Question

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.fMask = 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…

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).
