the code goes like this:

try
{
 Runtime rt = Rintime.getRuntime() ;
 Process p = rt.exec("Program.exe") ;
 InputStream in = p.getInputStream() ;
 OutputStream out = p.getOutputStream ();
 InputSream err = p,getErrorStram() ;
 
//do whatever you want
 //some more code
 
 p.destroy() ;
}catch(Exception exc){/*handle exception*/}

try out this code ... it will not be platform independent ....
Process p = Runtime.getRuntime().exec("c:\myprogram.exe");

I dont have the time to test it .... if you succeed please tell me too.
:eek:

i'm using the code from above to try to run a program and here's my problem... when i call an exe that i wrote in VB, the program runs fine. if i call a c or c++ program the program loads into memory (i see it in the processes tab) but the console doesn't open up with the program in it.
here's the code i have right now for it...

try
   {
    Runtime rt = Runtime.getRuntime();
    Process p = rt.exec("vbex.exe");
    InputStream in = p.getInputStream();
    OutputStream out = p.getOutputStream();
    InputStream err = p.getErrorStream();

    p.destroy() ;
    }catch(Exception exc){/*handle exception*/}

hi everyone,

              Do this instead



void run ()
{
try
{
Runtime rt = Runtime.getRuntime();
Process p = rt.exec("vbex.exe");
}

catch(Exception e)
{

}

}

I hope this helps you

Hi,

The following example shows opening a notepad using java application.

There are a load of answers in this 2004 zombie thread using Runtime.exec to run an external process, but this was superseded in Java 5 (JDK 1.5) with ProcessBuilder, which is now preferred to Runtime.exec

first of all, you could have figured out that this thread is 8 years old, and has been revived way to many times already. secondly, you could 've read the answers already given.

also, you might want to provide some more information.
are we talking a complete separate system? do you have a "client" app on the remote machine, can you access the remote machine, ... ?

[manish.mehta]

Yes, i saw that, but i thought my problem is something similar to it. hence i posted here.

Actually, i am using Selenium Grid and running my test cases on remote machine. And i am also using Screen recorder to record video for my test. When i start Screen recorder, it only starts in the hub machine (my machine). So i thought to run the Screen recorder on remote machine by running a batch file using my Selenium Java code.
