解决方法：在winnt.h中加上以下语句     #define POINTER_64 __ptr64     typedef void *PVOID;   typedef void * POINTER_64 PVOID64;     个人认为最好不去改winnt.h.   有时需要要调整include文件夹的顺序来解决问题，platform SDK中的winnt.h   DDK中的，vc6.0 自带的winnt.h有多个。 dxsdk 中的这些所用到的winnt.h版本不同。     通过调整IDE 工具-> 选项-> 项目vc++目录;包含文件include 的顺序来解决这类问题   使dxsdk需要的winnt.h所在文件夹在最上面。
