IReposPropertyLarge Interface

This interface is used to handle binary large objects (BLOBs) and large text fields. The IReposPropertyLarge is only available to BLOB and text data. Attempting to use it with other kinds of data will fail.

This interface is intended to be an IDispatch version of some IStream methods.

When to Use

All text and binary fields can publish this interface, regardless of their size.
