Set selection mode from VB

The C# construct to set the selection mode to ‘Surface’ is:

SetSelectionMode(SelectionModes.Surface);

I am trying to achieve the same result in VB.net under Visual Studio, but have been unable to discover the correct syntax.
My project has references to ‘System.Drawing’ and ‘System.Windows.Forms’ and includes the lines:

Imports System.Drawing Imports System.Windows.Forms
Thanks,
Kevin

The problem was due to an error in my conversion of SetSelectionMode from C# to VB.net.

Here is the working VB.net code converted from the C# example in the API help:

' This method sets the selection level. Private Shared Sub SetSelectionMode(ByVal mode As SelectionModes) ' Go through all present windows. For Each w As Window In UIEnvironment.Windows ' If there is a DocumentWindow that contains a GraphicControl If (TypeOf w Is DocumentWindow) AndAlso (TypeOf w.Control Is GraphicControl) Then ' Set the SelectionMode. Dim gc As GraphicControl = TryCast(w.Control, GraphicControl) If gc IsNot Nothing Then gc.Picker.SelectionMode = mode End If End If Next End Sub
This sub is called using the same construct as in C#:

SetSelectionMode(SelectionModes.Surface)

This free on-line code converter did a better conversion than I managed:
