Getting It Right
I remember watching a documentary some time ago, that showed a bird that had learned to pick up stones and throw them at eggs to crack their shells, allowing the bird to eat the contents of the eggs.  The commentator pointed out that this is the only bird we know of that uses a tool to accomplish a specific task.
I pondered for a while, the learning process this species had to go through.  At some point, it must have had the inspiration to pick up a stone and drop it.  My guess is that it had to have been really lucky on that first try, and cracked the egg; otherwise, why would it try again?!!  It had to have repeated the process many times over, gradually learning that throwing the stone with a jerk of the head yielded a higher rate of success than merely dropping it.  There also had to be a whole bunch of them around at the time, so that the species could learn the process, rather than just a few individuals.
And as I pondered, I thought about how close that learning process is to the way we learn to build websites.  We, however, have the distinct advantage on knowing in advance that we will be going through a learning process, and that failures are an anticipated part of that process.  This enables us to fast track through -- acquiring skills at a much faster rate than the bird does; which is probably why the birds still can't build websites!
Once inspired, the bird marveled at its initial success.  So should we, no matter how humble the success might be.  The only requirement for continued success at that point is to continue.  It is not necessary, or even desirable, to try to learn it all at once.  Instead, learn one new thing and incorporate it into an existing effort.  Next learn another, and so on.  There is a great danger of becoming overwhelmed by failures if there are too many detailed items in the project for each to be learned in succession.
In this process, it is less important to get it all right than to get it done.  Getting it right comes with time, and is a naturally occurring
 feature of a repeated process.  Keep those websites coming!

Q & A Goodies
Questions are taken from submissions to our Community
Mentors. You can ask a Mentor a question by going to
Q. I am constantly creating files (pdf or word) files that I need to show to many co-workers. Instead of having to email everyone everytime I finish a file, I would like to upload the file to my server and have them view the list of files online and download the ones they want. These files need to be password protected as different people in different departments should only see files pertaining to them. Here was my idea, create a bunch of password protected folders on a server - one for each department, and I will upload the file to any folder that should be allowed to view these files.  Two questions: 1) I put the files in a folder, but when I try to view the folder in a browser it tells me I don't have permission to access this folder (I assume because I never created an index file). How can I set it up that I should be able to view a list of files that are in the folder?  2) how can I create a page that will allow me to upload files to folders using a browser?
A. I believe you are correct in that you do not have an INDEX file for the server to show when you try to access the folder. You could create an INDEX file with the links to the documents for downloading. I am assuming that you have already password protected the folder? An even easier way would be to use a password log in feature for your pages. The application would allow users to sign up themselves and you would control which group the user should be in and only the documents or files you allow each group or person to view. There is a nice web application called ASPLogin. It has to run on a server that supports ASP. For example, to make a document available to all users in a group called 'management', members of a group called 'administrators' and a user called 'fred' (who may or may not be in either of the groups), you would add the following code to the top of the document:
<.%@ LANGUAGE=VBScript %>
Set asplObj=Server.CreateObject("ASPL.Login")
Set asplObj=Nothing
Any other group or person trying to see that document will not be allowed to see it. It is a pretty slick application You can take a look here: http://www.asplogin.com
To create a page to allow you to upload documents would call for some scripting. This all depends on what type of server you site is hosted on. If it is a Windows server then it will support Active Server Pages (ASP).

Q. Is there a way of naming spans partly with a variable? I.e. insted of doing this:
 document.all.sp1.innerHTML=('<img src=pt1.gif>');
 document.all.sp2.innerHTML=('<img src=pt1.gif>');
 document.all.sp3.innerHTML=('<img src=pt1.gif>');
 document.all.sp4.innerHTML=('<img src=pt1.gif>');
 document.all.sp5.innerHTML=('<img src=pt1.gif>');
 document.all.sp6.innerHTML=('<img src=pt1.gif>');
 document.all.sp7.innerHTML=('<img src=pt1.gif>');
 document.all.sp8.innerHTML=('<img src=pt1.gif>');
is there any way like:
 for( var n = 1; n < 9; n++)
 document.all.sp + n + .innerHTML=('<img src=pt1.gif>');

A. You could try to use the eval() method like this:
 eval("document.all.sp" + n + ".innerHTML=('<img src=pt1.gif>')");
Q. I want to have a small window open when someone clicks a link on my page.  I don't want a full size window, just a small one.  Can JavaScript do this?
A. Since you will probably have more than one link on a page you should set up a function in your head section of your document that will be used by multiple links.  You can pass the html page you want to load in the window to the function when the link is clicked on.  With window.open() you can set the
width, height, postion and other attributes.  Here is an example:
<.script language="javascript"> function OpenWin(linkid)
    {  NewWin=window.open (linkid,"newwin",config="width=200,height=250,location=no,status=no,directories=
The variable "linkid" contains the page you want to load.  This was passed to the function when the link was clicked on.  Then in the body section of your document your link could look like this:
<.A HREF="javascript:OpenWin('somepage.html')">Apples<./A>
You would wrap the link around the word that you want to click on for more info.  The HTML Goodies site does have a tutorial on window.open()
(see http://www.htmlgoodies.com/primers/jsp/hgjsp_11.html and http://www.htmlgoodies.com/primers/jsp/hgjsp_12.html  -- Ed.)

Q. I  have been working on trying to come up with a better menu for my index page. I used Sothink DHTMLMenu to generate one. I have it working, but it takes quite a while for the menu to load. What is my problem?
A. I can't see your menu, but I can make a couple guesses. You have a bunch of images that need to load to make the menu work. The browser looks for them when you do your mouseover, which means calling the server and asking for the image, and repeating the process for each image. My first guess is you could fix your problem with a preloader, so the images are already in the browser cache. Here's an example of a preloader:
// preload images
        var an_image1 = new Image(151,37);
        an_image1.src = "images/navigation/options_home_over.jpg";
        var an_image2 = new Image(151,37);
        var an_image3 = new Image(151,37);
This is a JavaScript that declares a variable as an image and specifies the size so the browser doesn't have to figure it out, and then give the variable a value consisting of a URL.
My second guess is that your images are large and taking a long time to download. Keep them small, like 3k each, or even eliminate them if you can.
Get rid of the "best viewed at" message. No visitor will change their screen setting just for your site, nor take the blame for he site not working at their screen setting. You just have to make it work at different sizes.

Building an Enterprise Service Bus to Support Service Oriented Architecture
In this article, Joseph Poozhikunnel defines an Enterprise Service Bus (ESB) that can be created to support any Service Oriented Architecture (SOA) adopted by an organization.  The type of ESB required could vary as there is no "one size fits all", therefore the article examines a few of the mechanisms available that could be adopted to implement an ESB.

Proper Case ASP.NET Sample Code
This is an ASP.NET version of ASP 101's classic ASP Proper Case sample.  It was originally written to provide a simple alternative to VB's StrConv function which was unavailable in VBScript.  Now that ASP.NET have given us access to full blown VB, the sample includes the StrConv method for comparison.
