Hello, Dz.
My application uses socket server for accepting connections to the clients
and send them data. There is data that are sended to some clientes, but to
others no. Every client, in the first step, sends data to the server for
identificating the data that it will receive.
I believe that I need a thread for every client that encapsulates the
reception of initial information and the control over the last data sended.
For this, in this moment, in the principal thread, when there is data, the
clients are tested validating if this data are for them. If it is there, use a
method in ThreadClient, for sending data with Socket.SendStr.
I have:
TThrdSrvClient = class(TWSocketClient) public ThreadClient :
TThreadClient; RcvdLine : String; ConnectTime : TDateTime; end;
for adding the client to socket server.
What do you believe that i must use? TWSocketThrdServer or TWSocketServer?
I thank a lot your suggestions
Regards.
Ana.
