Generally speaking you can add menu by InsertMenu or AppendMenu.

I can add it, now I'm trying to make it do something.
What's wromg with this code?

BOOL CMainFrame::OnCmdMsg(UINT nID, int nCode, void* pExtra,
                    AFX_CMDHANDLERINFO* pHandlerInfo)
      if (pHandlerInfo == NULL)
                  AfxMessageBox("You Clicked The DynMenu",
                                MB_OK | MB_ICONEXCLAMATION);
                  AfxMessageBox("Hmm", MB_OK);
      return TRUE;
      return CFrameWnd::OnCmdMsg(nID, nCode, pExtra, pHandlerInfo);

The added menu item has the ID WM_MYMENU.
If I run this program and click the menu, I get 4 Hmms, one right after the other.
If I comment out everything between A and B, it works just fine (minus responding to my dynamic item)

How do I add items to a menu on a tooltray icon?
Free Tool: Path Explorer

Shell tray menu doesn't differ from any other menu. When you right/left click on your application icon window associated with shell tray icon is send call back message, you set when you supplied data for icon. LPARAM contains actual message ID(for instance WM_L(R)BUTTONDOWN(UP)). If you want to popup menu in response to this message you do this as usual by
TrackPopupMenu(Ex), passing previously loaded or created menu. The only one trick here is you must call SetForegroundWindow() before TrackPopupMenu and
PostMessage(m_hwndMenuOwner, WM_NULL, 0, 0);

1st, what's wrong with the code that I posted?
2nd, when I add an item to the menu, it shows up in the main window, but not in the tooltray icon. It's menu never changes.
To add menu to shell tray do the following:

1.Add icon and call back message to the shell tray
    BOOL res;
    tnid.cbSize = sizeof(NOTIFYICONDATA);
    tnid.hWnd = hwnd;
    tnid.uID = uID;
    tnid.uFlags = NIF_MESSAGE | NIF_ICON | NIF_TIP;
    tnid.uCallbackMessage = NotifyIcon;
    tnid.hIcon = hicon;
    if (lpszTip)
        lstrcpyn(tnid.szTip, lpszTip, sizeof(tnid.szTip));
        tnid.szTip[0] = '\0';
      // the ADD in the line below ADDS a new icon
      // if it were MODIFY it would change it for the new icon
    res = Shell_NotifyIcon(AddReplaceDelete, &tnid);
    if (hicon)
2.Add message handler for WM_YOURMESSAGE

LONG CYourView::OnOpenEnableMenu(UINT wParam, LONG lParam)
            if (lParam == (LONG)WM_LBUTTONDOWN ||
                  lParam == (LONG)WM_RBUTTONDOWN){
            // connects the pop-up menu to the code
            CMenu menu;
            CPoint pt;
            CMenu* pPopup = menu.GetSubMenu(0);
            ASSERT(pPopup != NULL);      

            pPopup->TrackPopupMenu(TPM_RIGHTALIGN | TPM_RIGHTBUTTON, pt.x, pt.y, this);

            // It is necessary to force a task switch to the application that
            // called TrackPopupMenu at some time in the near future. This can
            // be accomplished by posting a benign message to the window or thread.
      return 0L;

Is the Loadmenu command what adds the command to the tray icon?
And what was wrong with my code?
Loadmenu loads menu from resource. If you need to modify this menu use DeleteMenu to delete menu item(s) or InsertMenu to insert menu item(s).

But why won't the menu items that I add dynamically appear on the tool tray icon menu?
And what was wrong with my code?
