Finding us in bookstores

Naturally, we'd like you to buy online, direct from us. (It's part of our dastardly plan for domination of the solar system. Our authors and us also make more money when we don't have to split the funds with dozens of middlemen.)

However, we realize that some people like browsing through bookstores. (We've been known to do that ourselves, albeit with dark glasses and a trenchcoat.) If you're one of those folks, we encourage you to "buy where you browse." It's unfair to take advantage of a bookstore's facilities to look through books and then order online just to save a couple of bucks.

So, conveniently for you bookstore-goers, our books are available in bookstores nationwide. We ship to all of the major chains (Barnes & Noble, Borders, Books-A-Million, Indigo) as well as wonderful specialty technical bookstores like the following:

Computer Book Works, 78 Reade Street, NYC
Digital Guru, 546-3 Lawrence Expwy, Sunnyvale CA
Op-Amp Technical Books, 1033 N Sycamore Ave, Los Angeles CA
Powell's Technical Books, 1645 NW Hoyt St, Portland OR
Quantum Books, 4 Cambridge Center, Cambridge MA
Reiters Scientific & Technical Books, 2021 K Street NW, Washington DC
San Diego Technical Books, 4240 Kearney Mesa Rd, San Diego CA
SoftPro Books, 75 Third Ave, Waltham MA
SoftPro Books, 6862 S Yosemite St , Centennial CO
Stacey's Bookstore, 581 Market St, San Francisco, CA

That said, we can't guarantee that they're going to be in stock in a particular bookstore on the day you walk into it. Why not? you wail. For the same reason that you might not find a quarter of Haagen-Daaz Chocolate-Chocolate Chip at Bob's Stop 'n Go on Route 41 in Terre Haute. Sometimes they just run out! We ship via intermediaries who are responsible for keeping individual stores stocked, and if there's a rush on a particular item, the natural lag time between the time the last widget goes out the door and the store orders more means that they might be out of stock for a bit. The good news is that the specialty stores will all special order for you as part of their normal course of business. The bad news is that, occasionally, an undermotivated clerk at a chain store will tell you tall tales (like "This book is out of print." when you know it was just published three months ago.) in order to avoid the hassle of special ordering it for you. (Hey, whaddaya expect for $8.00 an hour?)

Which book is right for you?

Which book should I buy? We've got over billyuns and billyuns of books. Well, dozens and dozens, actually - sometimes it's difficult to know which book most closely meets your needs. Here are some common scenarios and a suggested list of books.

Moving to Linux

Our Linux books are each customized for a specific type of function - Linux on the desktop, Linux as a file server, Linux as a Web server, and so on. As a result, there isn't a 'path' like there is for learning Visual FoxPro. However, if you're interested in a migration path to Linux for your home or office, I've got some suggestions here. In those suggestions, I also point you toward the book or books (as well as free whitepapers and other resources) that might be useful in your quest.

Starting out with VFP

If you're new to FoxPro in general or experienced with FoxPro 1.x, 2.x or another xBase dialect, and want to learn Visual FoxPro, your starting point is The Fundamentals. Although the title includes "Visual Studio", the majority of the book covers Visual FoxPro from the very beginning. It is specifically targeted at you folks who are coming to the Visual world from earlier versions of Fox. Note that The Fundamentals is only available in ebook (PDF) form, and we do not have plans to do a reprint or an update. For more books after The Fundamentals, check out "A comprehensive learning path for VFP" below.

Using DOS-based apps on Windows

Check out Alan Bourke's Painless Legacy FoxPro Applications on Modern Networks. (Ebook only.)

Learning VFP 7.0

If you specifically need to come up to speed on Visual FoxPro 7.0, your recommended path is both The Fundamentals (which covers VFP 6.0) and What's New in Visual FoxPro 7.0.

Learning VFP 8.0

If you specifically need to come up to speed on Visual FoxPro 8.0, your recommended path is the set of (1) The Fundamentals (which covers VFP 6.0), (2) What's New in Visual FoxPro 7.0, which goes from 6 to 7, and (3) What's New in Visual FoxPro 8.0, which goes from 7 to 8.

