Hello;
I 'm using a serversocket to make dialog beetween one pc and many machines; 
these machines are connecting to my pc via the serversocket Object ; so I 'm 
getting the informations transmitted by the method OClientRead 
(Socket.ReceiveBuf etc...);
Now I 'd like to send an ack to the machine ;so I want to use 
Socket->Connections[x]->SendText etc..
The problem is that I don't know hot to get the value x !
I 've tried with a fix value (0) and it's ok when I have only one machine 
connected ; but whe there are many machines there are many connections so I 
have to know the number of the connection
I have to tell that i 'm usin a nonblocking Servertype

void __fastcall TForm1::ServerSocket1ClientRead(TObject *Sender,
       TCustomWinSocket *Socket)
{
  // Socket is the socket for the actual client.
  // So if you want to send to this specific client use

  ... first read all with Socket->ReceiveBuf()

  .. now send
   Socket->SendBuf ( ... );
}

If you loop through the Connectiones[] array from 0 to
ServerSocket->Socket->ActiveConnectios - 1 you will find that
one of them has the value Socket.

If you are sending the ack from inside the OnClientRead event, then use the
same Socket parameter that you read your data from.
