ServerSocket - OnClientRead event.

Posted by Bill Adams on April 15, 2002 at 23:51:20:

I've been reading up on some examples of how to receive data from the connection. Now, here's a snippet from one of the examples i'm looking at:

var
  MsgLen     : integer;
  Buf        : string;
  LenReceived: integer;
begin
  MsgLen := Socket.ReceiveLength;
  SetLength( Buf, MsgLen );
  LenReceived := Socket.ReceiveBuf( Buf[1], MsgLen );
  Buf := Copy( Buf, 1, LenReceived );

Could someone explain what's going on here? I'm slightly confuse as to what's happening and i'm fairly new to Delphi so a simple explanation would be great.
