automation server to client and client to serverI 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...

c# server
I have serious problems with web-services. I implement this scenario:
I developed a web-service in c# using VS2005. Here is my test method:
[WebMethod] public string TwoStrings(string one, string two) { return one + two; }
When I use the web-service using a c# client it works. But when I use it with a delphi client, it returns always null. I used a SoapExtension to compare two requests. There are some differents:

Start Client Timer from Server Event and start server Event from client event
All of you, I have a big challenge which i'm not able to resolve.
I need some experts with samples on this.
Situation for a webbased quiz system I have a data set with e.g. 5 questions.
The process should be like
1. Load Question 1 from database, there is also a picture and a MP3 sound file
2. I connect the MP3 sound file to a webcontrol I've written to play Mp3 with a flashmovie.
3. Once this mp3 is played (the question is read for people with reading problems) an Event should be raised from the client to the server.
4. The event from 3 should start a Countdown timer (15 se...

Client-server to thin clientHi all,
we have a robust client-server application (PB 11.2, 70
pbls, 2000 objects) and a huge task to rebuild our
application to be a thin client, where as a client side we
are considering to use existing PB application GUI or Web
Browser.
We are about to make a big decision which way to go, so
please recommend us what are the current possibilities now,
in 2010, and what are the pros and cons.
(Rewriting our application is not an option for us.)
We are considering:
- Appeon
- Deploying PB nonvisuals to EAserver and use existing PB
GUI as client
- Migrating to .NET world with...
UDP client-server (Indy 9) [Edit]Hi!
I have a confusing problem using Indy 9 UDP client-server components (Turbo C++ 2006 Pro). I want to create a comunication where client sends a number to server and server returns to him the same number incremented by 1.
void __fastcall TForm1::Button1Click(TObject *Sender)
{
int n = 5, m;
// C1->Host = "127.0.0.1";
// C1->Port = 12000;
C1->SendBuffer(&n, sizeof(n));
C1->ReceiveBuffer(&m, sizeof(m));
Application->MessageBoxA(IntToStr(m).c_str(), "Client got...", 0);

How to receive UDP packets from a broadcast server/client?Hello all,
I do have a server/client app what is sending UDP packets on a specific port.
I can receive those packets with a TIdUDPServer component, but the problem is I can only start 1 app on a PC and I need several more (different) apps on the same computer listening to the UDP broadcast.
How can I resolve this?
Thanks in advance for your answers.
Regards,
Henk.

Server to Client server responsesHello all,
So now we have the client to server part down we need to decide the
server to client. How will we notify the client for success/fail and we
need to develop it in such a way that future "extensions" can add to it.
For fail conditions we should send the standard 401 Unauthorized http
response with the body being a message for the user using Content-Type:
text/plain.
For success conditions we send the standard 200 OK http response with the
body being plain text content type like the error condition but encoded in
such a way the client can parse it easi...
Reading a TDataset from a REST server in a Delphi ClientHi,
I wrote a REST Server in XE2 - that generally works fine - and I am able to use it from a Javascript client.
We also wanted to use it in a Delphi client - and I have never written code with a Delphi client that accepts a dataset from a REST server.
Basically, when I call my proxy (my Delphi code is in Delphi XE, where our client application is) - I get an error message, EDatabaseError 'Missing query, table name or procedure name'
Any ideas what this is all about? I tried to replace the TDataset with a TClientDataset and the problem is the same.
Any ideas where to con...

Anyone using Delphi clients with Python socket servers?Hi,
Just wondering if anyone is using Delphi clients (indy or synapse) with Python based servers using threads or select from a single process.
I have been playing around with Python as the server because its fairly similar to Delphi and runs on every OS. I have made a CRLF based server and a Synapse based client for sending and receiving popup notifications. So far the combo is great, but I am really wondering if anyone has done anything with sending streams(files or other binary data) from delphi to a Python server and how it was handled.
