推荐答案

*不要忘记REFIID对应于您想要的接口:
IID_IPropertySetStorage想要IPropertySetStorage *
IID_IStorage想要IStorage *
*使用后不要忘记释放接口.
*不要忘记仅在返回值(HRESULT)== S_OK的情况下使用使用接口.
看起来更好:

* Dont forget that the REFIID corresponds to the interface you want:
IID_IPropertySetStorage wants IPropertySetStorage*
IID_IStorage wants IStorage*
* Dont forget to release interfaces after usage.
* Dont forget use interfaces only valid if the return value (HRESULT) == S_OK.
This looks better:

IStorage*    pStorage;
IStream*    pStream;
HRESULT      hr;

hr = StgOpenStorageEx
      (
        L"E:\\Root.stg",
        STGM_READ|STGM_SHARE_DENY_WRITE,
        STGFMT_DOCFILE,
        0, NULL, 0,
        IID_IStorage,
        (void**)&pStorage
      );

if(S_OK==hr)
{
  printf("Storage opened");

  if(S_OK==pStorage->OpenStream(L"Rodies.mp3",NULL,STGM_DIRECT | STGM_CREATE | STGM_READWRITE | STGM_SHARE_EXCLUSIVE,0,(void**)&pStream))
  {
    printf("Stream opened");
    pStream->Release();
  }
  else
  {
    printf("Not Opened");
  }
  pStorage->Release();
}

_getch();

祝您好运.

Good luck.

其原因在于IStorage不是有效的对象.您可以向我们展示初始化OpenStream

its becuase IStorage is not a valid object. can you show us the initialization OpenStream
