Look in the TOP RIGHT CORNER of *ANY* PAGE in these forums.

See where it says:
NEED TO DOWNLOAD CODE
View our list of code downloads
????

Okay, try CLICKING on that link.

That will take you to a page that says
Browse Titles for Code Downloads (511)

And you could just keep click on the next page, next page, next page until you get to your title.

But an easier way is to type the title into the SEARCH box, labeled Search titles for:

Type in "Professional Active Server Pages 3.0" and hit the GO button.

PRESTO! You get to a description of the book AND on that same page, there is a link that says Download Code

Now try clicking on *THAT* link.

PRESTO! All the code!!!

Incidentally, on the page that describes the book and has the direct download link, there is another link labelled "Errata". You might want to go there, too, to find errors that have been found in the books since it was published...9 years ago!
