Hello,
is it possible to send a tray message, like an update information, to the system try by windows api?
I see some software products use a total overhead with codejock or similar. But others seems to use a simple message with a common windows style, like the good old bubble tooltip on XP.

So if you have  sample code or a link to a good tuturial, you are my hero.

You will  like http://www.codeproject.com/KB/dialog/MessageBalloon.aspx for it's sheer simplicity:
struct MessageBalloon : public NOTIFYICONDATA
{
    MessageBalloon(LPCTSTR _szInfo = _T("Prompt"), LPCTSTR _szInfoTitle = 0, 
        LPCTSTR _szTip = 0, HICON _hIcon = 0)
    {
        static struct wnd_holder{
            HWND hwnd_;
            wnd_holder(){hwnd_ = CreateWindowW(L"STATIC", 0, 0, 0, 0, 0, 0, 0, 
                0, 0, 0);}
            ~wnd_holder(){DestroyWindow(hwnd_);}
        } wh;

        memset(this, 0, sizeof(*this));
        cbSize = sizeof(*this);
        hWnd = wh.hwnd_;
        hIcon = _hIcon ? _hIcon : 
           ::LoadIcon(::GetModuleHandle(NULL),
           MAKEINTRESOURCE(128/*IDR_MAINFRAME*/));
        if (! hIcon) hIcon = ::LoadIcon(NULL, IDI_INFORMATION);
        uFlags = NIF_INFO | NIF_TIP | NIF_ICON; 
        dwInfoFlags = NIIF_INFO;
        _tcscpy(szInfo, _szInfo);
        if (! _szInfoTitle) LoadString(::GetModuleHandle(NULL), 
            57344/*AFX_IDS_APP_TITLE*/, szInfoTitle, sizeof(szInfoTitle));
        else _tcscpy(szInfoTitle, _szInfoTitle);
        _tcscpy(szTip, _szTip ? _szTip : szInfoTitle);

        Shell_NotifyIcon(NIM_ADD, this);
    }

    ~MessageBalloon(){Shell_NotifyIcon(NIM_DELETE, this);}
};
