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:
1)
SHChangeNotify(SHCNE_ASSOCCHANGED, SHCNF_IDLIST, IntPtr.Zero, IntPtr.Zero);`
SHELLSTATE state = new SHELLSTATE();
state.fShowAllObjects = (uint)1;
SHGetSetSettings(ref state, SSF.SSF_SHOWALLOBJECTS, true);
-
SendMessageTimeout(HWND_BROADCAST, WM_SETTINGCHANGE, SPI_SETNONCLIENTMETRICS, 0, SMTO_ABORTIFHUNG, 5000, ref dwResult); -
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/SaveFile dialogs, which are currently open.
I'm using C# .NET, Win7.
Status Update #1
As Anders pointed out, there is a simple way to refresh explorer windows using COM:
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.So this part is done. Hovewer I still need to refresh the OpenFile/SaveFile dialogs, and the code above doesn't do that. Does anybody know how to refresh those dialogs?
An important point is that if I change the "Show Hidden Files" in Folder Options in Control panel, those OpenFile/SaveFile dialogs 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...
