g.As you mentioned earlier, these common errors for Shell_NotifyIcon occur when the main communication with Explorer times out or occurs before Explorer listens. As mentioned in the comments on Shell_NotifyIcon, GetLastError usually returns ERROR_TIMEOUT (legacy error code inherited from internal SendMessageTimeout call) on timeout.

I am writing an application that runs in the background and I want to place an icon in the notification area so that the user can interact with the element from time to time. The app is currently working fine on my development desktop, but I’m also working on a different laptop. Machine too, and I noticed that calling Shell_NotifyIcon with NIM_ADDalways fails and GetLastError returns ERROR_NO_TOKEN 1008:. Windows 7 SP1 works on both machines

However, the problem seems to be related to a good download timeout. My application really crashes when debugging, otherwise the computer will fail Completely idle.

What is the likely cause? By itself cannot find any information about our own error code, at least nothing related to Shell_NotifyIcon. I am following the best practices for each target operating system in terms of the lpdata parameter, most of these values initialized like this:

 // NOTICEZeroMemory (& m_nid, sizeof (NOTIFYICONDATA));// Get the Shell32 version number and set the size of this structure.// http://msdn.microsoft.com/en-us/library/bb773352%28v=vs.85%29.aspxULONGLONG version matches GetDllVersion (_T ("Shell32.dll"));if (version> = MAKEDLLVERULL (6,0,6,0))m_nid.cbSize = sizeof (NOTIFYICONDATA);m_nid.uVersion = NOTIFYICON_VERSION_4;otherwise, if (version> = MAKEDLLVERULL (6,0,0,0))m_nid.cbSize = NOTIFYICONDATA_V3_SIZE;m_nid.uVersion = NOTIFYICON_VERSION_4;otherwise, if (MAKEDLLVERULL version (5,0,0,0))M_nid> = .CbSize = NOTIFYICONDATA_V2_SIZE;m_nid.uVersion = NOTIFYICON_VERSION;anotherm_nid.cbSize = NOTIFYICONDATA_V1_SIZE;m_nid.uVersion = 0;m_nid.uFlags = NIF_ICON | NIF_TIP | NIF_MESSAGE | NIF_SHOWTIP;// Only Windows 7 or later systems can use the GUID to identify the notification icon.if (IsWin7OrLater ())= NIF_GUID;m_nid.guidItem = NOTIFICATION_ICON_GUID;anotherm_nid.uID = NOTIFICATION_ICON_ID;// Window for notification about a set of trays:m_nid.hWnd = m_hWnd;m_nid.uCallbackMessage = UM_TRAYNOTIFY;// Define the icon bar and tooltip:m_nid.hIcon corresponds to the App.Tooltip loading icon (idr_mainframe);// displayed if the mouse was always over the symbol.
