this packaga require windows media player 9 or 10是什么意思 This tool require Direct x 9.0 or later “This tool require DirectX 9.0 or later”该怎么办？？？？ require&request 我下载了AMV精灵。但当我打开应用程序时它说This tool require DirectX 9.0 or later这是怎么回事？ REQUIRE和REQUEST的区别 condition case request require demand require和need的区别是什么？ condition与case request require demand demand,command,request,require的细致区别?
