EnsureVisible in TreeView: how to ensure that horiz. scrollbar is aligned left

Question

Hi,
I have a tree view with eg. following nodes
# People
|
+--# Custumers
|
+-- # Anne Charles, Hillroad 14, 7766 MyTown, My Country
|
+-- # Steve Jones, Forestroad 12, 7766 MyTown, My Country
With the command
Me.treeViewM.Nodes(0).Nodes(0).Nodes(0).EnsureVisible()
I can ensure that "Anne Charles" is visible within the treeview. My problem is: If the treeview is not wide enough to show the complete node text of this node, the horizontal scroll bar is automatically moved to the right so that node structure shown left from the "A" in the text "Anne Charles" is not visible any more. Thus
Anne Charles, Hillroad 14, 7766 MyTown, My Country
Steve Jones, Forestroad 12, 7766 MyTown, My Country
is visible and the node structure is hidden.
Question: How can I ensure that the node "Anne Charles" is visible and also the horizontal scrollbar is aligned to the left, which means that the node structure left from the text is still visible?
Best wishes

Look at following code project also: http://www.codeproject.com/KB/tree/NoScrollingTree.aspx
You need PInvoke.
At Top
Imports System.Runtime.InteropServices
And Following Functtion 
    Private Const WM_HSCROLL As Integer = 276
    Private Const SB_LEFT As Integer = 6
    <DllImport("user32.dll")> _
    Private Shared Function SendMessage(ByVal hWnd As IntPtr, ByVal wMsg As Integer, ByVal wParam As Integer, ByVal lParam As Integer) As Integer
    End Function
After Ensure Visible call the above Function
    Me.treeViewM.Nodes(0).Nodes(0).Nodes(0).EnsureVisible()
        SendMessage(treeViewM.Handle, WM_HSCROLL, SB_LEFT, 0)
