    copied!<p>This problem has been afflicting me for quite a while and it's been really annoying.</p> <p>Every time I login after a reboot/power cycle the explorer takes some time to show up. I've taken the step of waiting for all the services to boot up and then I login, but it doesn't make any difference. The result is always the same: Some of the icons do not show up even if the applications have started.</p> <p>I've dug a bit on the code that makes one application "stick" an icon in there, but is there an API call that one can perform so explorer re-reads all that icon info? Like invalidate or redraw or something of the sort?</p> <hr> <p>Apparently, it looks like Jon was right and it's not possible to do it.</p> <p>I've followed Bob Dizzle and Mark Ransom code and build this (Delphi Code):</p> <pre><code>procedure Refresh; var hSysTray: THandle; begin hSysTray := GetSystrayHandle; SendMessage(hSysTray, WM_PAINT, 0, 0); end; function GetSystrayHandle: THandle; var hTray, hNotify, hSysPager: THandle; begin hTray := FindWindow('Shell_TrayWnd', ''); if hTray = 0 then begin Result := hTray; exit; end; hNotify := FindWindowEx(hTray, 0, 'TrayNotifyWnd', ''); if hNotify = 0 then begin Result := hNotify; exit; end; hSyspager := FindWindowEx(hNotify, 0, 'SysPager', ''); if hSyspager = 0 then begin Result := hSyspager; exit; end; Result := FindWindowEx(hSysPager, 0, 'ToolbarWindow32', 'Notification Area'); end;</code></pre> <p>But to no avail.</p> <p>I've even tried with <pre><code>InvalidateRect()</code></pre> and still no show.</p> <p>Any other suggestions?</p>
