interface IBinaryPropertyBag : IUnknown
Remarks
Includes methods that enable the document parser to access values in a property bag as binary data. Use the QueryInterface method of an object that implements the IParserPropertyBag Interface to get an interface pointer, as shown in the following example.
STDMETHODIMP TDP::Parse(
ILockBytes *pilb,
IParserPropertyBag *pipbag,
VARIANT_BOOL *pfChanged)
{
HRESULT hr = E_FAIL;
IBinaryPropertyBag* pibbag = NULL;
BYTE* pbVal = NULL;
unsigned int cbVal = 0;
//
// Code omitted.
//
hr = pipbag->QueryInterface(IID_IBinaryPropertyBag, (void**)&pibbag));
hr = pibbag->GetBytes("vti_fileformatmetainfo", &cbVal, &pbVal);
//
// Code omitted.
//
}
