PowerNet is an add-on library for client/server application development in Xbase++.

PowerNet library can create Windows sockets that enables Xbase++ programmers to develop advanced Internet, intranet, and other network-capable applications to transmit application data across the wire, independent of the network protocol being used.

PowerNet library provides Xbase++ programming tools for creating client/server applications using Internet technologies. Applications can create servers and clients and perform communication between them using message passing via TCP/IP sockets. On the request of the client, the server can execute the assigned function with passed parameters and return the result of the execution to the client. This makes it possible to create truly distributed applications with remote procedure calls (RPC).

PowerNet functions represent object abstractions of internal server/client classes. The functions encapsulate all functionalities of various Internet protocols, which are defined as function parameters. The functions are generalized and automated and perform internally the logic of the server/client classes. You don't need to know object-oriented programming, classes, methods, properties and events. Instead, use PowerNet functions as building blocks to create short, fast and efficient programs.

PowerNet library supports Alaska Xbase++ V.2.0 to V.1.8.
