Hi all,

How can use BackgroundWorker or Threading for my code. I update TreeView (Winforms) and I call WCF service.

Any suggestions please. Kind regards.

Thanks in advance

AdministradorUILogging.TrazarDebug("PanelArbolFicheros. tslGuardarArbol_Click")

Dim listaFichero As New List(Of Fichero)

Windows.Forms.Cursor.Current = Cursors.WaitCursor

Me.TreeViewGB1.SuspendUpdate()

For Each nodo As NodoArbol In TreeViewGB1.Nodes

ProcesarNodo(nodo, listaFichero)

Next

Me.TreeViewGB1.ResumeUpdate()

' Cambiamos el cursor , tener en cuena si hacerlo asincrono

Try

Using bfll As New ComunBfll()

bfll.AltaManualListaFicheros(listaFichero)

Mensajes.InformacionGuardada()

End Using

Catch ex As WCF.ServicioBase.Contrato.Excepciones.NoExisteOperacionException

Mensajes.AdvertenciaErrores("No existe la operación")

Catch ex As WCF.ServicioBase.Contrato.Excepciones.NoExisteExpedienteException

Mensajes.AdvertenciaErrores("No existe el expediente")

Catch ex As WCF.ServicioBase.Contrato.Excepciones.ConsistenciaException

Mensajes.AdvertenciaErrores("Inconsistencia detectada al superar el máximo permitido de ficheros para un tipo documental")

Catch ex As Exception

AdministradorUILogging.TrazarError(Me.[GetType]().FullName & " -> " & System.Reflection.MethodBase.GetCurrentMethod().Name & "." & ex.Message)

ExcepcionesIUUtil.ProcesarExcepcionPresentacion(ex, Me.Container)

End Try

InicializarArbol()

Windows.Forms.Cursor.Current = Cursors.Arrow

Your code is very hard to read, I'd recommend posting here. Other than that, you already know the BackgroundWorker and Thread keywords. Yes, that's what you'll need. And Control.Invoke() to update the TreeView.

Hi,

You can clickhere to get more information about Control.Invoke, and there are many good samples. Besides, if you have questions about WCF Service, it’s likely to get quicker and better responses at Windows Communication Foundation.

Best regards,
