NOTIFICATIONS
=============

Notify(dataobject, event, arg, param);
    For all the MMC_NOTIFY_TYPE events,
    dataobject
        For single select:
            dataobject for cookie, can be NULL when dataobject is not required
        For multi select:
            Console supplied data object. Supports only one format (CCF_MULTI_SELECT_SNAPIN),
            which can be used to accquire an IUnknow to the primary snapin.
    event = one of the MMCN_NOTIFY_TYPEs
    arg and param depend on type, see below.

MMCN_ACTIVATE
    Is sent when a window is being activated or deactivated.
    arg = TRUE if window is activated, false otherwise.
    param = Not used.

MMCN_ADD_IMAGES
    Sent to IComponent to add images for the result pane. The primary snapin
        should add images for both folders and leaf items. Extension snapins
        should add only folder images.
    arg = ptr to result panes IImageList.
    param = HSCOPEITEM of selected/deselected item

MMCN_BTN_CLICK
    This message is sent when a user clicks on a button.
    arg   = When sent to ExtendControlbar it is the data object of currently selected,
            when sent to IComponent/IComponentData it is 0.
    param = CmdID of the button equal to a value of the MMC_COMMANDS enum type.

MMCN_EXPAND
    arg = TRUE => expand, FALSE => contract
    param = parents HSCOPEITEM.

MMCN_MINIMIZED
    Is sent when a window is being minimized or maximized.
    arg = TRUE if minimized, false otherwise.

MMCN_PROPERTY_CHANGE

MMCN_REMOVE_CHILDREN
    Informs the snapin to delete all the cookies it has added below.
    arg = HSCOPEITEM of the node whose children needs to be deleted.
    param = unused.
    return = unused.

MMCN_RENAME
    This gets called the first time to query for rename and a
    second time to do the rename.  For the query S_OK or S_FALSE for the
    return type.  After the rename, we will send the new name with a LPOLESTR.
    arg = 0 for query, 1 for rename action
    param = LPOLESTR for containing new name
    return = S_OK to allow rename and S_FALSE to disallow rename.

MMCN_SELECT
    If sent to IComponent::Notify:
        arg:
            BOOL bScope = (BOOL) LOWORD(arg);
            BOOL bSelect = (BOOL) HIWORD(arg);
                bScope:     TRUE if an item the scope pane is selected,
                            FALSE if an item in the result pane is selected.
                bSelect:    TRUE if the item is selected,
                            FALSE if it is de-selected.
        param:
            Ignored.

    If sent to IExtendControlbar::ControlbarNotify:
        arg:
            BOOL bScope = (BOOL) LOWORD(arg);
            BOOL bSelect = (BOOL) HIWORD(arg);
                bScope:     TRUE if an item the scope pane is selected,
                            FALSE if an item in the result pane is selected.
                bSelect:    TRUE if the item is selected,
                            FALSE if it is de-selected.
        param:
            LPDATAOBJECT pDataobject = (LPDATAOBJECT)param;
            pDataobject data object of item getting selected/de-selected.
