Nov 30, 2006Have you ever heard the saying “If you don’t know where to look, don’t look at all”? Think about this saying and coding. If a piece of code somewhere in the system is
causing an error, don’t split the whole thing apart to find it. Know where to look
for it before you cause even more damage.
The same principle can be applied to new features, functions or methods you want to
create in your application. You know exactly how the feature has to work and you start
coding. A...

Nov 28, 2006There are two reasons why it is desirable to do so. The first is for letting
search engines see more of your content rather than the big portion of ViewState many
sites have. The other is perceived rendering time, which means that the content loads
faster because it renders before the ViewState while the total rendering time remains
the same. That will decrease the load time of your website’s content.
Techniques to move the ViewState to the bottom of the WebForm has ...

Nov 27, 2006On a website with the ability for users to logon, it is a good idea to have some sort
of password policy. The most widely used contains minimum requirements for the length
of the password and that the individual characters must be a mixture of numbers, letters
and special characters. This is pretty much standard and they make it much more difficult
to break into your system.
Eventually, these passwords will be broken and for a brute
force robot it’s only a matter of t...

Nov 27, 2006Today I had to add some functionality to an already existing class library. In there
were a internal virtual method that I thought were supposed to be protected virtual.
To no big surprise, I couldn’t compile after changing it to protected. I didn’t want
to make it public so I thought of combining the two accessors with no hope for it
to work.
internal protected virtual void SomeMethod()
{
DoSomething();
}

Nov 22, 2006The W3C has introduced an API for
their HTML Validator. It is not a SOAP web service, but it does return XML that can
be parsed, so now you have the ability to incorporate validation to any web application, Windows program or wherever you want. It works just as the normal validator, by specifying
a URL, but you have to add the “output=soap12” parameter to the URL like so: http://validator.w3.org/check?uri=http://www.google.com&output=soap12.
I’ve been playing a littl...

Nov 21, 2006I recently realized that you can add more than one class to a single HTML element.
This opens up to even more structured stylesheets and more code reuse. It’s a standard
and has cross-browser support. You simply just separate the classes by a space like
so:
<div class="warning
headline">
The nice thing about this is that you can refactor your stylesheet even more and thereby
avoid duplication.
.warning{
color: red;

Nov 20, 2006There is no doubt in my mind, that ASP.NET is the most powerful and versatile platform
for web applications at the moment. By leveraging the .NET Framework you can do absolutely
anything in no time, but is that power also the problem with ASP.NET?
In the dark ages before ASP.NET, we were stuck with ASP and PHP but we were just as
enthusiastic about them as we are with ASP.NET now. They were relative easy to learn
and to learn well enough to do something really cool with i...

Nov 17, 2006Office pranks are among the funniest and we’ve probably all done some of our own over
the years. This time, my boss and I came up with a good one. Write an add-in for Windows
Live Messenger that auto replies to all incoming messages. We would then install it
on a co-worker's computers when he goes to lunch. We would define some sentences
that by random is sent to the sender of any incoming message.
Building the add-in
To our big surprise, this was the ea...

Nov 16, 2006The Session in ASP.NET is a very simple way of storing user specific data for the
duration of a single user session. I’ve many times added data to the Session that
had an even shorter lifespan. That could be as a data store for properties on AJAX
enabled web pages and those properties don’t belong in the session after the visitor
navigates to another page on my website. To clean up, I would then delete those session
objects that no longer is in use.
There are two way ...

Nov 14, 2006For a website that supports multiple languages, it is important to tell the client
what the selected language is. This is done in the <html> tag in the lang or
xml:lang attribute and could look something like this for an XHTML document:
<!DOCTYPE html PUBLIC "-//W3C//DTD
XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en-US">
The DOCTYPE and <html> t...
