如何刷新Windows资源管理器 [英] How to refresh Windows Explorer

问题描述

>

可以更改卷的名称。

我将名称更改为脊髓磁盘

A network volume's name can be changed.
I changed the name to Spinal Disk

要更改网络名称，请执行

To change a network name, I do

• 在注册表中写入新名称。


• 使用像DefineDosDeviceW这样的功能附加我的网络卷。在这个时间，Windows资源管理器读取我的猜测注册表。


• SHChangeNotify（SHCNE_DRIVEADD，SHCNF_PATH，root，NULL）; //确定。


• SendMessageTimeout（HWND_BROADCAST，WM_DEVICECHANGE，message，（LPARAM）（& dbv）， - SMTO_ABORTIFHUNG，200，&dwResult）; //

• Write new name in Registry.
• Attach my network volume using functions like DefineDosDeviceW. In this timing, Windows explorer read registry in my guessing.
• SHChangeNotify(SHCNE_DRIVEADD, SHCNF_PATH, root, NULL); // To be sure.
• SendMessageTimeout(HWND_BROADCAST, WM_DEVICECHANGE, message, (LPARAM)(&dbv), - SMTO_ABORTIFHUNG, 200, &dwResult); // To be sure again!

它可以工作，但有时候不工作，即使我使用SHChangeNotify和WM_DEVICECHANGE确定。有时，新名称不会应用于Windows资源管理器中。

但是如果我终止Explorer并重新执行，则应用的名称。

It works, but sometimes doesn't work even though I use SHChangeNotify and WM_DEVICECHANGE to be sure. Sometimes, the new name is not applied in Windows Explorer.
But if I terminate Explorer and re-execute, the name applied.

我找到一个有Windows资源管理器刷新的界面（是正确的语法吗？对不起，我不能很好地表达这句话。）

是否有适当的功能？资源管理器应重新读取注册表并刷新。

I'm finding an interface having Windows Explorer refreshed.(Is it correct syntax? Sorry, I can't express this sentence well.)
Is there a proper function? Explorer should re-read registry and be refreshed.

推荐答案

不幸的是，Explorer每次都不能刷新。因为太多的应用程序表现不佳，并且总是使用SHCNE_ALLEVENTS的SHChangeNotify（）。想象一下，如果资源管理器每次收到该通知时总是刷新一遍（是的，有时每秒多次！）。

Unfortunately, Explorer simply can't refresh every time it is told so. Because way too many apps behave badly, and just always use SHChangeNotify() with SHCNE_ALLEVENTS. Imagine if the explorer would really always refresh everything every time it receives that notification (yes, sometimes several times per second!).

这就是为什么它有时不工作。

That's why it sometimes doesn't work.

但是这里是如何欺骗资源管理器：
从下往上发送多个路径的通知。通常足以首先发送例如 N：\folder ，然后 N：\ 才能真正刷新 \\ 。

But here's how you can 'trick' the explorer: Send a notification for more than one path, from the bottom up. Usually it's enough to first send a notification for e.g. N:\folder and then for N:\ to really refresh N:\.

您应该先发送WM_DEVICECHANGE消息，然后调用SHChangeNotify（）。

And you should send the WM_DEVICECHANGE message first, then call SHChangeNotify().
