Thanks very much for the reply and help. So i understand... Assumed the sever is listening... In tcp proto. 1) connect the client 2) in Client.SessionConnected event : send the string 3) In Client.Datasent event : client.closedelayed But then for a response Is this correct ? 1) In server.DataAvailable event : server : ClientServer.sendstring response; 2) In Server : ClientServer.Datasent event : server.clientserver.closedelayed balbaro > Send TWSocket mailing list submissions to > twsocket@elists.org > > To subscribe or unsubscribe via the World Wide Web, visit > http://www.elists.org/mailman/listinfo/twsocket > or, via email, send a message with subject or body 'help' to > [EMAIL PROTECTED] > > You can reach the person managing the list at > [EMAIL PROTECTED] > > When replying, please edit your Subject line so it is more specific > than "Re: Contents of TWSocket digest..." > > > Today's Topics: > > 1.
