How to suspend a thread which is in WaitSleepJoin state.

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
