<p>copied from forum</p> <p><b>New page</b></p><div>This package is designed to help you build client and multi-client servers in Visual Prolog CE 7. <br /> <br /> SCS (Simple Client Server) uses a native binding to a subset of winsock2 functions and does not use sockbind or mgslayer (at all). <br /> <br /> It is designed with multithreading in mind : a server (instance of scsServer class) waits for incoming connections in a thread. A connection is managed by a callback predicate that you provide. An instance of scsClient can then be used to communicate with the client. <br /> <br /> The sending of data is a blocking process, but the reception is performed by a listening thread that triggers another callback predicate, passing the data received as argument. <br /> <br /> The design is very similar to a standard client/server scheme. <br /> <br /> Two different modes are supported : <br /> <br /> In the nibble_mode, the reception callback predicate is evaluated as soon as data is available. This doesn&#039;t mean you get the data that has been sent : you get pieces of data as soon as it arrives. <br /> <br /> In the message_mode (default mode), SCS adds a data management system that only triggers the reception callback when the data reception is complete - this means that you do not have to take care of the rebuilding of complete data : SCS does it for you. <br /> <br /> The &#039;transmitFile&#039; function of winsock2 is supported. This means that you can even send files (see msdn for transmitFile in winsock2). <br /> <br /> A tutorial can be found there : <br /> <br /> http://www.arsaniit.com/vp_tools/scs.htm <br /> <br /> You&#039;ll also find the documentation of the classes in a prodoc format (ie the Visual Prolog Help) at the same page. <br /> <br /> The demo project shows how to build a time server (that sends the server&#039;s time to a client and closes the cnx) and a reverse server (that sends back reversed string until it receives the string &#039;end&#039;). <br /> <br /> The demo project features a simple client featuring a console with sending/receving monitoring. <br /> <br /> The download link : http://www.arsaniit.com/vp_tools/download/scs_17.zip<br /> <br /> :[[Image:3rd-SCS-Simple Client Server.png]]</div>
