Fool me twice, shame on me

Ok, I'll admit, a long time ago I clicked on a link that was in an e-mail message and that led to a web page exploit that took advantage of a security hole in Internet Explorer 5 (hangs head in shame).

Now there's a flurry of new e-mails crafted to look very much like it came from Microsoft and supposedly has a security patch as the attachment. Well, of course, that attached file is infected (the one I got contained the 'Swen' virus).

What really tips it off to me is the poor grammer and lack of proper capitalization in the body of the message. I mean, really, would a large corporation like Microsoft send out such a poorly written message?

Subnetting Class-C IP addresses in a home network
Network security has become a large concern for even the avid home internet user. With more and more wireless routers and broadband connections out there connecting to the internet there is one thing that you can do to help isolate your private computers from the internet and still allow them to access the web. All you need are two standard home-use routers. I prefer the Linksys ones but any that are configurable for NAT will do.

Subnetting :)

Take a look at this network page from TCPIPPrimer.com to help you split up your current Class C network into 4 separate networks (Daryl says 2 but with this configuration, you can do 4), each isolated from each other yet all accessible to the internet.

Mini-tutorial on DOM
While experimenting with some JavaScript, I wanted to create a button that would change the background color of a web page. The result is a good example of the "Document Object Model" that most new designs are based on today. Using the "onClick" function of the button, the new hexidecimal color code is passed to the browser. Adding an inline style to the button code, the button's color matches the color the background would be changed to.

Here's the page: Changing Background Colors

Look ma, no tables!

Unless you've been on the moon the last couple of years, one cannot help but notice the trend towards using CSS rather than the <table> tag in page layouts.

Another web exploit

There's a little "bug" that effects every version of Windows since Win98 and allows a malicious web page to execute code. Of course, we all know what havoc this can play on your computer. The most nefarious method is to send the malicious page via e-mail after which some e-mail clients will preview the page and let the code execute.

ASP.NET 101: PostBacks

So, let's go down the .NET path and explore some of the new things that are available. First off, designing and posting to web-based forms has taken on a new dimension. You can write code to add function to your page and simply post back to the orginal .aspx page. At the same time, let's introduce the asp:panel tag. Rendered by the .NET server as a DIV, you can call each panel by it's ID attribute inside your code.

In this first example, let's make a simple form to collect a user's information. When the form is submitted, we will hide the original form and replace it with a new asp:panel containing new HTML created with the newly gathered data. So, make the first panel visible like so: asp:panel id="panelSurvey" runat="server" Visible="True" and further down the page, make the second panel hidden asp:panel id="panelAfterPost" runat="server" Visible="False".

In our VB code, we will simply swap the Visible attribute:

script runat="server"

	Sub Button_Click(sender as Object, e as EventArgs)

		If Page.IsPostBack then

		panelSurvey.Visible="False"

		panelAfterPost.Visible="True"

		End If

	End Sub

/script

Site Updates
Nobody really complained, but the Archive section was not formatted very well and, as a result, was not being indexed for searches. I've corrected this little oversight and thus you can use the search tool to glean through the old posts.
