Chat program in release 4.7c

hi guys,
I was wondering how one can create a chat program in abap. As its possible in Java & .Net why an abaper under estimate himself. Now here imagine a simple chat program where one can send some text from his SAP GUI which will appear on others SAP GUI and viceversa. Dont think about some messangers like yahoo or gtalk.(dont over estimate being an abaper)
So i developed two programs one to send text & other to receive text. Send prg. is module pool and receive prg. is a simple report which has timer class which gets data from table every second so user dont have to press any button to receive the message.
To start chat you have to run both programs in your GUI where from send program you enter your name in one text field and your message in other text field by pressing enter it gets update in table field(not every time it insert new record, it simply update previous so table size would not increase). As the person with whoem you are chatting is also running both programs, your message appears in 2nd program on his GUI & yours also. followed by your name.
Both chat programs works fine with more then two users also. i tried to combine both program in one screen so user can send & receive chat from one screen. but due to timer class used, its not possible as receive program keeps refreshing for every 1 second.
so i am wondering is thier any way to run one modulepool program & one report in a single screen. some thing like screen splitting or docking???
you are welcome to share your ideas regarding chat in ABAP/4(release 4.7)
Regards,
SUDHIR MANJAREKAR

Yes, thats right. There are few ABAP codes which you can find in the net and can improvise on that.
The program displays list of all users who are currently active on a list.
You can select user and select press button on the application tool bar to send a message.
Concerns here are: 1. The receiver cannot reply from the same popup. He has to run the program, select the user who has send message and reply. 2. You will not be able to see the entire message log.
For logging messages you can try creating standard text for tracking dialog between any two user and something of that sort.

Voice chat program

After a few days work, I have completed the mian voice chat program. I know there are so many people like me that wants that. I post these program. i will complete gui work later. and there is a problem in the program. if the speaking one do not speak for a while, the listening client will hear noise. Can some one help me.

What is the best Videoing Chatting program to use for my Macbook Pro?

I have had Skype for a while now and recently I updated to Skype 5, and the call qaulity is absolutely miserable, it keeps being blurry and freezing and it's a pain to try and talk through. So I was wondering is there any changes or fixes I can do to possibly make it better or improve the quality of my calls? If not is there any other good video chatting programs with good call qualities for Mac?
Im using Skype on my macbook pro, just saying.

How can you check if your wifi is good enough for a quality video call?
Yes I would post on Skypes forum, but there people their are not very helpful or supportive, so Im trying to get other people's opnions on ways to improve the call quality or find a better program.
Does anyone use any other video calling program that is just as good if not better? If so could you please mention it. I've looked on Google and I know some of the softwares or programs out there, but Id like to get peoples first hand experience with the programs and what they think of some of them out there.

Disconnected from ANY chat program when I go into sleep mode

I am using an airport express connection with road runner. When my computer goes into sleep mode, any chat program I am using is disconnected -- this happens with AIM, iChat, and Netscape Navigator's chat screen. As soon as I move my mouse, or touch the keyboard, and go active, AIM automatically reconnects. Any ideas on how I can remain signed into a chat service when I go into sleep mode?

In sleep mode your mac only keeps the data in the RAM. all other things will be turned off, so that it´s impossible to stay online with the chat applications.

Network chat program

I'm trying to make a chatting program for my home network, but I can't find one good tutorial on using java and networking. They all just show me how to make a server and client programs on my own machine. Big bunch a help that'll give me. Can someone help me?
I've searched everywhere.
Thanks!

Ah hell guys, if one of you is going to stand still and let the other run over, first, let me film it. Faces of Death needs a new movie! Second, let's use something better than a car for crying out loud! I'm thinking of a crane and ball, swing that sucker as fast as possible, or let's see if like in the cartoons, dropping a piano really does allow you to break through it, or if it would just flatten you. At least use a friggin' 18 wheeler or something so we can see body parts fly all over the place!

