[aspvbjava]

新建一个工程，并且加入了下面的代码

void PlayMovie(LPTSTR lpszMovie)
{
　IMediaControl *pMC = NULL;
　IGraphBuilder *pGB = NULL;
　IMediaEventEx *pME = NULL;
　long evCode; // something to hold a returned event code
　HRESULT hr = CoCreateInstance(CLSID_FilterGraph, NULL, CLSCTX_INPROC,
　IID_IMediaControl, (void **)&pMC);
　hr = pMC->QueryInterface(IID_IGraphBuilder, (void **)&pGB);
　hr = pMC->QueryInterface(IID_IMediaEventEx, (void **)&pME);
　hr = pGB->RenderFile(lpszMovie, NULL);
　hr = pMC->Run();
　hr = pME->WaitForCompletion(INFINITE, &evCode);
　if(pMC)pMC->Release();
　　if(pGB)pGB->Release();
　　　if(pME)pME->Release();
}

然后加入了CoInitialize(NULL);初始化组件
包含了#include <streams.h>文件
当运行到　
IMediaControl *pMC = NULL;
　IGraphBuilder *pGB = NULL;
　IMediaEventEx *pME = NULL;
上面这几个地方的时候出现错误：
E:\工程\temp\tempDoc.cpp(98) : error C2018: unknown character '0xa1'
E:\工程\temp\tempDoc.cpp(98) : error C2018: unknown character '0xa1'
E:\工程\temp\tempDoc.cpp(99) : error C2018: unknown character '0xa1'
E:\工程\temp\tempDoc.cpp(99) : error C2018: unknown character '0xa1'
等类似的

请问媒体播放还需要包含哪些文件？
