Streams over a TCP/IP socket

I need a good TCP/IP unit that is capable of sending streams thru the socket.

A simple example of a GetStream() and PutStream() would be sufficient.

I'd like to use the TCP/IP components that come with Delphi 4.

IDeally, I'd like to use TReader and TWriter to read and write to a socket rather then a stream.

Well something like that...

There is a sample coming with delphi ( chat example) where is in use the sending of a string. In stead of string you just have to send a stream ( array of char- buffer).
To make the simplest check just change the functions in the example using StrPas on receiving and StrPCopy on sending to transform the strings to buffer.

Have a good day

get ICS (fpiette's *free* components)
they are really great.. better than the components
coming with delphi, you can use UDP, TCP etc...
and send streams or strings..

it comes with a lot of well explained demos
and full source

I have fpiette's routines.  I even use them.  I just wanted a simple routine to send a tstream in tact.  I can do this myself as I am not a newbie, but I wanted to see what other people came up with.  This is considered a very low value post coming from me as most questions I make worth in upwards of 500 each.

var
      S : TStream;
      C      :      Pointer;
begin
      S      :=      TFileStream.Create('c:\file2',fmCreate);
      GetMem(C,Socket.ReceiveLength);
      Socket.ReceiveBuf(C^,Socket.ReceiveLength);
      S.Write(C^,Socket.ReceiveLength);
      FreeMem(C);
      S.Free;
end;
