So, I have a serversocket and I want that no more than N(e.g. N=3) clients to be able to connect to this.
How can I do it?

Grini,

 In your OnConnect event, get the ServerSocket.Connection.Count and check to see if its over 3. If it is then issue a disconnect to the 4th socket.

Good luck with your project!

grini, use this example:

{ var global }
var
  total: integer;

...

procedure TForm1.FormActivate(Sender: TObject);
begin
total:=0;
end;

procedure TForm1.ServerSocket1ClientConnect(Sender: TObject;
  Socket: TCustomWinSocket);
begin
inc(total);
if total > 3 then begin
  socket.Disconnect(total);
  socket.SendText('Error. 3 connections already active.');
 end
else begin
  socket.Accept(total);
  socket.SendText('Connected.');
end
end;

procedure TForm1.ServerSocket1ClientDisconnect(Sender: TObject;
  Socket: TCustomWinSocket);
begin
dec(total);
end;
