      You need to marshal the call back to the GUI thread using
      'control.begini nvoke"

              Private Delegate Sub UpdateControlDe legate(ByVal Text as string)

              Private Sub UpdateControl(B yval Text as String)
              If MyControl.Invok eRequired Then
              MyControl.Begin Invoke(New UpdateControlDe legate(AddressO f
              UpdateControl), new object(){Text})
              Else
              ... Do Update Here
              End If
              End Sub


              P.S. you don't need to create the delegate if you're not passing in
              parameters - in which case you can just use the built in MethodInvoker
              delegate.
