World Wide Pizza
There is absolutely no doubt that the best thing to happen to the world since sliced bread is the World Wide Web!  Here's the proof:  I can now be sitting at my computer, typing in commands to which computers around the world will respond (such is my job) and when this tires or bores me, or when I feel a tad peckish, I can simply type in a few more commands to which computers around the world and my local pizzeria will respond!
I did this a few minutes ago and am now awaiting an extra large with all my favorite toppings.  How great can it get? -- I don't even have to leave my chair before someone will bring me everything I need to gain far more weight than my body should carry!  Along the way, however, I couldn't help but notice something that irked my sense of professionalism.  "I have to tell my readers," I thought, "in order to help them avoid this pitfall."  And so, (and while I'm at it, let me quickly apologize for gratuitously advertising my personal favorite pizza delivery company, but it's necessary so that you can see for yourself what I'm talking about) here it is:
I went to www.papajohns.com, put in my email address and password and clicked on their "Order Online" link.  They have a great menu system whereby you can check out their specials, order by size or type of pizza, select drinks or extras, everything you could want, easily laid out.  If you choose to create your own custom pizza, you get to select size and crust type and add toppings either in half pizza or whole pizza ranges.  (It occurs to me that if I was to order, for example, three half toppings, how would they know which ones were to go with which?  Clearly there could be quite a number of variations!)
Having selected the pizzas, drinks extras, etc., that are needed you proceed to checkout -- all standard shopping cart stuff, all working very well.  At the checkout summary page, you can add a tip for the driver, select your payment method and proceed.  I chose credit card, put all my CC info into the secure page (having checked the certificate, of course --- <G>) clicked confirm and received the confirmation page.
The confirmation page showed me Amount, Delivery Charge (yes, believe it or not, they charge for delivery!), Sales Tax (unlike some countries, in the US the sales tax is always added as a separate item after totaling the pre-tax charges) and Grand Total.  Here's the problem..... I couldn't remember if I added the tip for the driver!
I had seen the total for the items ordered on the checkout summary page, but with my mouth beginning to water in anticipation, I hadn't been paying that much attention to it.  What irked me a little was that while I had previously seen the sub-total amount for the items ordered, I was now being presented an "Order Amount" that included the tip.... if I had entered one.  I now had no way of checking.  If the confirmation page had carried the tip as a separate item along with the other non-item-ordered amounts, as it had been on the summary page, I would not have had the problem.  As it was, I had to call their customer service phone number to find out.  Now, you know how much I enjoyed that!!
The problem is a simple, little, and I'm afraid too common, slip in the programmer's mind (or programmers' minds.)  For just that one moment, they forgot to see things from the buyer's perspective, and continued with things from the computer's logical accumulation of information point of view.
A tiny slip that resulted in the need for a phone call, which needed a person to answer it and look things up on another computer, etc....  all of which wasted money that could otherwise have allowed a little extra sausage on my pizza.  Clearly you can see what kind of disaster that is!
Thanks for reading!

Q & A Goodies
Questions are taken from submissions to our Community
Mentors. You can ask a Mentor a question by going to
Q. I'm making a website with a "fixed" background.  I can't figure out how to make the picture fit the browser perfectly on everybody's system.  Is there a code I can place inside my document to alter the fixed background to fit the browser?  My site content will go into a smaller screen/box within the background so there is no need for scrollers on my outside browser and my background image doesn't need to be tiled because it basically is my site.
A. You can use Cascading Style Sheets to fix a background image. The code would have to be edited for your particular situation and image but here is the code:
<style type="text/css">
body {
background-image: url("/images/your_image_name.gif");
background-repeat: no-repeat;
background-attachment: fixed

Q. I am trying to figure out how to make a check box on an HTML form checked by default.
A. If you want a check box to be checked when the page opens you can do it without JavaScript like this:
<input type="checkbox" id="ckbox" checked>
With JavaScript you can set the checked property to true when the page loads like this:
<script type="text/javascript">
The above will work if there is only one checkbox.  If you have multiple checkbox's with the same name then you have to specify itslocation in the array like this:
<script type="text/javascript">
The above would set the first checkbox's checked property to true.

