How to suspend a thread which is in WaitSleepJoin state.

Sakharam,

I have seen this message before in my opinion.

With a lot of answers.

Sakharam,
What are you expecting Thead.Suspend to suspend?

The playing of the music? It cannot do this, as you using the
objAudioRecorde rPlayer object to control playing of the music, you don't
tell us what the objAudioRecorde rPlayer is, but I suspect it has its own
thread to play the music (you are using a thread to control a thread, to
control yet another thread, and you are one thread away from where you need
to be...)

Thread.Interrup t actually wakes up a thread, by causing a
ThreadInterrupt edException to be raised on that thread.

I would expect the objAudioRecorde rPlayer to have methods to suspend,
resume, and stop playback of the music. The trick is going to be is you need
to suspend both your thread & objAudioRecorde rPlayer, resume both
objAudioRecorde rPlayer & your thread, plus stop your thread &
objAudioRecorde rPlayer...

As the thread the Cor suggested, I would review other playback methods other
then objAudioRecorde rPlayer. Or preferable I would research
objAudioRecorde rPlayer to learn how to have it playback sounds without an
unneeded thread in my app, as I strongly suspect it already is doing all the
threading it needs via some ASYNC option.

As I stated in the other thread:

I would think (hope) what ever you are using to play sounds has a similar
asynchronous setting.

If I needed to use a thread in my app, then I would use the PlaySounds API
directly without having the objAudioRecorde rPlayer object in the way...

Hope this helps
Jay

Hi All,

In following example, while playing file, if thread goes in WaitSleepJoin
state, due to Thread.Sleep method.
Now I want to suspend thread by clicking on cmdSuspend button. I have
written following code, which doesn't suspend it.
Even I tried it by calling m_PlayThread.In terrupt() method which suspends
the thread but cannot resume it again by calling Resume method.

Any kind help will be appreciated.

Thanks and Regards
Sakharam Phapale
