Socket/X
-
Version
2.00.016
Socket/X provides you with full access to the power of
Windows Sockets, making it easy to write TCP/IP or UDP
client and server software. Socket/X comes in
ActiveX control and COM object forms. Because
Socket/X is both an ActiveX control and a COM object,
you can use it nearly anywhere -- ASP pages, Visual
Basic applications, Visual C++ applications, anywhere
that supports either COM objects or ActiveX controls.
Socket/X provides complete support for Windows and
Visual Basic's event-driven programming model and lets
you do nearly anything that can be done with WinSock.
Socket/X goes beyond the normal Visual Basic event-
driven model by providing a scheme for Fast
Notifications. Fast Notifications allow your program
to quickly receive events through simple functions,
rather than going through the lengthy process to fire
an event. Fast Notifications considerably reduce the
amount of time required to handle an event and only
require a couple extra lines of code on your part.
Want to stick with events? No problem! Those are still
supported.
You can also use Socket/X in a "blocking" mode. This
enables you to use Socket/X where events and callbacks
are impractical (such as ASP pages).
Socket/X supports stream-based and datagram sockets.
Stream-based sockets provide sequenced, reliable, full-
duplex, connection-oriented byte streams. With stream-
based sockets your data is guaranteed to arrive. This
uses the Transmission Control Protocol (TCP) for the
Internet address family.
Datagram sockets are connectionless, unreliable
packets (typically small) of a fixed maximum length.
These kinds of sockets are good for broadcasting large
quantities of small pieces of information to a lot of
clients. This style of socket uses the User Datagram
Protocol (UDP) for the Internet address family.
