Metodo pubblico LockRegion Infrastruttura. Restricts access to a specified range of bytes in the stream.
Metodo pubblico RemoteCopyTo Infrastruttura. Copies a specified number of bytes from the current seek pointer in the stream to the current seek pointer in another stream.
Metodo pubblico RemoteRead Infrastruttura. Reads a specified number of bytes from the stream object into memory starting at the current seek pointer.
Metodo pubblico RemoteSeek Infrastruttura. 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.
Metodo pubblico RemoteWrite Infrastruttura. Writes a specified number of bytes into the stream object starting at the current seek pointer.
Metodo pubblico Revert Infrastruttura. Discards all changes that have been made to a transacted stream since the last Commit(UInt32) call.
Metodo pubblico SetSize Infrastruttura. Sets the size of the stream object.
Metodo pubblico Stat Infrastruttura. Retrieves the tagSTATSTG structure for this stream.
