Question

I have the following code :

class SoundPlayback
{ 
        protected volatile bool _playing;
        public bool Playing {...}

        protected void Begin()
        {
            while (Playing && _sheet.TimeTick != 0)
            {
                _sheet.PlaySounds();
                Thread.Sleep(_sheet.TimeTick);
            }
            _playing = false;
        }
}

I have a thread calling Begin() with thread start, which works fine for the first time around, but when _playing is false and I want to resume the playback, I’m unable to.
Help would be appreciated.

Threads (any threads, not just .Net):

• Sleep: BAD

• Block-on-Event: GOOD

Take a look at “Synchronization Essentials” in this most excellent tutorial:

• http://www.albahari.com/threading/part2.aspx#_Synchronization

And change your loop to:

1) Call some other function do to the “work”

2) rely on some global “done” variable (instead of exiting when “TimeTick != 0”!!!!!)