Learning VFP 9.0

If you specifically need to come up to speed on Visual FoxPro 9.0, your recommended path is the set of (1) The Fundamentals (which covers VFP 6.0), (2) What's New in Visual FoxPro 7.0, which goes from 6 to 7, (3) What's New in Visual FoxPro 8.0, which goes from 7 to 8, and you guessed it, (4) What's New in Nine: Visual FoxPro's Latest Hits, which goes from 8 to 9.

A comprehensive learning path for VFP

We often are asked for a series of books for learning VFP, or for a comprehensive 'starter set'. Here's what we recommend: First, The Fundamentals (and What's New in VFP 7.0/8.0/9.0) to learn VFP. Then, the Hacker's Guide (for 6.0 or 7.0, as appropriate) as the fundamental reference for the language (what many people think should have been the help file that comes with VFP). (We do not have plans to produce a Hacker's Guide for Visual FoxPro 8.0 or later.) Third is Effective Techniques, which gives you the big-picture strategy (or 'wisdom') for developing applications.

Fourth are 1001 Things (KiloFox) and MegaFox: 1002 Things, which give you answers and code to over a thousand granular "How do I..." questions. KiloFox covers 'inside' VFP while MegaFox covers VFP + the outside world. Two other books that address specific strategic issues are Advanced Object Orientation with VFP Apps and Debugging VFP Apps.

The rest of our books are highly specialized, covering topics like Office Automation, Client-Server Development, and the VFP Report Writer.

Printed books and ebooks

The purchase price of a printed book includes the ability to download the ebook at no extra charge. (Note that not all printed books have an ebook - see the catalog page of a specific book for details.)

Upgrading ebooks to printed books

Occasionally someone buys an ebook and then decides they have to have the printed copy as well. If you bought an ebook from us, here's how to upgrade it:

1. Fill out an order form here. Name, address, credit card info, including card security info.
2. Circle which book you want to upgrade, and write in "Upgrade ebook -> printed".
3. Fill in the cost:
a) Difference in price between ebook and printed (usually $10), plus
b) Shipping (about $5-7, depending on where we're shipping (UPS ground), plus
c) $10 handling charge
4. Send it to us via fax (414.332.9463) or email (orders AT hentzenwerke DOT com) (zip up the file - don't just send it in an email!)

We usually get these taken care of within one business day. Sometimes two. You'll get an email confirmation when it ships via UPS.

Site Licenses

If you purchased a single-user copy of an ebook, either with a printed book or by itself, you have a license to make as many copies for yourself as you need - on your home and work computers, on a laptop, a backup you keep in the safe deposit box, on your PDA, whatever. But this belongs to you and you only.

If your buddy asks you for a copy, tell them to buy their own. If your co-workers ask you to put it on the file server so multiple developers can access it, you will need a site license to do this. Giving or selling copies of this ebook to others is illegal and robs us and our authors of income that we have rightfully earned.

If you work in a multi-user shop and want multiple copies or a site license, you've come to the right place! A site license for an ebook allows you to place the ebook on your server and have multiple people access it, or have multiple people make copies of the same ebook for their own workstation or laptop.

A site license for a book is priced according to the following schedule:

1-5 people: 100% of the price of one printed book. (e.g. Your company buys a $50 book. Your company has five people who want to share the ebook that comes along with it. A site license that covers the additional four people (in addition to the original purchaser) would be an additional $50.)

6-10 people: 200% of the price of one printed book. (e.g. a site license for a $50 book would be an additional $100.)

11-25 people: 500% the price of one printed book. (e.g. a site license for a $50 book would be an additional $250.)

26+ people: 1000% of the price of one printed book. (e.g. a site license for a $50 book would be an additional $500.)

Online Order Form Promotion Code

Once in a while we run a promotion, like in a magazine advertisement. Those promotions have codes attached to them - and this box is where you enter that code.
