Featured: Choosing ColdFusion Hosting
There are many types of hosting. The primary packages available are shared,
virtual, managed, and dedicated. Shared hosting
normally includes many features for a low price. This can be attractive
but you may not need or use all those features. In a Virtual
Server, you own a portion of a server, you get a certain percentage
of processing time, disk space, bandwidth, etc. You have less risk of
being affected by neighbors but you will typically need more technical
expertise and effort.

a shelf life. You may have information that you want up after a certain
point in time or you may want it to be gone after a certain time.You may
want to have it appear and disappear without having to be editing files
or changing out input in some back end system. You will find that you
can build a simple system for publishing and removing info with ColdFusion's
CFIF tag and CreateDateTime() and Now()

ColdFusion has you covered with its grouping capabilities.

CFPARAM and How to Uncheck a Checkbox
For anyone new to application
development, you may be perplexed when you create your form for editing
some data that should allow a user to uncheck a checkbox and update a
record to a status of not checked. You will sooner or later discover an
oddity about HTML forms. HTML forms won't allow you to uncheck like you
think you should be able to. If you uncheck the checkbox, the value becomes
NULL and the form doesn't bother to pass the field. You will find that
does have a simple solution and much more with the CFPARAM tag.

custom tags are ColdFusion templates just like any other CFML file but
are designed to be reused. Coders can save much time by packaging code
that is used frequently or can easily add functionality by using free
or inexpensive custom tags. There are two general categories of custom
tags, one uses only ColdFusion's CFML code. The other packages C++, Java,
or other languages into a custom tag that is used by ColdFusion. We'll
cover only CFML based tags in this article. For our discussion we will
be using CF_States

We all start out learning ColdFusion by outputing variables using CFOUTPUT and
some pound signs. A variable with an name like myvariable was passed to the page
by a form or a link and output as #myvariable#. By not understanding and using
scope, we unwittingly add inefficiencies to our code and overlook a lot of advantages that
come with using scopes.

As a newbie, you can expect to hear comments about "newbie tags".
You may hear "Oh, I'd never use CFINSERT or CFUPDATE, I only use
SQL within CFQUERY". If you follow a discussion on this you won't
see any strong technical cases against them and when I've pushed the discussion,
it ends up being admitted that problems haven't been seen since 4.5 but
"SQL is much more flexible and powerful".
