DelMCEntries
short menuID ; ID of menu to be affected; 0=menubar
short itemID ; item number or -98 for all items in menuID
DelMCEntries removes menu color table information stored for a particular menu and item (or menubar, or all items in a menu).
menuID is the ID of a menu (as used in NewMenu or GetMenu). A value of 0 specifies the menubar.
itemID identifies which menu item to affect. A value of mctAllItems (-98)
deletes the color data for all items in menu menuID. A value of 0
affects the title of menu menuID.
Notes: Data in the variable-length menu color table (see MCTable) is removed and colors for the specified items revert to standard black-on-white. You
might use this call to release some memory in a desperate crunch. Use
DispMCInfo to dispose of all menu-color information. install all the colors. Or if you used GetMenu to load the 'MENU' resource, just supply an 'mctb' resource with the same ID in your application
resource file.
