cross-thread UI updating?

i found this informative MSDN article:  

    http://msdn.microsoft.com/msdnmag/issues/03/02/Multithreading/

...which shed some serious light. using it, heres what i came up with:



    Private m_data As MyData

    ...

    Private Sub LoadForm()

        'a built-in delegate for calling paramter-less methods (wont work if FillMyData()
        'takes an argument, use different one or write one)

        Dim mi As MethodInvoker = New MethodInvoker(AddressOf FillMyData)
        mi.BeginInvoke(Nothing, Nothing)

    End Sub


    Private Sub FillMyData()

        'get data
        m_data = FillFromWebService()
        
        Dim eventArgs() As Object = {Me, System.EventArgs.Empty}

        'update UI's label
        statusLabel.BeginInvoke(New System.EventHandler(UpdateUI), eventArgs)     'this is from MSDN article. but wont compile!?

        'update UI's visual control
        myControl.BeginInvoke(New System.EventHandler(BindUIData), eventArgs)     'this is from MSDN article. but wont compile!?

    End Sub


    Private Sub UpdateUI(ByVal sender As Object, ByVal e As System.EventArgs)
        'this method is called via Control.Invoke, so its allowed to touch UI
        statusLabel.Text = "done!!"
    End Sub


    Private Sub BindUIData(ByVal sender As Object, ByVal e As System.EventArgs)
        'this method is called via Control.Invoke, so its allowed to touch UI
        myControl.BindData(m_data)
    End Sub



this sample uses "Asynhronous Delegate Invocation" for its threading. it uses it once to spawn the worker-thread, and from inside that it uses it twice more to tap back into the UI-thread (a label update, and a databind). only problem? the work-process' attempt to use ADI doesnt compile. says:

"'System.EventHandler' is a delegate type. Delegate construction permits only a single AddressOf expression as an argument list. Often an AddressOf expression can be used instead of a delegate construction."

...i tried using AddressOf, and that failed as well:

"'AddressOf' expression cannot be converted to 'System.Delegate' because 'System.Delegate' is not a delegate type."


 hmm... so close! anyone help a brother out?


thanks,
