Windows Media Player no sound while playing a avi file in server and client connection using TCP/IP connection

Hello there
I have a problem with my windows media player while using server and client connection by using TCP/IP connection. So when I play a video using Windows Media Player in LabVIew there isn't any sound come out but when I'm playing a video by a Windows Media Player only the sound will come out. Can you help me solve this problem?
I also upload the vi as the reference.
The username for the client is ihsanhaikalz and the password is ganteng
Thanks

Hi ican,
I was looking at your VI's but I cannot seem to pinpoint exactly where you are using Windows Media Player. In order to more quickly assist you, could you please recreate this issue more concisely in a smaller set of VIs. Also, were you able to get sound when you did not use the TCP/IP connection and simply played the files in LabVIEW?
I noticed in a few places that you were using the Play Sound File.VI from the Graphics and Sounds palette. Is that what you are refering to? I noticed there that the file path that you have designated for the song is simply the song title. Instead, this should be a path to where the song is located on your computer.
Also, if you are planning on using Windows Media Player, have you considered using the ActiveX commands for Windows Media Player? Here are a few examples if you are unfamiliar with this functionality.
Example 1 and Example 2.
I hope this helps!

Try to use one comupter as both server and client

Hello, everyone, I am just trying to use my own computer as both server and client to test some codes about networking. For example, use the sample code in java tutorial which is used to test Echo server(code is listed below). Is there anything I have to do to set my computer, such as set my hostname or something like that?
I am a pure newbie. And the purpose of this question is to test some code including socket on one PC without connect to internet.
I have tried to change the name "taranis" in the following code to the computer name of my own PC, but it doesn't work, and said: Couldn't get I/O for the connection to: (my computer name).
import java.io.*;
import java.net.*;
public class EchoClient {
public static void main(String[] args) throws IOException {
Socket echoSocket = null;
PrintWriter out = null;
BufferedReader in = null;
try {
echoSocket = new Socket("taranis", 7);
out = new PrintWriter(echoSocket.getOutputStream(), true);
in = new BufferedReader(new InputStreamReader(
echoSocket.getInputStream()));
} catch (UnknownHostException e) {
System.err.println("Don't know about host: taranis.");
System.exit(1);
} catch (IOException e) {
System.err.println("Couldn't get I/O for "
+ "the connection to: taranis.");
System.exit(1);
     BufferedReader stdIn = new BufferedReader(
new InputStreamReader(System.in));
     String userInput;
     while ((userInput = stdIn.readLine()) != null) {
     out.println(userInput);
     System.out.println("echo: " + in.readLine());
     out.close();
     in.close();
     stdIn.close();
     echoSocket.close();

Did you write the EchoServer and start it on your
machine, listening on port 7?
You can have the client and server running on the same
machine or different machines, but they have to be
separate pieces of software.
Write a separate EchoServer class that starts up and
listens on that port. Then start the EchoClient and
make the connection.
%yeah, I didn't wrote the EchoServer class. But I thought it is automaticly included and therefore has run once I start my computer.
If I write a EchoServer class, then how should I set the host name of the EchoClient, just simply change "taranis" to my computer name (change "echoSocket = new Socket("taranis", 7);" to echoSocket = new Socket("(my comptuer name)", 7);"?

I am using server and client systems when i am trying to open the browser in two or more machines it says that firefox is already running, i want to open the browser in all machines simeltaniously

I am using server and clients machines in my office, here i want to open browsers in all systems simultaneously but i am unable open the browser, when i am trying to open the browser in the second machine it says that firefox is already open... pls. solve this problem
Thank you

You can't open one Profile more than once. You need a separate Profile for each browser on each PC that you open.

Data streaming between server and client does not complete

Using an ad-hoc app, data streaming between server
and client does not complete as it supposed to be.
The process runs well in solaris 5.8, however under 5.9
we have found the characters stream buffer length limitation
is around 900 to 950 characters (by default we are using 3072
characters).
Example:
- We are transfering HTML file, which will be displayed
in the App client, with buffer=3072, the HTML only displayed / transfered
as xxxxxxxx characters, but with buffer=900 the HTML is displayed properly,
in this case, the only problem that we have is the file transfer will
eventually longer than usual.
- There is another case, where we have to transfer information (data) as stream
to the client. A long data stream will not appear at all in the client.
Any ideas why the change between 5.8 and 5.9 woudl cause problems?
The current app-driver that we are using is compiled using Solaris 5.6,
if possible we would like to have use of a later version, which is compiled using Solaris 5.9, do you think this will probably solve our problem?
Thanks
Paul

Does this have anything to do with Java RMI? or with Java come to think of it?

