楼主请注意！本人实现了C脚本的代码了：
其他说明和上面一样
播放的代码：
#define GetObject GetObject

__object *pdl = NULL;
__object *pic = NULL;
__object *obj = NULL;

pdl = __object_create("PDLRuntime");
pic = pdl->GetPicture("");
obj = pic->GetObject("mplayer_control");

obj->FileName="H:\\MUSIC01.DAT";
obj->Play;

__object_delete(obj);
__object_delete(pic);
__object_delete(pdl);

停止的代码：
#define GetObject GetObject

__object *pdl = NULL;
__object *pic = NULL;
__object *obj = NULL;

pdl = __object_create("PDLRuntime");
pic = pdl->GetPicture("");
obj = pic->GetObject("mplayer_control");

obj->FileName="H:\\stop.DAT";
obj->Play;

__object_delete(obj);
__object_delete(pic);
__object_delete(pdl);
请注意：停止的原理是播放一段暂短的没有声音的文件！
以上代码在wincc v6.0和win2000中测试通过！
