Refresh Windows Explorer in Win7
提问by Paya
My program sets "HKCU\Software\Microsoft\Windows\CurrentVersion\Explorer\Advanced"value "Hidden". Hovewer I'm not able to refresh the explorer to take into account this change. I've tried:
我的程序设置"HKCU\Software\Microsoft\Windows\CurrentVersion\Explorer\Advanced"value "Hidden"。但是，我无法刷新资源管理器以考虑此更改。我试过了：
1)
1)
SHChangeNotify(SHCNE_ASSOCCHANGED, SHCNF_IDLIST, IntPtr.Zero, IntPtr.Zero);`
2)
2)
SHELLSTATE state = new SHELLSTATE();
state.fShowAllObjects = (uint)1;
SHGetSetSettings(ref state, SSF.SSF_SHOWALLOBJECTS, true);
3)
3)
SendMessageTimeout(HWND_BROADCAST, WM_SETTINGCHANGE, SPI_SETNONCLIENTMETRICS, 0, SMTO_ABORTIFHUNG, 5000, ref dwResult);
4)
4)
SendMessage(HWND_BROADCAST, WM_COMMAND, 28931 /* Refresh */, 0);
Nothing works. So what should I do? If I refresh Explorer myself with F5, then it works. Hovewer I would like some elegant solution, so it would refresh the display everywhere, even in OpenFile/SaveFiledialogs, which are currently open.
没有任何作用。所以我该怎么做？如果我自己用 F5 刷新资源管理器，那么它就可以工作。然而，我想要一些优雅的解决方案，因此它会在任何地方刷新显示，即使在当前打开的OpenFile/SaveFile对话框中也是如此。
I'm using C# .NET, Win7.

As Anderspointed out, there is a simple way to refresh explorer windows using COM:
正如所Anders指出的，有一种使用 COM 刷新资源管理器窗口的简单方法：
Guid CLSID_ShellApplication = new Guid("13709620-C279-11CE-A49E-444553540000");
Type shellApplicationType = Type.GetTypeFromCLSID(CLSID_ShellApplication, true);
dynamic shellApplication = Activator.CreateInstance(shellApplicationType);
dynamic windows = shellApplication.Windows();
for (int i = 0; i < windows.Count; i++)
windows.Item(i).Refresh();
So this part is done.Hovewer I still need to refresh the OpenFile/SaveFiledialogs, and the code above doesn't do that. Does anybody know how to refresh those dialogs?
这样这部分就完成了。但是我仍然需要刷新OpenFile/SaveFile对话框，而上面的代码并没有这样做。有人知道如何刷新这些对话框吗？
An important point is that if I change the "Show Hidden Files" in Folder Options in Control panel, those OpenFile/SaveFiledialogs are not refreshed by the system, I must refresh them manually using F5. I'm just looking for a method how to refresh all those dialogs using C#, so I don't need to press F5 anymore...
重要的一点是，如果我更改控制面板中文件夹选项中的“显示隐藏文件”，系统不会刷新这些OpenFile/SaveFile对话框，我必须使用 F5 手动刷新它们。我只是在寻找一种如何使用 C# 刷新所有这些对话框的方法，所以我不再需要按 F5...

Ok, so new problem with the code above - it refresh not only windows explorers, but also internet explorers... Any idea how to refresh windows explorers ONLY?
好的，上面代码的新问题 - 它不仅刷新 Windows 资源管理器，还刷新 Internet Explorer ......知道如何仅刷新 Windows 资源管理器吗？

I figured out a way to check if the windows was a Windows Explorer window, and don't have enough of a rep to add a comment so thought I'd submit it as an answer to help you out because this question helped me out.
我想出了一种方法来检查 Windows 是否是 Windows 资源管理器窗口，并且没有足够的代表来添加评论，所以我想我会提交它作为帮助你的答案，因为这个问题帮助了我。

Guid CLSID_ShellApplication = new Guid("13709620-C279-11CE-A49E-444553540000");
Type shellApplicationType = Type.GetTypeFromCLSID(CLSID_ShellApplication, true);
object shellApplication = Activator.CreateInstance(shellApplicationType);
object windows = shellApplicationType.InvokeMember("Windows", System.Reflection.BindingFlags.InvokeMethod, null, shellApplication, new object[] { });
Type windowsType = windows.GetType();
object count = windowsType.InvokeMember("Count", System.Reflection.BindingFlags.GetProperty, null, windows, null);
for (int i = 0; i < (int)count; i++)
{
object item = windowsType.InvokeMember("Item", System.Reflection.BindingFlags.InvokeMethod, null, windows, new object[] { i });
Type itemType = item.GetType();
// only refresh windows explorers
string itemName = (string)itemType.InvokeMember("Name", System.Reflection.BindingFlags.GetProperty, null, item, null);
if (itemName == "Windows Explorer")
{
itemType.InvokeMember("Refresh", System.Reflection.BindingFlags.InvokeMethod, null, item, null);
}

I don't know about Open/Save dialogs, but you can get a list of open explorer windows with COM automation, the Shell.Applicationobject has a collection of windows, or CoCreate IID_IShellWindows directly, each window in the list has a refresh method.
我不知道打开/保存对话框，但是你可以通过 COM 自动化获得一个打开的资源管理器窗口列表，Shell.Application对象有一个windows 集合，或者直接 CoCreate IID_IShellWindows，列表中的每个窗口都有一个刷新方法.
WSH/JScript:
WSH/JScript：
for(var sw=new ActiveXObject("Shell.Application").Windows(),i=0;i<sw.Count; ++i)
sw.Item(i).Refresh();
I don't know about C#, but here are examples dealing with shell windows in WSH/JScriptand c++
我不了解 C#，但这里有一些在WSH/JScript和C++ 中处理 shell 窗口的示例

When you install an application that registers a file type, Explorer windows often refresh to indicate the new association - could you spy on the API calls that an installer is making to see how it refreshes the window?
当您安装注册文件类型的应用程序时，资源管理器窗口经常刷新以指示新的关联 - 您能否监视安装程序进行的 API 调用以查看它如何刷新窗口？

With Windows 10 having changed the name of the Explorer window:
Windows 10 更改了资源管理器窗口的名称：
if ((itemName == "Windows Explorer") || (itemName == "File Explorer")) {
itemType.InvokeMember("Refresh", System.Reflection.BindingFlags.InvokeMethod, null, item, null);
}
