Problems with self-drawing for multiple document menus? ? ? ? ? ? , Very anxious. Please master

Continuous asked several times, and have never had a viable answer.
I would like to draw from the menu program. Before self-painted, you must first get a handle on the current window menus.
According to the handle and then, self-drawing property. And reload the OnDrawItem () and OnMeasureItem () two functions, specifically provided from painted.
But I get the menu using the following two handles, always wrong. (May CMainFrame class)
However, in view OnInitUpdate () function used in error:
CMenu * pMenu = GetMenu (); // pointer can be obtained
HMENU hMenu = pMenu-> GetSafeHmenu (); // get a handle when mistakes? ? ?

My intention is when opening a new document, you get the current menu and then overloads the above two functions, using the obtained handles settings from the painting property, but does not work.
problem:
(1) Why get a pointer to the menu, but the menu was not handle.
(2) When you open a document (click New). No matter what time of the currently loaded document. You can get the current menu, and set the self-painted property. How to achieve? ? ? Thank you

void CMainFrame :: OnInitMenu (CMenu * pMenu)
{
CFrameWnd :: OnInitMenu (pMenu);
Ranch
CMenu * pSubMenu;
UINT nCount, nSubCount, nID;
nCount = pMenu-> GetMenuItemCount (); // Number of columns of submenu
for (UINT i = 0; i <nCount; i ++)
{
pSubMenu = pMenu-> GetSubMenu (i);
nSubCount = pSubMenu-> GetMenuItemCount (); // The number of menu menu items in this column
for (UINT j = 0; j <nSubCount; j ++)
{
nID = pSubMenu-> GetMenuItemID (j);
// Add MF_OWNERDRAW flag to all menus in the frame menu
pSubMenu-> ModifyMenu (j, MF_BYPOSITION | MF_OWNERDRAW, nID);
}
}
}

If you follow the steps above, the first time (without opening a sub-window) is to draw the main frame menu. After opening the sub-window, the menu changes. At this time, the program does not execute the DrawItem function to redraw itself (it has already been drawn once when displaying the main menu). Only displayed when the mouse moves over it
