I am probably just talking to myself, but I found that while Session ending does not work. The following work around does:
'-----------------
Public Sub WindowsClosing(ByVal sender As Object, ByVal e As System.ComponentModel.CancelEventArgs)
Dim x = CType(sender, Window)
If Me.Windows.Count = 1 Then
e.Cancel = MsgBox("Do you wish to close the last window and exit the program?", MsgBoxStyle.YesNo) = MsgBoxResult.No
End If
End Sub
'---------------
It checks if this is the last window for the application. Since the application has Shutdownmode=OnLastWindowClose{0} this works by allowing the user to cancel the las windows closing.

I am a little surprised that there is no one in this discussion. Hopefully my question will be answered.

I just bought the book, and started on chapter 1. I also downloaded the Zip files with the vb equivalents of Petzold's book, thank you for the help.

1. Protected Overrides Sub OnSessionEnding(ByVal e As System.Windows.SessionEndingCancelEventArgs) never stops in the vb version of InheritTheApp.cs

I added a close windows intercept "Sub CloseWindow(ByVal sender As Object, ByVal e As System.ComponentModel.CancelEventArgs) Handles win.Closing" which does intercept. Unfortunately the session ends anyway closing the window even though I canceled.
Any ideas?

2. If you use the normal Create WPF project, you must delete Application.xaml and Windows1.xaml or the code in Petzold will not work as provided. Furthermore, if you are using "STRICT" you need to fix the lack of a cast in MyWPFExtension from cType(Global.System.Windows.Application.Current,Application)
What is happening here?
Puzzled,
Leon

Charles Petzold's latest book, Applications = Code + Markup: A Guide to the Microsoft Windows Presentation Foundation, is the best WPF book available right now. Unfortuantely, all code samples in the book are written in C#. In order to help VB developers trying to learn about WPF, we are working with a couple of VB experts to convert all samples appearing in the book to VB. As we finish converting each chapter, this page will be updated with a link to sample code package.

Quick info about two experts helping us with this.

- Evan Lim is currently teaching WPF & Blend courses at Foothill Community College in Los Altos, CA.

- Ged Mead, VB MVP, is currently based in an idyllic lochside location in the West of Scotland and is currently involved in an ever-widening range of VB.NET development projects, which include research for a proposed .NET book as well as writing articles, organising and creating online courses in .NET technologies.
