UEs...General help/advice with reliable TCP client/server for Indy?
I hope this is the right forum to ask if anyone has worked out a suite of INDY-based TCP and UDP client/server pairs for binary data packet transfer.
I have built TCP client and TCP server projects that manage to work, but my learn-as-you-go approach has to be really inefficient and overly cumbersome.
My requirements are based on the data transmission standards for the network environment that we develop for: frame-delimited TCP streaming data packets. I also need to have a client socket that receives a notification if the socket connection is closed by the server side.
As an exampl...Read and Write multiple lines on Indy TCP Server/Client Socket
Hello, I m a newbie to Delphi..i m trying to write a simple chat application in Delphi, but the problem is that i m unable to send the list of the buddies to the connected client. I m writing the list on the socket as follows

the problem what i m facing is that it writes the names on the socket but on the client side i m unable to receive them properly either ...Create a server socket from an existing client socket
I'm using a TTcpClient component to connect to a server (i know the component is deprecated...)
The delphi (windows 32 vcl) application is a client socket (connected to an as400 server socket)
I need to create a second socket in the delphi application that is a server socket (to implement the drawback design pattern)
So i need to create a new connection between the same job on the as400 and the same process in the delphi application, but reversed. (the windows application is this time the server)

I have to applications that need to communicate with each other. Is it practical for both of them to be servers and clients to each other? One of the applications will work primarily as a server and will launch the other application. The newly launched application needs to be able to send occasional information to the server to update information in the application that launched it. Also, if the user attempts to close the launched application it needs to tell the launcher application to close the appl
ication that it launched. Does this sound practical? This is kind of like launching wo...client-server with socket

i have got the multithreaded server example from perldoc but i need a client
that will connect, and upon recieving a certain work from the server, send
some authentication details and the current ip address of the client.
this is for a dynamic dns solution. I need to have the client send and
recieve info to and from the server, but there don't seem to be any examples
of this 2-way conversation.
Mat Harris OpenGPG Public Key ID: C37D5...Pass values from server to client and client to server?
i have a scenario,
i want to pass some values to an image and a label dynamically from database.
i want to use an anchor(a href) tag and when the mouse goes over the anchor , an image url and label text must change with the values from database. Suppose that there are more than one anchor at the page.
One more thing, anchors must get the id values of the records from database at page_Load() and the queries use these these ids again to retreive imageurl and label text values from database when ...Indy for socket server.
I need some general guidance, as I can't locate a good tutorial.
I have been using TServerSocket in my project, but it's giving us some unexpected results in heavily multithreaded environments that I would like to rewrite the app using Indy.
My app basically is a multithreaded, non-blocking server, running as a service (TService). The data connections are rather heavy at times, so I need to make sure that each socket has it's own copy of data (makes sense, right :-)).

I am new to Indy and have done a lot of ready and internet research. I have walked through each 24 pages of threads on this side.
I am using Delphi XE and getting ready to move to Delphi XE3 and need some help with Indy Intercept components.
I can get the Mapped ports to work, however cannot not get the intercepts to work.
I want to use them with both TCP/IP and UDP packets to compress both packets and headers if possible.
Is there a basic example of how to use and intercepts and do I use an IO as part of the solution?

I was playing around with a server trying to get the proper
implementation of client threads to support COM via

TidContext implementations and their related client commands to be able
to utilize COM without issue and think this is the easiest solution..
In the Constructor of the server set a custom scheduler and it seems to
be working great. I haven't messed around with the internals of the
server with a custom TidSchedulerOfThreadDefault before but it seems to
be the way to go. It appears that the TidContex...Indy Server Socket Freezing [Edit]
Hi all, how are you ? I have a little doubt, when I have connected clients and i try to put more ports to listen or close listening ports the form is freezing.
