Help on total vb sourceBook

Hi guys,
I am looking for a programming assistant for Microsoft
office that offers me code samples to common problems in MS office with code
that is easy to understand and modify with good error handling support. I
understand that total visual sourcebook is the best software for this, what I
would like to know is where I can purchase total VB
sourcebook.
If anyone can help me on this please reply to this post.
