SetMenu function (winuser.h)
Assigns a new menu to the specified window.
C++
BOOL SetMenu(
[in] HWND hWnd,
[in, optional] HMENU hMenu
);
[in] hWnd
Type: HWND
A handle to the window to which the menu is to be assigned.
[in, optional] hMenu
Type: HMENU
A handle to the new menu. If this parameter is NULL, the window's current menu is removed.
Type: BOOL
If the function succeeds, the return value is nonzero.
If the function fails, the return value is zero. To get extended error information, call GetLastError.
The window is redrawn to reflect the menu change. A menu can be assigned to any window that is not a child window.
The SetMenu function replaces the previous menu, if any, but it does not destroy it. An application should call the DestroyMenu function to accomplish this task.
