Remarks
If the high-order word of wParam contains 0xFFFF and the lParam parameter contains NULL, the system has closed the menu.
Do not use the value 1 for the high-order word of wParam, because this value is specified as (UINT) HIWORD(wParam). If the value is 0xFFFF, it would be interpreted as 0x0000FFFF, not 1, because of the cast to a UINT.
