Hi Noel,

is there any literature that gives a good overview of the
api - I'd like to become familiar with it but the on-line documentation on
the msn website is a bit daunting!

Just a FWIW, but we have a chapter called "Understanding and using the
Windows API" in our new book "Professional Excel Development", due out in
February. That chapter had some very favourable reviews from our editors.
