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*/} It's not wrong not knowing, but it's wrong not wanting to know.

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
