System tray context menu doesn't disappear

I create a notification icon with:

notifyIcon.cbSize = sizeof(NOTIFYICONDATA);
notifyIcon.hWnd   = mainWnd;
notifyIcon.uID    = 100;
notifyIcon.uFlags = NIF_ICON | NIF_TIP | NIF_MESSAGE;
notifyIcon.hIcon  = LoadIcon(hInstance, MAKEINTRESOURCE(IDI_LOGO));
notifyIcon.dwState = NIS_SHAREDICON;
notifyIcon.uVersion = NOTIFYICON_VERSION;
notifyIcon.uTimeout = 15000;
notifyIcon.uCallbackMessage = APP_MSG_TRAY;
wcscpy_s(notifyIcon.szTip, 127, WTXT_APP_TRAY_TOOLTIP);

Shell_NotifyIcon(NIM_ADD, &notifyIcon);
Shell_NotifyIcon(NIM_SETVERSION, &notifyIcon);

And have a context menu popup on WM_RBUTTONDOWN and WM_CONTEXTMENU like this:

MENUITEMINFO separatorBtn = {0};
separatorBtn.cbSize = sizeof(MENUITEMINFO);
separatorBtn.fMas开发者_如何学Ck = MIIM_FTYPE;
separatorBtn.fType = MFT_SEPARATOR;

HMENU hMenu = CreatePopupMenu();

if(hMenu) {
 InsertMenu(hMenu, -1, MF_BYPOSITION, APP_OPEN_OPTIONS, WTXT_OPTIONS);
 InsertMenuItem(hMenu, -1, FALSE, &separatorBtn);
 InsertMenu(hMenu, -1, MF_BYPOSITION, APP_MSG_EXIT, WTXT_EXIT);

 POINT pt;
 GetCursorPos(&pt);
 SetForegroundWindow(mainWnd);
 TrackPopupMenu(hMenu, TPM_RIGHTBUTTON, pt.x, pt.y, 0, mainWnd, NULL);
 PostMessage(mainWnd, WM_NULL, 0, 0);
 DestroyMenu(hMenu);
}

It works fine, but the context menu doesn't disappear always. Sometimes (often) if you have ie. winamp and my app icons in system tray, if you right click my app and winamp afterwards, bot menus will appear, and my menu won't disappear automatically until you click an item.

Any ideas?

thanks...

To display a context menu for a notification icon, the current window must be the foreground window before the application calls TrackPopupMenu or TrackPopupMenuEx. Otherwise, the menu will not disappear when the user clicks outside of the menu or the window that created the menu (if it is visible).

SetForegroundWindow(hDlg);

TrackPopupMenu(   hSubMenu,
                 TPM_RIGHTBUTTON,
                 pt.x,
                 pt.y,
                 0,
                 hDlg,
                 NULL);

Do not catch WM_RBUTTONDOWN but WM_RBUTTONUP. And of course do not handle both WM_RBUTTONUP and WM_CONTEXTMENU, since they will both get handled and you'd show the context menu twice for every right-click. Showing the menu twice would have the effect you describe: the menu shows up, but doesn't seem to disappear (because it shows up again right away a second time).

There are apps to try to hack around the restrictions of the notification area (tray) API. They'll hook the Explorer window and listen for Windows messages. That lets them do stuff that isn't otherwise possible but it inevitably destabilizes other apps. Getting two context menus is a sure sign of this kind of trouble.

You've got a good lead on what kind of program may do this, it's got an icon. Kill them one by one until you find the evil-doer. Not much you can do about it probably, other than not running it or complaining to the vendor.

You seem to already have both of the documented bugfixes (SetForegroundWindow & WM_NULL) I'd say anything beyond this is a bug in windows.

If you really want to do hacky things, you could probably get the menu window handle in WM_INITMENU* (And I don't mean the HMENU, but the HWND for the menu) and hide that window.