GUI for chat program

Hi everyone,
I'm writing a simple chat program as a assignment at my Uni. I get stucked with the client GUI. I want to create a GUI like that of Yahoo messenger which has a list of connected users displayed on the GUI. When u double click on the name of the user, u will get connected to that user. I have no idea about creating a GUI list like this one. Can anybody help me with this? Thanks in advance!

There are many tutorials on this site; check the "tutorials" link on the column on the left.
Here are ones about GUIs:
http://developer.java.sun.com/developer/onlineTraining/GUI/
I'd suggest skipping over any tutorials prior to JDK 1.1 or even 1.2.
Read more recent ones. There have been significant improvements, especially w.r.t. event handling, between 1.0 and 1.1.

Integrate A Chat Program with a Web Page

Integrate A Chat Program with a Web Page

I have an iPad 3rd generation and I get that message as well so it has nothing to do with having an iPad 2. The message means exact,y what it says, there was a problem loading the web site. In some situations, it just might be a problem with the website itself. Please note that I said in "some" situations. If you are getting this message every single time that you try to load a page, something is wrong.
Did you clear Safari, close all apps and then reset the iPad? Settings>Safari>Clear history and website data.
Now close all apps. In order to close apps, you have to drag the app up from the multitasking display. Double tap the home button and you will see apps lined up going left to right across the screen. Swipe to get to the app that you want to close and then swipe "up" on the app preview thumbnail to close it.
Next, reset the iPad by holding down on the sleep and home buttons at the same time for about 10-15 seconds until the Apple Logo appears - ignore the red slider if it appears on the screen - let go of the buttons. Let the iPad start up.

Is that possible ? (Chat Program)

I just found a great source code for a basic Server/Chat Program, but both works on a Frame... I want the Client to run on an Applet (Web Page) and the server to run on a PC in a Frame.
Is that possible... ? If yes, how do I do that? I can send the source code if you want.

Hi,
I am developing a socket server and client application for some other purpose than chatting. In my application, the Log Server is a Daemon Thread always be listening to the client requests. On listening to a request it spawns a RequestProcessor thread to process the requests.
The client is a session manager servlet. When the new HTTP request is taken by it, it has to write the status of the HTTP request into to the remote log files on the Log server. So at the beginning HTTP request, it has to write into the remote log file. And then process the request which may take a few seconds. At the HTTP request process, this has to write again into the remote log file on Log Server.
In my code now: The session manager will open a client socket to the server. At the beginning of the HTTP request, it will getOutputStream() of that socket and flushes the data to the OutputStream. Please note that it doent close that client socket. Then it does some processing. Then at the beginning of the HTTP request, it will re-use the same client socket and get the outputStream of that socket and flushes the data to the OutputStream.
If I do this, what I observed is unless i close the client socket, the data is not actually being written to the outputstream. The server side RequestProcessor thread is able to read the data from the sockets inputstream, only when the client socket is closed.
Please suggest me how to resolve this. So that when ever the data is flushed to the outputsteram, the server side RequestProcessor thread must be able to read that immediately.
Please let me know asap.
Thanks in advance
Murali

Online chat program

hey guys, im new to the whole networking thing, and this is my first attempt at using the internet. i am making a chat program, and having some troubles.

public class CHAT2 extends JFrame implements Runnable, ActionListener

 public final int PORT = 3677;

public void send(String e)

 while(c < e.length()) {
 buffer[c] = (byte) (e.charAt(c) );
 c++;
 try {
 ds.send(new DatagramPacket(buffer,c, InetAddress.getLocalHost(), PORT));
 }catch(IOException ec) {
public static void main(String args[])
 System.out.println(new Date().getDay());
 CHAT2 ch = new CHAT2();
 ch.setVisible(true);
}it works when i use it on my computer, but when trying to go across my network it does not. i have a feeling it traces back to this line
ds.send(new DatagramPacket(buffer,c, InetAddress.getLocalHost(), PORT));
any ideas on how to fix it?
(remember i am very new to networking, so dont expect me to know much....)

InetAddress.getLocalHost() gets your localhost ip. i.e. the ip of the computer you are running the program on which means you will send the package to the same computer. to send it to another computer enter the ip-address of it.
