`The only way to squeeze those extra cycles out of the CPU is to make changes and
`measure the results. Abrash’s "Zen timer” has often been used for that purpose, but
`how accurate is it? Here’s a look at some problems this kind of timer has and how to
`improve it.

`Bug++oftheMonth..................................67
`It you use the delete operator, the compiler has to generate code to call the destructor
`for that object. But what if the compiler doesn't yet know whether or not you defined a
`destructor? Isn’t it a bug it it doesn’t warn you that it may be generating incorrect code?
`Yes and no, as this month’s non—bug shows.

`ver writers. This is especially true of bus architectures,- for
`example, it is extremely difficult to find good technical
`information about the PCI or PCMCIA buses. When I do
`manage to find an occasional hardware reference on the
`bookshelf, I almost hesitate to pick it up for fear of seeing
`the inevitable $89+ price tag. As a welcome relief,
`the
`MindShare series titles range from $19.95 to $34.95. At this
`price, I don’t feel bad spending the money on a book I
`might use only as an occasional reference.
`Ironically,
`though, my office copy of EISA System Architecture current-
`ly holds the title of ”most
`likely to be borrowed by a
`coworker.”
`
`The format of these books is quite different than that of
`the average computer book. Each book is based on a semi-
`nar taught by the author and that heritage is evident in the
`book’s structure —- it flows more like modules than chap-
`ters. Like most hardware books, they get right to the point;
`there are none of the self-indulgent authorial digressions
`that you see in some software development books. But,
`unlike most hardware books, these are actually readable.
`Most hardware references read like encyclopedias —- even
`the publishers don’t expect anyone to actually read the

`CAPRC ITIVE REACTANCE
`
`[Editor’s note: this review was provided by Paula Tomlinson.)
`I first discovered the System Architecture series a couple
`years ago at the bookstand that Computer Literacy always
`runs during the Software Development conferences. At that
`time, these books were published directly by MindShare
`and had very generic and nondescript black-and-white
`covers, so I almost overlooked them. I spotted the ISA and
`EISA books first. After leafing through them that night, I
`ran back to the bookstand the following day to buy any
`other books in the series, not dissuaded in the least by the
`prospect of hauling them back home with me. CardBus
`System Architecture is just the latest in this PC Architecture
`Series that currently totals 10 books. Addison-Wesley is
`now publishing these books with MindShare, so the more
`colorful cover art and wider distribution should ensure that
`
`you will be able to find them at any bookstore with a rea—
`sonable stock of computer titles.
`I admit that there are so few good hardware books avail—
`able that I tend to get enthusiastic about even mediocre
`attempts. But this series of books is truly an important part
`of my library. The series is generally based around proces-
`sor architectures and bus architectures (with a few miscella—
`neous topics such as Plug—and-Play). I find that most books
`that call themselves processor architecture books are really
`references for the assembly language instruction set of that
`particular processor. While those books fill a need, they
`don’t give readers an understanding of the overall hard-

`
`This is the second edition of this book, and in the PC pro-
`gramming book market, books rarely improve with time (in
`fact, they usually disappear after the first printing). The
`Windows 3.1 update of Petzold’s book was a disappoint-
`ment, the second edition of Marshall Brain’s Win32 System
`Services is mostly a name change that attempts to attract
`Win95 programmers, and there are other examples. This
`book is an exception because this edition is better than the
`first — much better.
`I reviewed the first edition of this book in December 1995
`
`column, and though it had some redeeming qualities, Ijust
`couldn’t recommend it. The writing was in dire need of edit—
`ing, the choice of topics didn’t always make sense, and its
`900 pages consisted of as much white space as useful infor-
`mation — the sort of general mediocrity you find in most
`programming books at your local bookstore. At Software
`Development ’96, I stopped by the WROX booth and heard

`entire book. For developers who do not already have a
`strong hardware background, this lack of truly readable
`information makes learning about the hardware a particu-
`larly daunting task. As long as readers bear in mind that
`some of the books are prerequisites for others, then these
`books should be accessible to developers with very little
`previous hardware background. In the front of each book is
`a chart that describes which books build on others. Some of
`them, such as PowerPC System Archicture, stand alone. But,
`for example,
`it’s recommended that you first read 15A
`System Architecture before reading EISA System Architecture.
`Although these books are not the most comprehensive
`references available on each topic, they are consistently
`accurate (several of them are already in their third editions)
`and very accessible to hardware novices. I would recom-
`mend them to anyone doing hardware design or support,
`as well as to any developers who write low-level system
`code (such as device drivers). I find the bus architecture
`books especially useful references.

