Public Delegate Sub UIUpdate(ByVal args() As Object
Public Class Invoke

Private _control As Contro
Private _uiUpdate As UIUpdat
Private _args() As Objec

Public Sub New(ByVal c As Control
' store the control that is to run the method on its threa
_control =
End Su

Public Sub Invoke(ByVal UIDelegate As UIUpdate,
ByVal ParamArray args() As Object
' called by the client and passed the delgate that
' points to the method to ru
' as well as the argument
_args = arg
_uiUpdate = UIDelegat
_control.Invoke(New EventHandler(AddressOf _invoke)
End Su

Private Sub _invoke(ByVal sender As Object, ByVal e As EventArgs
' this is now running on the same thread as the contro
' so freely call the delegat
_uiUpdate.Invoke(_args) // <== THIS LINE IS MY PROBLEMS ================

How did you declare Public Sub Invoke(ByVal UIDelegate As UIUpdate, ByVal
ParamArray args() As Object) in C#?
It should be:
public Invoke(UIUpdate UIDelegate, params object[] args)

I dont understand your answer.

I have a Error: "Invoke cannot be called directly on a delegate." on the
last row.

This class will be use to update the UI of a form in the Compact Framework
and pass it arguments.

Alex is saying that you can't. You can only call Invoke on methods that
exacly follow the EventHandler method signature. "Passing" data has to be
done using a global variable.

Hi Franky,

Check out this FAQ item:
