Métodos

  Nombre Descripción
Método público Clone Infraestructura. Creates a new stream object with its own seek pointer that references the same bytes as the original stream.
Método público Commit Infraestructura. Ensures that any changes made to a stream object that is open in transacted mode are reflected in the parent storage.
Método público LockRegion Infraestructura. Restricts access to a specified range of bytes in the stream.
Método público RemoteCopyTo Infraestructura. Copies a specified number of bytes from the current seek pointer in the stream to the current seek pointer in another stream.
Método público RemoteRead Infraestructura. Reads a specified number of bytes from the stream object into memory starting at the current seek pointer.
Método público RemoteSeek Infraestructura. Changes the seek pointer to a new location relative to the beginning of the stream, to the end of the stream, or to the current seek pointer.
Método público RemoteWrite Infraestructura. Writes a specified number of bytes into the stream object starting at the current seek pointer.
Método público Revert Infraestructura. Discards all changes that have been made to a transacted stream since the last Commit(UInt32) call.
Método público SetSize Infraestructura. Sets the size of the stream object.
Método público Stat Infraestructura. Retrieves the tagSTATSTG structure for this stream.
Método público UnlockRegion Infraestructura. Removes the access restriction on a range of bytes previously restricted with the LockRegion(_ULARGE_INTEGER, _ULARGE_INTEGER, UInt32) method.