Q. I am looking for JavaScript help in order to pre-select a option in a select field inside a form.  I am using server-side scripting (PHP) in order to provide the selected value.
A. You could use PHP to create your option tag and select the option you want that way.  I have a small Help Desk application written in PHP that I have set up dropdowns to select the date.  I have them default to the current date.  Here is an example of the dropdown for the
<select name="beg_req_month">
           {print "<option value='" . $i . "' selected>" . $i .
           {print "<option value='" . $i . "'>" . $i . "</option>\n";}
The variable $prob_month is set to the current month in some previous code.  For Javascript to set the selected option you would use a statement like this (which sets the first option tag to selected):
[Beware of the period following the less than symbol in the "for" statement above -- this is one of the periods inserted as a part of the technique mentioned in the note at the beginning of this section & does not belong in the code you execute -- Ed.]


Q. Is it possible to change the link color with the onMouseOver command?
A. Yes it is.  I have done it using JavaScript (there is also a way using CSS).  Here is my JavaScript version:
<title>Change Link Color</title>
    <style type="text/css">
      /* Set colors for IE5.0+ and Netscape 6.0 */
     .textRed {color:red}
     .textBlue {color:blue}
     .textLgreen {color:lightgreen}
     /* Set colors for Netscape 4.0+ */
     /* No underline on link for all browsers */
     <SCRIPT LANGUAGE="JavaScript">
       /* This script was written by Jim Young of www.requestcode.com and has been tested in Internet Explorer 5.0+, Netscape 4.0+ and Netscape 6.0.  I use the statement (this.className) to  change the class for the links in NS6 and IE5.0+ .  The scripts below are strictly for NS4.0+ . Add links below that are in the same order as your links in the body section.  the format for the array is:
           page to link to, the link name(what is displayed on your page), div id, class(color) for the mouseover, and class(color) for the mouseout.
Make sure you separate them by a comma (,).
    var links = new Array()
          links[0]="http://www.wsabstract.com,Website Abstraction,divLink0,over,normal"
          links[1] ="http://www.requestcode.com,Requestcode,divLink1,overb,normal"
    //  Unless you absolutely have to DO NOT change the functions below.
    function change(linknum)
           if(document.layers)  // Check for NS4.0+
              linkval=links[linknum].split(",") // split out the values
              var linkd="<A HREF="+linkpage+" CLASS="+linkclass+" onMouseOut=changeb(\""+linknum+"\")>"+linkname+"</A>"
              var docwrta="document."+linkdiv+".document.write('"+linkd+"')"
   function changeb(linknum)
            var linkd="<A HREF="+linkpage+" CLASS="+linkclass+"
onMouseOver=change(\""+linknum+"\") onMouseOut=changeb(\""+linknum+"\")
            var docwrta="document."+linkdiv+".document.write('"+linkd+"')"
      /* If you add more links here make sure you update the links array with the same url and other required information.  Make sure they are entered in the array in the same order as they appear on your page. Also remember to change the value being passed on the mouseover and mouseout to the functions to match the entry in the array.  Make sure you use different names for each div.  In the mouseover for IE and NS6 you can change the class name specified by the statement this.className to a color you have setup in the styles area in your head section above.  You should leave the class(color) for the mouseout the same as when your link is displayed when the page is first loaded.  I currently have them set to blue which is the class normal.
<H1>Link Effect Example</H1>
Run your mouse over the links to see them change color </CENTER> <div id="divLink0" style="left:15; position:absolute; top:90; visibility:visible">
 <a href="http://www.wsabstract.com" onMouseOver="change ('0');this.className='textRed'" class="normal" onMouseOut="changeb ('0');this.className='textBlue'">Website Abstraction</a> </div> <div id="divLink1" style="left:15; position:absolute; top:120;
 <a href="http://www.requestcode.com" onMouseOver="change ('1');this.className='textLgreen'" class="normal" onMouseOut="changeb ('1');this.className='textBlue'">Requestcode</a>

Q. How do I lose the blue line that appears round an image when I make it a link?
A. In the IMG SRC tag add this:

Q. Is there any way to place text on top of pictures?
A. Here is the link to see how that's done: http://www.htmlgoodies.com/tutors/textonimages.html

Thanks a lot for all the support for my position on software piracy -- when I think about the fact that my livelihood depends in part on software buyers' honesty, I am reassured by those responses.
I must send a quick message to Andrew B. in response to his comment which, while not the only one in the same vein, was one in a tiny minority.  Andrew says,
"First off all, software Pirates are not straight out thieves. They take a couple dollars from multibillion dollar companies. Unless everybody starts pirating files, the music, video and software industries will still make a fairly decent profit (billions of dollars). I pirate software because it is outrageous to pay $170 U.S for Windows XP pro. I could get a decent computer with Linux for that price. If companies stated charging less for their digital products I would consider switching to legal methods. I tunes is a start but it is still very expensive. Fortunately Bill gates, being a multibillionaire, will not be worried about losing a few bucks, or in his eyes a couple pennies."
It's not Microsoft you're stealing from, Andrew (and even less Bill Gates!) It's me, and your neighbors, and your friends.  Microsoft does not simply suffer the loss of revenues due to piracy, nor do they simply suffer the cost of their anti-piracy campaigns or legal costs involved in seeing pirates charged.  They add those charges into the cost of their products, and we all pay for them -- just the same way that we all pay for items shoplifted out of our local stores.  Please don't make the mistake of thinking that a crime is OK because you believe the victim can afford it.  Software pirates are thieves -- criminals -- and we are all their victims.
Thanks for all your feedback!