Can I put both RMI server and client in a same program

hi everybody...
I wanna know that can I use RMI server and client in a same program....My idea is like that I wanna use the same program for client and server....When I open my program, I can accept connection from other program and if I want to connect to others, I can also connect it. I expect you to understand my question. Here are the sample code for my program...
package Chat.Rmi;
import java.lang.*;
import java.util.*;
import java.rmi.*;
import javax.swing.*;
import java.net.*;
import java.rmi.server.*;
import java.rmi.registry.*;
public class netKitManager implements netKitInterface{
    public netKitManager(){
        try{
        reg = LocateRegistry.createRegistry(4242);
        reg.rebind("NetKitServer",this);
        }catch(RemoteException re){
    public void DirectConnect(String ip){
        try{
        netUser = (netKitInterface) Naming.lookup("rmi://"+ip+":4242/NetKitServer");
        JOptionPane.showMessageDialog(null,"Connection succeded!");
        }catch(NotBoundException nbe){
            JOptionPane.showMessageDialog(null,"There is no server at specified IP address!");
        }catch(MalformedURLException mue){
            JOptionPane.showMessageDialog(null,"IP adress may be wrong!");
        }catch(RemoteException re){
            JOptionPane.showMessageDialog(null,"Remote exception occured!");
    public void SendMessage(String msg){
        try{
        netUser.SetMessage(msg);
        }catch(RemoteException re){
    public void SetMessage(String msg) throws RemoteException{
        chatKit.SetMessage(msg);
    private netKitInterface netUser;
    private Hashtable netUserList;
    private Registry reg;
}

Yes it can be done. I have done it.

UDP server and client running on same machine

Hi all,
I can't get the QuoteServer example to work. I am trying to run both server and client on same machine since I only have one machin available at the moment.
I am using win xp behind a firewall. Anything that might interfere?
With some System outs I can see that the server is waiting for request but never getting any...

Restarted computer and now it works. Are ports locked up if I get an exception in the 'wrong' place?

Problems with games server and client

Hi! I am making an MMORPG game and I have problems with the server and client connection.
I can connect to the server, but when a second player does, the server console tells me this:
java.net.SocketException: Connection reset
After that, all clients disconnect.
Which is the problem?
How can I solve it?
Thank you so much

Here is how my sever work. I took some of this code from a book called Killer Programming Games in Java. If you google for it, you will find it for sure.
TourGroup tg = new TourGroup(); // this object stores information about all clients connected to the server
    try {
      ServerSocket serverSock = new ServerSocket(PORT);
      Socket clientSock;
      while (true) {
        System.out.println("Waiting for a client...");
        clientSock = serverSock.accept();
        new TourServerHandler(clientSock, tg).start(); // this is the thread that monitors each client
    catch(Exception e)
    { System.out.println(e); }
} This is some code of TourServerHandler
public TourServerHandler(Socket s, TourGroup tg)
    this.tg = tg;
    clientSock = s;
    name= "?";
    cliAddr = clientSock.getInetAddress().getHostAddress();
    port = clientSock.getPort();
    System.out.println("Client connection from (" +
                 cliAddr + ", " + port + ")");
public void run()
// process messages from the client
    try {
      // Get I/O streams from the socket
      BufferedReader in = new BufferedReader(
   new InputStreamReader( clientSock.getInputStream() ) );
      PrintWriter out =
new PrintWriter( clientSock.getOutputStream(), true );
// and here goes the rest... The TourServerHandler thread uses this code to send messages:
tg.broadcast(msg); tg.broadcast works like this:
synchronized public void broadcast(String cliAddr, int port, String msg)
// broadcast to everyone but original msg sender
    TouristInfo c; // this object stores info about the client
    for(int i=0; i < tourPeople.size(); i++) {
      c = (TouristInfo) tourPeople.get(i);
        c.sendMessage(msg);
} This is the error part
public void sendMessage(String msg)
PrintWriter out;
    out.println(msg);
      System.out.println("OK");
} I can't find any error but I still get that Connection reset exception...

