PORefresh Windows Explorer in Win7
text
Body
copied!<p>My program sets <code>"HKCU\Software\Microsoft\Windows\CurrentVersion\Explorer\Advanced"</code> value <code>"Hidden"</code>. Hovewer I'm not able to refresh the explorer to take into account this change. I've tried:</p> <p>1) </p> <pre><code> SHChangeNotify(SHCNE_ASSOCCHANGED, SHCNF_IDLIST, IntPtr.Zero, IntPtr.Zero);` </code></pre> <p>2)</p> <pre><code> SHELLSTATE state = new SHELLSTATE(); state.fShowAllObjects = (uint)1; SHGetSetSettings(ref state, SSF.SSF_SHOWALLOBJECTS, true); </code></pre> <p>3) </p> <pre><code> SendMessageTimeout(HWND_BROADCAST, WM_SETTINGCHANGE, SPI_SETNONCLIENTMETRICS, 0, SMTO_ABORTIFHUNG, 5000, ref dwResult); </code></pre> <p>4) </p> <pre><code> SendMessage(HWND_BROADCAST, WM_COMMAND, 28931 /* Refresh */, 0); </code></pre> <p>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 <code>OpenFile</code>/<code>SaveFile</code> dialogs, which are currently open.</p> <p>I'm using C# .NET, Win7.</p> <h2>Status Update #1</h2> <p>As <code>Anders</code> pointed out, there is a simple way to refresh explorer windows using COM:</p> <pre><code>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(); </code></pre> <p><del>So this part is done.</del> Hovewer I still need to refresh the <code>OpenFile</code>/<code>SaveFile</code> dialogs, and the code above doesn't do that. Does anybody know how to refresh those dialogs?</p> <p>An important point is that if I change the "Show Hidden Files" in Folder Options in Control panel, those <code>OpenFile</code>/<code>SaveFile</code> 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...</p> <h2>Status Update #2</h2> <p>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?</p>
