The GetMenuItemID function retrieves the identifier for a menu item located at the given position.
hmenu
Identifies the pop-up menu that contains the item whose identifier is to be retrieved.
pos
Specifies the zero-based position of the menu item whose identifier is to be retrieved.
The return value specifies the identifier of the pop-up menu item if the function is successful. If the hmenu parameter is NULL or if the specified item is a pop-up menu (as opposed to an item within the pop-up menu), the return value is –1. If the pos parameter corresponds to a SEPARATOR menu item, the return value is zero.
The following example initializes the items in a pop-up menu:
WORD wCount;
WORD wItem;
WORD wID;
case WM_INITMENUPOPUP:
wCount = GetMenuItemCount((HMENU) wParam);
for (wItem = 0; wItem < wCount; wItem++) {
wID = GetMenuItemID((HMENU) wParam, wItem);
.
. /* Initialize menu items. */
.
}
break;