Differences between GKAPI server and client modes

Cisco Gatekeeper External Interface Reference does not talk much about the server and client modes. Does anyone know the different between these 2 modes?

Hi Krishna,
Have a look at the two links below. They provide configuration examples for each of the two topologies along with explanation on the different commands used.

Force CORBA server and client to localhost

Hi,
i have to run an omg corba server and client via orbd on a single machine with win xp. The machine is connected to the network, but this is not relevant for the corba communication.
I can now force the orbd to start at localhost. After starting server and client everything works well until disconnecting machine from network, because client and server are started at ip of network card.
How can i force the client and server to use a localhost port for corba communication (client and server)?
Hope anyone has an idea...
br
ralf
P.S.: If I start the applications after disconnecting network everthing works.

Resolved the problem myself.
The correct property is a java system property:
com.sun.CORBA.ORBServerHost=localhost
If you set this property in your application before instanciating an ORB, the orb will be forced to run on the set value (in this case localhost). If you do not set this property the ORB will be started at the IP of your network card if it is active (connected to the network)...

Connection fails if server and clients are in different subnets

Hello,
our Volume License Manager (v2.1) is running in another subnets than the clients (All machines are running under Windows XP-SP2 without Domains or ADS, just workgroups).
The server is in subnet A (192.168.42.0/24), all clients are located in another subnet B (192.168.50.0/24).
Routing is properly configured and is working fine, traffic to the specific hosts is not blocked by a firewall. We can ping every machine,
open telnet connections to the NILM, everything works.
But if the clients try to connect to the remote NILM (both local client NI License Manager and VLM port settings are correct) their connection attempt always
times out with error code "NILM10"
(I already read the mentioned KBs, no solution has helped so far). This is true if clients and server are separated.
For testing purposes, i plugged one client into the server's subnet (server's IP: 192.168.50.250, client 192.168.50.10)
and it worked perfectly. Is there a reason why server and client have to be on the same subnet or is it some other kind of problem that I am not aware of?
Thank you.
Thorsten

Hello Thorsten,
Did you add the server's domain to the client computer's DNS settings. To do this, complete the following steps on the client computer:
1. Open Local Area Network Settings from the Control Panel (Start»Control Panel»Network Connections»Local Area Connection)
2. Click the Properties button
3. Select Internet Protocol (TCP/IP) from the list of network components
4. Click the Properties button
5. Click the Advanced button
6. Change to the DNS tab
7. Ensure Append these DNS suffixes is selected
8. Click the Add button
9. Enter the domain suffix of the license server and click Add
10. Close any open dialog boxes, choosing OK and Close as necessary.

Time sync between server and client

Hi guys,
I have written a chess server and client. My next step is to implement a clock which will be used in timed games, however, I am not sure of the best solution. I can't think of a reliable method to keep the client's time in sync with the servers because the event latency varies between individual events and clients.
My first idea was to send a 'tick' event every second but I dont think this the best solution. I have seen many applet based clients which have timers, such as Yahoo chess.
I know this question is a little vague, I can give more detail if needed.
Thanks,
Alex

To prevent client-side cheating, the server should keep the
"official" clock. Every so often (perhaps when a move gets made?),
notify both clients of the official time. Clients count seconds from
that official time.
This is a suboptimal solution because it leaves clients vulnerable
to network lag. I can't think of any other solution that doesn't give
clients some responsibility for tracking time, though, and that's a
big security hole.
If you're willing to open that hole, have each client report back to
the server the elapsed local time from when they recieved the
last move to when they made their move. Then update the other
client's clock accordingly.

Redundant folders created in root of C drive of server and Client . I want to stop the same and want to automatically delete them from server and client .

Redundant folders created in root of C drive of server and Client . I want to stop the same and want to automatically delete them from server and client .
Please let me know the solution to delete them not manually . It should not create automatically .Is there a way we can change the path of creation.
Is there a way that once the folfer is create should be automatically deleted once the task is done.
Redundant folders are created in the root of my C drive all the time,
folder names look like:
