WORD GetMenuState(hMenu,wId,wFlags)
This function obtains the number of items in the pop-up menu associated with the menu item specified by the wId parameter if the hMenu parameter identifies a menu with an associated pop-up menu. If hMenu identifies a pop-up menu, this function obtains the status of the menu item associated with wId.
| Parameter | Type/Description | |
| hMenu | HMENU Identifies the menu. | |
| wId | WORD Specifies the menu-item ID. | |
| wFlags | WORD Specifies the nature of the wId parameter. If the wFlags parameter contains MF_BYPOSITION, wId specifies a (zero-based) relative position; if wFlags contains MF_BYCOMMAND, wId specifies the item ID. |
The return value specifies the outcome of the function. It is –1 if the specified item does not exist. If the menu itself does not exist, a fatal exit occurs. If wId identifies a pop-up menu, the return value contains the number of items in the pop-up menu in its high-order byte, and the menu flags associated with the pop-up menu in its low-order byte; otherwise, it is a mask (Boolean OR) of the values from the following list (this mask describes the status of the menu item that wId identifies):
| Value | Meaning | |
| MF_CHECKED | Checkmark is placed next to item (pop-up menus only). | |
| MF_DISABLED | Item is disabled. | |
| MF_ENABLED | Item is enabled. | |
| MF_GRAYED | Item is disabled and grayed. | |
| MF_MENUBARBREAK | Same as MF_MENUBREAK, except for pop-up menus where the new column is separated from the old column by a vertical dividing line. | |
| MF_MENUBREAK | Item is placed on a new line (static menus) or in a new column (pop-up menus) without separating columns. | |
| MF_SEPARATOR | Horizontal dividing line is drawn (pop-up menus only). This line cannot be enabled, checked, grayed, or highlighted. The lpNewItem and wIDNewItem parameters are ignored. | |
| MF_UNCHECKED | Checkmark is not placed next to item (default). |
