Need help with Addin presentation from SW World 2007 - Or Addinstutorials in general

I'm reviewing a SW World 2007 presentation I attended titled
"SolidWorks Addins Using .NET".

The steps are:

1. Record a simple macro in SolidWorks using VBA.
2. Verify the macro.
3. Start Visual Studio.
4. Create a new SW Addin using SWVBAddin Template.
5. Open SwAddin.vb
6. Expand the code region.
7. Select all of the code in 'Sub CreateCube ()'
8. Use Ctrl+K C to comment out the code
9. Swith back to VBA and select all the code in 'Sub main ()'
10. Copy and paste back to Visual Studio.
11. Add 'Dim' statements for each object.
12. Replace 'Applications.SldWorks' with 'GetObject
(,"SldWorks.Application")'
13. Build the Addin and Run using F5 to debug SolidWorks.

I followed all of the steps, but nothing happens in SolidWorks. The
macro works fine if I run it thru VBA.

Any ideas? If anyone knows a good tutorial for creating SW Addins
with VB.NET, please post.

Below is the code under 'UI Callbacks'


#Region "UI Callbacks"

Sub main()
Dim swApp As Object
Dim Part As Object
Dim SelMgr As Object
Dim boolstatus As Boolean
Dim longstatus As Long, longwarnings As Long
Dim Feature As Object
swApp = GetObject(, "SldWorks.Application")

Part = SwApp.ActiveDoc
SelMgr = Part.SelectionManager
boolstatus = Part.SetUserPreferenceToggle(196, True)
boolstatus = Part.Extension.SelectByID2("Unknown", "BROWSERITEM", 0,
0, 0, False, 0, Nothing, 0)
boolstatus = Part.Extension.SelectByID2("Front", "PLANE", 0, 0, 0,
False, 0, Nothing, 0)
Part.SketchManager.InsertSketch(True)
Part.ClearSelection2(True)
Part.SketchRectangle(-0.08407285067873, 0.06711078431373, 0,
0.06953393665158, -0.05404683257919, 0, 1)
Part.SetLineWidth(4)
Part.SetLineWidth(4)
Part.SetLineWidth(4)
Part.SetLineWidth(4)
Part.SetPickMode()
Part.ClearSelection2(True)
Part.SketchManager.InsertSketch(True)
Part.ClearSelection2(True)
End Sub
