[求助]编译的时候出现这个问题，一支解决不了，
- e:\henway 2\gameengine.cpp(425) : error C2065: 'DWORD_PTR' : undeclared identifier
e:\henway 2\gameengine.cpp(425) : error C2677: binary '&' : no global operator defined which takes type 'struct tagMCI_OPEN_PARMSA' (or there is no acceptable conversion)
e:\henway 2\gameengine.cpp(438) : error C2677: binary '&' : no global operator defined which takes type 'struct tagMCI_SEEK_PARMS' (or there is no acceptable conversion)
e:\henway 2\gameengine.cpp(446) : error C2677: binary '&' : no global operator defined which takes type 'struct tagMCI_PLAY_PARMS' (or there is no acceptable conversion)
执行 cl.exe 时出错.
实验.exe - 1 error(s), 0 warning(s)
第425行是：if (mciSendCommand(NULL, MCI_OPEN, MCI_OPEN_TYPE | MCI_OPEN_ELEMENT,
(DWORD_PTR)&mciOpenParms) == 0)
为什么会出现这呢，
