Hi Experts,


A simple question...

I have developed an application and from that application I have to start another application that is on my hard disk.
Is there a way to start that outside application from my application.



Thanks

I get the following messasge when I run the code :

java.lang.IllegalThreadStateException: process has not exited
      at java.lang.ProcessImpl.exitValue(Native Method)
      at alarms.Test.main(Test.java:13)


I have to say that when I  excecute EzDownloader,  another message box appears and ask me to push on the button Download now.

I forgot to include my code :

import java.util.*;
import java.io.*;


public class Test
{
    public static void main(String args[])
    {
        try
        {            
            Runtime rt = Runtime.getRuntime();
            Process proc = rt.exec("F:/ua/EzDownloader");
            int exitVal = proc.exitValue();
            System.out.println("Process exitValue: " + exitVal);
        } catch (Throwable t)
          {
            t.printStackTrace();
          }
    }
}

exitValue() throws IllegalThreadStateException - if the subprocess represented by this Process object has not yet terminated.

You can use waitFor to wait for the process to terminate
