Métodos

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