EzComm COM DLL
EzComm.NET COM DLL
(Note: the only difference is the Events
interface is optimized for .NET)
The EzComm COM DLL makes it easy to
connect two computers and begin sending messages or files
between them. The messages can be anything - text or
binary data, and the computers can be on the same network
or across the Internet anywhere in the world. Use EzComm
in your VB, C++, .NET or Delphi programs for any applications
that need to send messages or any kind of data, such as eCommerce
applications exchanging XML documents or Instant Messaging
and Chat programs.
What is EzComm and how does it work?
EzComm is a set of COM objects that take care of all of
the low-level TCP/IP work for you, making it easy to begin
exchanging messages immediately. If you've ever tried
writing your own sockets program, you know how much work
is involved in defining and implementing a messaging
system. That's what EzComm does for you, providing a
turn-key messaging solution.
EzComm can be run
on any number of machines - but there is only ever one
connection between a single client and server EzComm
instance. You may be want to connect several PC
together. You can do this using multiple instances of
EzComm. Probably the easiest way to accomplish this is
for one PC to act as "server" for all clients, and for it
to foward all messages it receives from connected clients.
You would write your application code to use and manage
all of the EzComm objects. Each time a new client
connects to the server, it is added to a list of
connections the server maintains. For example, suppose
you have PCs A, B and C, and PC A is acting as server.
You write your server code such that it listens for
incoming connections. When PC B connects, it stores this
connection object in a list, and loops around and waits
for another connection. When PC C connects, it does the
same. When PC B sends a message to the server, you could
write code to forward the message to all connected PCs in
the list. This is only one scenario. You can probably
think of others, such as a peer messaging system.