Windows Tech Goodie of the Week 
Working with Databases in ASP.NET 2.0 and Visual Studio 2005
In this article we'll look at how to connect and display data from a database in ASP.NET 2.0. Specifically, we'll see how to use both the programmatic and declarative approaches for accessing data, as well as the basics of displaying data using the GridView control. Read on to learn more!

Simple Database ASP.NET Sample Code
It seems you can never make code simple enough. No matter how many database related samples I publish, I'm always getting requests for simpler ones.
Well, this one is as simple as they get. This script connects to our SQL Server database, executes a basic query, and drops the results right into a DataGrid. You won't find any fancy formatting or cool tricks in this sample, just straight-forward code -- plain and simple.

An Examination of Visual Basic's Random Number Generation
In this article Mark Hutchinson takes an in-depth look at Visual Basic's pseudo-random number generator. In particular, he discusses the Randomize, Rnd and Timer functions, why the numbers generated aren't really random, and what that means for your applications.
And Remember This ...
1984 Baby "Fae" died
At the Loma Linda University Medical Center in Loma Linda, California, doctors attempted a radical procedure to save the life of an infant, dubbed "Baby Fae" to protect her family's privacy.  Baby Fae had been born with a heart abnormality which almost always resulted in death.  Heart surgeon Dr. Leonard L. Bailey persuaded her parents to allow him to try an experimental Baboon heart transplant procedure.  Previously, three other patients had received animal heart transplants, but none had survived more than eighty-four hours.  Dr. Bailey felt that an infant like Fae would have a better chance since their immune system was less developed and would not be able to reject the heart so easily.  The operation was performed on October 26, 1984, when the infant was fourteen days old.  Initially, prospects were positive.  After a couple of weeks, however, her body's rejection of the alien organ began to build.  The required increase in immunosuppressive drugs caused a kidney failure, and eventually led to a heart failure which, on this day in 1984, proved fatal.  She lived for twenty days.

Today was also the day that in: 1763 Charles Mason and Jeremiah Dixon began surveying the line between Pennsylvania and Maryland (the Mason-Dixon line); 1777 the Articles of Confederation were adopted by the Continental Congress; 1806 explorer Zebulon Pike sighted Pike's Peak; 1932 the Walt Disney Art School was created; 1939 the US Social Security Administration approved its first welfare check; 1957 Soviet spy Rudolf Ivanovich was sentenced to 30 years and $3,000 fine in the US; 1969 250,000 protesters held a peaceful demonstration against the Vietnam War in Washington DC; 1969 Janis Joplin was accused of "vulgar and indecent language" in Tampa, Florida, US; 1982 Funeral Services were held in Moscow's Red Square for Leonid Breshnev; 1983 Turkey proclaimed the "Turkish Republic of Northern Cyprus"; 1988 the Palestine Liberation Organization (PLO) proclaimed the State of Palestine, recognizing also the existence of the State of Israel;

Born today were: in 1708 the "Great Commoner" and twice UK Prime Minister, William Pitt the Elder; 1738 discoverer of Uranus, astronomer Sir William Herschel; 1815 painter of the world's largest painting, the "three mile canvas", John Banvard; 1882 Austrian, and US Supreme Court Justice, Felix Frankfurter; 1891 WWII German African Campaign Field Marshall Erwin Rommel;  1905 Italian orchestra leader Mantovani; 1919 Louisianas "People's Court" Judge Joseph Albert Wapner; 1923 English actor Peter Hammond; 1929 actor Edward Asner; 1931 actor John Kerr; 1932 English singer Petula Clark; 1933 comedian Jack Nurns; 1934 actress Joanna Barnes; 1937 actor Yaphet Kotto; 1939 actor Thalmus Rasulala; 1945 Swedish musician Anni-Frid Lyngstdad (ABBA); 1954 actress Bevery D'Angelo; 1977 9th in succession to the throne of the United Kingdom Peter Mark Andrew Phillips;
