Question regarding the caveat...

Posted by Hiran on November 21, 2001 at 4:02 AM

Is it possible to determine the status of a process once it's been executed using Runtime.exec()? Ex. if I start playing a sound file (sound.wav) using "start c:\sound.wav" as the command that is passed to Runtime.exec(), is there any way to check if the sound file is done playing, to be able to play another sound file? Checking to see if the process has finished doesn't work (I've tried it), cause once Runtime.exec() is called and the command is executed, the process finishes (from the JVM's point of view).
