yes, it's true, but you can use a condition like this to deal with compatibility issues:

<? if (isset($_SERVER['HTTP_USER_AGENT']) && 				(strpos($_SERVER['HTTP_USER_AGENT'], 'MSIE') == true)) { ?>

I'm using z-index and I haven't see strange issues http://agec.ath.cx/lead maybe you could see a solution there

Web developer toolbar in firefox is a great tool to see CSS properties and change values on the fly.

SQL Server Express is "free", free in the meaning that you can download, install, test, personal use without the need to buy that rights. The copyright remain as Microsoft property, so you will need to accept a license agreement before installing because you cannot be able to sell a copy, make commercial software with this application, and another legal issues.

You could use for example z-index: -10; lower numbers will put an object in the background.

This is a source code example to calculate that expression with any value, you can test it at http://agec.ath.cx/eq, two functions to calculate each ± result, and one condition to put the two values (the real one and the imaginary) in the imaginary case (b < 4ac), tomorrow I'll inspect the code for errors and I'll add the graph.

why not to add the files using "Send to" option on contextual menu (right button), then you could access to your dvd from "My PC" then click on "Write these files to CD"... There are not many clicks

It isn't simple as you see it. You could reuse your database of your windows app (access, mssql maybe if exists) and display, modify the data through web but you will need a web developer.

If you want to see your desktop from web you could use a VNC server (has a java plugin), and forward the necessary ports from your router to your computer. And setup a dynamic dns redirector (Dyndns maybe). A technician can do so. In this way, you could access the app from web but not like a website.

yes, right logic. Also you can add a field in Users table to add friends separated by comma, you could use then explode function to separate the array and find again each user to find correlations. I think your solution is the best choice.

$form = "<td class=hr>";
$form .= htmlspecialchars(Town)."&nbsp;</td>";
$form .= "<td class=dr><input type=text name=Town maxlength=30 value=\"". str_replace('"', "&quot;", trim($row)) ."\"></td>";

echo $form;

Always use escaping \ when you use quotations inside another quotations, you could separate and concatenate items to deal then more clearly.

appart from sessions, you could use hash or random ids to reassert an identity coming from one computer

maybe you would like a tool like acronis director to resize partitions without losing data... there another open source tools but I'm not tested yet

You can look self-paced the PHP tutorial from w3schools (PHP is the most easier language) and then you can look feedback and contact form tutorials from Google to get a general idea.
Start using Dreamweaver 8, you can do DB queries easily and another stuff automatically. If you want to set programming as your primarly goal start learning PHP and OOP, use the ezsql class to create DB queries for example.
PHP are very documented, you could find more tutorials than another language.
