Aristoline - Socket

Overview

Socket is an ActiveX component (provided by the SocketSet ActiveX control) that enables the development of TCP and UDP applications (as clients and servers) using Windows Sockets. You can use any development tool that supports the use of ActiveX Contols and Automation (Visual Basic, Visual C++, Access, Delphi etc). It mirrors the underlying API and provides access to virtually all of the API functionality. The following is a summary of its features:

Enables the use of TCP Stream and UDP Datagram sockets (as clients and servers).
Sockets can be blocking or asynchronous. In asynchronous mode the underlying notification messages are passed to your application as events.
Inactivity timer for detecting dead sockets (i.e. sockets where the connection has been lost but there has been no notication of this).
Hides all the underlying data structures - these are replaced by properties.
Selection of send and receive methods enabling data to be handled as string and/or byte arrays.
Access to most of the underlying API (see list below for API functions supported).
Access to the underlying Socket handle enabling the use of API functions not encapsulated in Socket.
