

附：你可以省略一些东西,特别是用于加载的布尔值,这样我就可以在加载时拉回当前值并检查/取消选中CheckBox.

注意：这是在windows 7,8和10上试用和测试的
