To disable a menu item(ex. the exit in the file menu), do this:

	call	GetMenu,[win_handle]
	call	GetSubMenu,eax,0      ; index of drop-down menu
	mov	ebx,eax
	call	GetMenuItemID,eax,5   ; index of item in menu
	call	EnableMenuItem,ebx,eax,MF_GRAYED
	call	DrawMenuBar,[win_handle]

To disable a whole drop down menu(ex. the whole file menu), do this:

	call	GetMenu,[win_handle]
	mov	ebx,eax
	call	GetSubMenu,eax,0      ; index of drop-down menu
	call	EnableMenuItem,ebx,eax,1
	call	DrawMenuBar,[win_handle]
