Ballon-Popups einblenden

[winapi]

Wie kann ich solche Ballon-Popups im Systray (rechts unten bei der Uhr) einblenden lassen?

Grob gesagt:

hwndToolTips = CreateWindow(TOOLTIPS_CLASS,
                            NULL,
                            WS_POPUP | TTS_NOPREFIX | TTS_BALLOON,
                            0, 0,
                            0, 0,
                            NULL, NULL,
                            g_hinst,
                            NULL);
if (hwndTooltip)
{
// Do the standard ToolTip coding. 
    TOOLINFO ti;

    ti.cbSize = sizeof(ti);
    ti.uFlags = TTF_TRANSPARENT | TTF_CENTERTIP;
    ti.hwnd = hwnd;
    ti.uId = 0;
    ti.hinst = NULL;
    ti.lpszText = LPSTR_TEXTCALLBACK;

    GetClientRect(hwnd, &ti.rect);
    SendMessage(hwndToolTips, TTM_ADDTOOL, 0, (LPARAM) &ti );
}