`

` I may not know MFC, but I know a little about listview
`
`about their extensive efforts to revise this book and make it
`
`better. I listened politely, but with a lot of skepticism. If a
`publisher makes little money on the first edition, the book is
`usually abandoned. If it makes decent money, pouring that
`money back into improving the book is often not a priority,
`and make no mistake about it — quality technical writing
`costs money. This book seemed to be selling well for WROX,
`which led me to expect only inexpensive cosmetic improve—
`ments in the second edition. 50 it was with at least a little
`
`dread that I opened the box containing the new version of
`the book. Boy, was I surprised!
`As soon as I opened the book, I knew something was very
`different I love books, down to the way they feel and smell (I
`hope this is not due to some kind of addictive glue used in the
`binding), and something felt very different from the previous
`edition. They were the same shape and weight, so I got out
`the old version to compare. The difference was immediately
`obvious — the new edition has much more information
`
`packed into approximately the same number of pages. How
`can that be? Simple: most programming books are padded
`with white space, code, screen shots, etc., to achieve the spe—
`cific bulk (900 pages in this case) desired. In this new edition,
`the margins shrank, the font shrank, and the amount of infor-
`mation grew. Okay, they replaced the padding with content,
`but was the quality any better? I chose a topic I knew some-
`thing about and that I was fairly sure the book would not
`cover well: listview controls.
`
`
`
`
`
`
`
`
`
`
`
`
`controls. They have one of the goofiest designs of any Con-
`trol Microsoft has ever made. When the listview control
`needs the text to draw a particular item, it sends you a nofi.
`fication, and you are supposed to return a pointer to the
`string containing the text. Think about that. Your window
`procedure gets called asynchronously and asked to return a
`pointer to text. Obviously, your text had better not reside in
`a stack variable, or the listview control will most likely
`have a little problem on its hands! Just how long are you
`supposed to ensure that that silly pointer is valid? In fact, a
`Knowledge Base note says you need to keep it valid until at
`least two more messages arrive. I am not making this up.
`Even more incredibly, none of the books I’ve seen that dis-
`cuss the listview control (see, for example, the clear but
`superficial Programming the Windows 95 User Interface, by
`Nancy Winnick Cluts) describe this fundamental problem
`in its design. Much to my surprise,
`the author clearly
`describes this problem in the section on how to use MFC
`with listview controls. To my delight, where I have been
`unable to devise a reasonable workaround for this ugly
`listview interface, the author provides a workaround that is
`simple, effective, and no more distasteful than the problem
`it has to solve. I definitely did not expect to find a very
`handy piece of generic Windows programming information
`in an MFC book!
`
`Now I was hooked — I then compared the two editions in
`detail to see what had been changed or added. Start with the
`book title: this is a book about MFC, and now the title reflects
`that. The chapter on application architecture hierarchy is
`mostly unchanged, though there are a few new (and wel—
`come) pages on startup issues (registry usage, command—line
`parsing, etc). The text on the crucial subject of the docu-
`ment/view architecture shows only minor changes, but the
`two figures that describe SDI and MDI class relationships are
`significantly improved. That may sound trivial, but I found
`these new figures useful enough to copy and display where I
`can see them. The OLE coverage is beefed up. The important
`topic of the Windows 95 common controls is larger and more
`detailed now; listview controls got 3 pages in the first edition,
`but get 13 pages of much denser text in the second edition.
`The chapter on using the new common controls with MFC is
`by itself more useful than some entire MFC books I’ve seen.
`The parts of the book that remain largely similar to the first
`edition often have minor improvements scattered here and
`there.
`
`Is there still room for improvement? There always is, but!
`believe that the most significant point about this book is that
`WROX made a substantial investment in quality. These folks
`spent time and money to improve the quality of a book that
`was probably already making a profit. Not broaden the
`scope, not make it appear fatter, but improve the qualitY-
`And they succeeded! This may not be the only book you'll
`ever need on MFC, but it’s the best one I've seen and the only
`one I’m willing to recommend so far. I hope that readers Will
`reward WROX’s effort by buying this book, instead of the
`many inferior MFC titles on the market. Maybe we as con-
`sumers can send the message that quality really is worth
`investing in.

