    wheelmouse

    I don't know how to show a message if the user wheel the mouse up and close it if he wheels it down

    I do this only to get the same result

    case WM_WHEELMOUSE:
    MessageBox(this->hWnd,L"Message");
    break;

    Thank you

    WM_MOUSEWHEEL
    GET_WHEEL_DELTA_WPARAM Macro
    See if delta negative or positive.
    Best regards,
