PowerCom is an add-on library for client/server application development in Xbase++. PowerCom library is function-oriented and implements top-down modular style of programming. Functions and their parameters are very flexible, user-friendly, intuitive and easy to use.
PowerCom 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.
PowerCom 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).
PowerCom library can create servers and clients for various Internet protocols: TCP/IP, SMTP, POP3, FTP, HTTP, WebSocket and TLS. PowerCom functions implement Internet protocols according to the respective RFC specifications.
PowerCom 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 PowerCom functions as building blocks to create fast and efficient programs with a minimum number of code lines and that use the minimum amount of memory resources.
PowerCom library contains multiple modules listed in the following table.
| Module | Description |
| PowerComSck | Socket |
| PowerComTcp | TCP/IP server/client |
| PowerComMail | Mail clients |
| PowerComFtp | FTP client |
| PowerComHttp | HTTP server/client |
| PowerComWs | WebSocket server/client |
| PowerComTls | TLS client |
PowerCom library supports Alaska Xbase++ V.2.0 to V.1.8. It is available in Serbian and English language, but can be easy modified by the user in any language.
Demo program of PowerCom library with complete documentation and examples can be downloaded on the Download page.