`File3, Edit2, etc.), which makes even simple code difficult to
`understand. Although they discuss exceptions, they employ
`almost no error trapping/handling. The front cover says
`”Learn what you need to get the Wmdows 95 logo on your
`programs,” but the authors acknowledge that they cover only
`a few of the requirements.
`In general,
`the explanations are unclear. Chapter 7
`("Object-Oriented Programming") contains two pages of con-
`crete information and thirteen pages of an abstract discussion
`of ”software engineering” (Grady Booch is ”God of all that is
`Object Oriented”). The authors define modal only as ”a win-
`dow that pops up to provide or request information" and
`assert that it ”is not .
`.
`. your application’s primary window.”
`Chapter 7 addresses the issues of conserving resources and
`space, but "space” is defined as disk space (not memory), and
`”resources” are defined as CPU cycles (not Windows
`resources or memory). No indication is given about how to
`conserve either.
`
`When writing for novices, precision and consistency in
`word choice are crucial. But the authors call a procedure a
`function (in the section in which they attempt to distinguish
`between the two) and refer to the TextOut() method as a
`property; they call a check mark before a menu item a check—
`box (six pages later they discuss the checkbox control); they
`refer to visual and nonvisual components as “visible" and
`”invisible." They claim that the TTable and T0uery compo—
`nents are ”ancestors of a dataset class” (they’re descendants).
`The authors are also forgetful: in Chapter 14, they promise to

`[Editor's note:
`From the dedication (in which one author thanks 24 people
`and their families and another thanks his wife and dog in the
`same sentence) to the appendices (a five-page ASCII chart and
`a five-page ANSI chart), this is a bad book.
`The authors say that no ”prior knowledge of writing code
`is assumed,” and they do attempt to define things such as
`”subroutine” and “variable.” In Chapter 8, they even employ
`”Mr. DOS," ”Mr. Windows," and ”Mr. Win32” to explain the
`”operating systems that Microsoft has released.” However,
`so many items are not explained, and so much material is
`inaccurate, that a true novice will learn little. Of course, there
`are descriptions and illustrations of every menu item, tool-
`bar button, and option. But there is no logical development
`in the ”course” material; pointers (which can be avoided for
`the most part with Object Pascal) are discussed on the fourth
`day (before the Project Manager) and the Visual Component
`Library isn’t discussed until 250 pages into the book.
`Chapters 3 and 4 are a “Readers Digest version of the refer-
`ence manual."
`
`Each chapter ends with questions and exercises that are
`pedagogically unsound. Often, the reader cannot possibly
`answer the questions based on the information in the chap—
`ter. One ”exercise” is to run Borland’s tutorial. Another
`
`requires the student to ”create a database application that
`uses all the data—aware controls.” And ”to demonstrate drag-
`and—drop to yourself .
`.
`. open Explorer and drag a worthless
`text file onto the Recycle Bin (make sure to retrieve it if it was
`an important file).”
`'
`The quality of the authors’ code is poor. The errors are
`numerous and are typical of novices and former BASIC pro-
`grarruners; they include (but are not limited to) using double
`instead of single quotation marks, using variables before they
`have been initialized, and omitting semicolons. In Chapter 4,
`there are 29 chunks of code (complete listings or fragments in
`the text), eight of these won’t compile and three of which
`don’t do what the authors claim. For example, the line
`
`Ilhile (I 0 'q') or (I O '0'
`
`) DO
`
`makes a simple get-a-key program run forever. All of the code
`is simple and most is inefficient. It’s available from an Internet
`Site (no disk or CD is included). The book’s cover claims that it
`is ”Endorsed by Borland International Inc.” and “Approved
`for Technical Accuracy” by two Borland employees. Clearly,
`Borland’s imprimatur is no assurance of quality.
`In Chapter 5, the authors devote three pages to the impor-
`tance of using meaningful variable names, but fail to heed
`their own advice: they use Delphi’s default names (Buttonl,

`discuss triggers in the next chapter, but don't; at the end of
`Chapter 16 they claim to have covered ”how to add graphs to
`your reports,” but they haven’t.
`In the Acknowledgments, the authors admit that the edi—
`tors made them feel ”like we were in English class again, but it
`was worth it!” In Chapter 18, they say that the ”Microsoft
`Developer’s Network CD .
`.
`. is the single largest wealth of
`information we have ever seen in one place” (what about a
`library?) Simply put, their writing skills are very weak. In
`addition to hundreds of punctuation, grammar, spelling and
`usage errors (89 fragments and run-0n sentences alone), the
`writing is vague, repetitious, and cliché.
