Thanks for the reply,
I downloaded the Icons because they were not included in the Visual Studio program download. I did not use the downloaded code from the book suppliers.
I wrote it as it is in the book, I only changed the path where the icons are:
/<Button Name="tbrHelpAbout" ToolTip="About">
<Image Source="file:///C:/Visual Basic internet programs/VS2012 Modern Image Library/Actions/bmp/Help_6522_32></Image>/
The others are the same.
Is there something I'm doing wrong?
