Description
Changes information about a menu item.
Remarks
The application must call the CMenu.DrawBar function whenever a menu changes, whether the menu is in a displayed window. SetItemInfo does this call internally.
In order for keyboard accelerators to work with bitmap or owner-drawn menu items, the owner of the menu must process the WM_MENUCHAR message.
