I can't seem to get back to the Errata page for this book that says to delete InitializeComponent(), that it was autogenerated by a pre-release version of VS.NET, but...
Can anyone confirm that this entire sub and all calls to it should be deleted from all .aspx.vb code-behind files?
Thanks.

I'm not sure of the context where "InitializeComponents" was to be removed, but ordinarily you would not remove it.

The code, as shown below, appears to be in every .aspx.vb code-behind for every module except the 'FileManager' module. So this is a pretty broad reaching change.
Why do you say 'ordinarily you would not remove it'? Have you dealt with this issue before?
It's strange, if I comment out the call to InitializeComponent() in OnInit, then OnInit doesn't even get called. Why would that be?

    Protected Overrides Sub OnInit(ByVal e As EventArgs)
      MyBase.OnInit(e)
      InitializeComponent()
    End Sub


    'This call is required by the Web Form Designer.
    <System.Diagnostics.DebuggerStepThrough()> _
    Private Sub InitializeComponent()
      AddHandler Me.Load, AddressOf Page_Load
    End Sub
