Hello List !
I have actually started working on this side project, an experiment
really - a chat client/server.
There are of course some really great examples, from which I am
borrowing a fair bit of code ;)
(A few more comments throughout the sample projects wouldn't hurt :>).
What I want to try
and understand a bit better is how/why the use of a delimiter is
necessary - it looks as though
the EZprotocol uses chr(252) as a marker. Shouldn't there be some way
when creating my own
TCPSocket class, that there is some property or method I can create that
knows (via the TCP
protocol/socket in and of itself?) where the beginning and/or end of a
particular data stream is ?
Also how much data can the socket buffer for me ? In other words, if I
peek in on it periodically,
and wait until I find *two* occurrences of my marker - how much data is
that ? I'm expecting the
chunks of data to be fairly small most of the time - easily fitting in a
single TCP packet .. but say
something like theoretically having to transfer a *large* userlist back
to the client .. I'm in two
minds about how to work this out. I'm thinking it may be a bad idea to
attempt to break it down
to discrete blocks of data, (although this seems like a simpler way to
tackle it) - and instead be sure
that the client/server can 'stream' large data sets correctly. The data
is presented serially after all.
I consider myself to still be relatively new to RB although I own 5.5.5
and 2005R4 Professional
licenses - Windows. I should mention that I'm a big fan of RB, and of
these lists, and all the clearly
very talented people who frequent them :) I switched from VB6 as soon as
I discovered it! I have
found it to be an incredibly useful tool, although I largely use it for
my own custom work related
needs - this project is just for fun :)
