Updating controls on a form

Unless my app is EXTREMELY simple, I get the cross-threading error message
regularly when updating controls on a Windows form.

My latest example involves a dll that runs a System.Threading.Timer,
updating private shared variables.  When it finishes updating, it raises a
NewData event.  My app responds to that event by updating display controls
(labels in this case).  I have to use a delegate and update them like this:

Private Sub SetText(ByVal [text] as String)
    If Me.Messages.InvokeRequired Then
        Dim d as New SetTextCallBack(AddressOf SetText)
        Me.Invoke(d, New Object() {[text]})
    Else
        Me.Messages.Text = [text]
    End If
End Sub

I have to write a different routine like this for each control on the form
that I want to update.  Is there a better way?  Please?
