Re: Threads

Tech-Archive recommends: Repair Windows Errors & Optimize Windows Performance

.... and the best way for me to detect what threads are hanging is to run application in Debug Mode (F5) and invoke a close event from your application. Wait for a moment and then break all threads by using Debug->Break All button. Now you can switch between threads in a Debug->Windows->Threads window and see what happened with each of them.

Sounds like you still have other threads running.

it doesnґt work.

I have this code in the sub main method:

Dim oHomeForm As HomeForm

Dim oMyClass1 As MyClass1

Dim oMyClass2 As MyClass2

Dim PosicionThread As OpenNETCF.Threading.ThreadEx

Dim RegistrarThread As OpenNETCF.Threading.ThreadEx

Try

oHomeForm = New HomeForm

oMyClass1 = New MyClass1

PosicionThread = New OpenNETCF.Threading.ThreadEx(AddressOf oMyClass1.ObtenerBLPosicion)

PosicionThread.Start()

RegistrarThread = New OpenNETCF.Threading.ThreadEx(AddressOf oMyClass1.RegistrarBLPosicion)

RegistrarThread.Start()

Application.Run(oHomeForm)

oHomeForm.Dispose()

oMyClass1.Exit = True

PosicionThread.Join()

RegistrarThread.Join()

oMyClass2= New MyClass2

oMyClass2.EliminarAcceso()

Catch ex As Exception

MsgBox(ex.Message, MsgBoxStyle.OKOnly & MsgBoxStyle.Critical)

Finally

Application.Exit()

End Try


ObtenerBLPosicion And RegistrarBLPosicion has more o less this code:



public class MyClass1

private shared _salir as Boolean

Public Property Salir as Boolean
Get
Set
end property

public sub method()

  do while true
      ......
          if _salir then
              exit sub
          end if
      .......
  loop

end sub

end class

When i call "Join" method, the main thread wait to exit the others, but when "main" method finish, the application not finish.

Sorry for my english. I hope you understand me.

When the user tries to close the form you need to set a static flag that the worker process reads on a regular basis, don't allow the end user to exit until the threads are terminated. One way you can manage this more easily is by using OpenNETCF.Threading class using the "Join" method.

See http://www.opennetcf.org

The problem is that user close all forms but application not end because there are 2 threads running. And then i can't execute again the same application until i reset the device.

It's bad practice to terminate a thread. You need to check some flag periodcially during your worker thread to determine whether the user want to end the process or not.

Cheers
