Flags

[This is preliminary documentation and subject to change.]

The pdwFlags parameter allows the IFilter implementation to pass information back to the caller. Currently, the only valid flag is:

IFILTER_FLAGS_OLE_PROPERTIES

This flag indicates that the caller should use the IPropertySetStorage and IPropertyStorage interfaces to locate additional properties. When this flag is set, properties available via OLE property enumeration should not be returned from IFilter.

If OLE properties should not be enumerated, then pdwFlags should be set to zero.
