Hi all,

I have a problem regarding  use of manualreset events in .net.
I have a developed a sample appliation in which entries from the
listview which I say is a queue for my processes.I want to schedule
these processes in my queue.
   I also want to stop the processing by selcting the pause so that the
scheduling stops and again if i say add schedule the schedule should
start again.I have used manual reset events to control the
communication between  scheduling. Bcz msdn  says we can't have control
on autoreset events.
Remember I have used only one thread which is managing the entire
processing.

The sample code which i have tried is -

Class transferManager

  Public  Function New()
         transferEvent(transferEvent.DATAAVAIL) = New
ManauaResetvent(false)
         transferEvent(transferEvent.STOP) = New ManauaResetvent(false)
'pause the transfer
         transferEvent(transferEvent.TERMINATE) = New
ManauaResetvent(false)
End Function

Public Function Start(Byval lvw as listview)
  tranfermanager = lvw
   transferThread.start()
End Function


Public Function Stop()
'check for wheter set event is data avail if yes then
  transferEvent(transferEvent.DATAAVAIL).reset()
  transferEvent(transferEvent.STOP).set()
'else
  transferEvent(transferEvent.STOP).set()
End Function


Public Function DataAvailable()
'check for wheter set event is stop if yes then
  transferEvent(transferEvent.STOP).reset()
  transferEvent(transferEvent.DATAAVAIL).set()
'else
  transferEvent(transferEvent.DATAAVAIL).set()
End Function


Public Function TransferEngine()  'thread proc associated with the
thread
   Do while
     'if any of the stop or terminate set then return
     Do while   tranfermanager.items.count <> 0
                  transfer(  tranfermanager.items(0)) 'start process
     end while
  end while

End Function

Private transferEvent(2) as ManualResetEvent()
Private transferThread as new thread(false)
Private  tranfermanager as new listview

End Class

SO my exact problem is i say "add schedule"  the process is added and
call to  DataAvailable() is given so that the scheduling is started .
But in between if i say stop the schudule is stoopped by calling
Stop(). Now if i again say add shedule call to DataAvailable()
doesn't start the thread again it is in 'stopped' state what could be
the reason. Any ideas.
That means somehow my Threadproc is not executing again after pause
Sample application would also do.

Thanks in advance
