Méthodes

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