The CreatePopupMenu function creates a drop-down menu, submenu, or shortcut menu. The menu is initially empty. You can insert or append menu items by using the InsertMenuItem function. You can also use the InsertMenu function to insert menu items and the AppendMenu function to append menu items.
HMENU CreatePopupMenu(VOID)
This function has no parameters.
If the function succeeds, the return value is the handle to the newly created menu.
If the function fails, the return value is NULL. To get extended error information, call GetLastError.
The application can add the new menu to an existing menu, or it can display a shortcut menu by calling the TrackPopupMenuEx or TrackPopupMenu functions.
Resources associated with a menu that is assigned to a window are freed automatically. If the menu is not assigned to a window, an application must free system resources associated with the menu before closing. An application frees menu resources by calling the DestroyMenu function.
