This code will send a file out a open socket.

procedure TSendDataThread.SendFile;
var
  SocketStream: TWinSocketStream;
  FileStream: TFileStream;
  StreamInfo: TStreamInfo;
  FileName: string;
begin
  FileName := ExtractFileName(fStreamInfo.StreamStr);
  FileStream := TFileStream.Create(fStreamInfo.StreamStr, fmOpenRead or fmShareDenyWrite);
  SocketStream := TWinSocketStream.Create(frmMain.csMain.Socket, 60000);
  try
    if (not Terminated) and (frmMain.csMain.Active) then
    begin
      try
        StreamInfo.StreamCmd := SENDFILECMD;
        StreamInfo.StreamSize := FileStream.Size;
        StreamInfo.StreamStr := FileName;
        SocketStream.Write(StreamInfo, SizeOf(TStreamInfo));
        SocketStream.CopyFrom(FileStream, FileStream.Size);
      except
        if not(ExceptObject is EAbort) then
          Synchronize(HandleExeption);
      end;
    end;
  finally
    frmMain.csMain.Socket.Close;
    SocketStream.Free;
    FileStream.Free;
  end;
end;

Good luck Bill

if you prefer blocking sockets using Indy then take a look at :
