Changing Style of Common Control Toolbar

I would like to change the style of the Common Control Toolbar to support the new Flatbar style...  I have implemented the following code in the Form Activate event but it does not appear to work...

Dim lStyle As Long
Const TBSTYLE_FLAT = &H800
lStyle = GetWindowLong(tbrStandard.hWnd, 0)
lStyle = lStyle Or TBSTYLE_FLAT
SetWindowLong tbrStandard.hWnd, 0, lStyle

This code was taken from the CWnd::ModifyStyle code in the MFC class libraries...

1) Does the Common Control Support this style
2) Is this code valid or do I need to do something else

use this code and you will be able to make a flat toolbar
Declare Function SendMessage Lib "user32" Alias "SendMessageA" (ByVal hWnd as Long, ByVal wMsg As Long, ByVal wParam As Integer, ByVal lParam As Any) As Long
Declare Function FindWindowEx Lib "user32" Alias "FindWindowExA" (ByVal hWnd1 As Long, ByVal hWnd2 As Long, ByVal lpsz1 As String, ByVal lpsz2 As String) As Long

Global Const WM_USER = &H400

'Toolbar Messages
Global Const TBN_FIRST = &H700&
Global Const TB_SETSTYLE = WM_USER + 56
Global Const TB_GETSTYLE = WM_USER + 57

'Toolbar styles
Global Const TBSTYLE_FLAT = &H800

Sub SetToolbarFlat(tlbTemp As Toolbar)

Dim Style As Long, lngResult As Long, lngHWND As Long

   'Gets the *real* toolbar (it is inside this one)
   lngHWND = FindWindowEx(tlbTemp.hWnd, 0&, "ToolbarWindow32", vbNullString)
   'Gets old style
   Style = SendMessage(lngHWND, TB_GETSTYLE, 0&, 0&)
   'Adds new style
   Style = Style Or TBSTYLE_FLAT '
   'Modifies the style
   lngResult = SendMessage(lngHWND, TB_SETSTYLE, 0, Style)
   tlbTemp.Refresh

End Sub

'Now you can put call the function on a form load event for the 'form that contains the toolbar, as in:

Sub Form1_Load
SetToolbarFlat Toolbar1
End Sub

I have...  All the code works (in that it runs/compiles without producing errors) however it does not appear to do anything.

i've a small revision to this code, in GetWindowLong and SetWindowLong where it is a 0 it should be -16. -16 is the index for the style. However this doesn't do a thing in VB. Does it really works in Visual C???

In Visual C I used the ModifyStyle command... This produced a Flat toolbar, however this was using the CToolbar functionality, which should be using the Common Control DLL but may not do I suppose...  I will look into it further and find out.

I added this code to the project... Whilst it works, there would appear to be some problems.

1) The control does not work correctly. i.e. the buttons to not highlight when you move over them.

2) On the MDI Form the code does not work. Any more suggestions.
