ColdFusion Tips and Tutorials

I. Comments:

I am having fun with a new product... well this product is not new, it is just new to me.

HTML/OS (http://www.htmlostips.com)

I created the website because I think it is very cool and a great tool to use. The company at http://www.aestiva.com has a new book out that gives you a evaluation copy of HTML/OS to play with. I have purchased the book in advance at Amazon. The release date is around the corner so you could have your own copy of HTML/OS to play with and create applications.

Ok... Ok... Why is HTML/OS so cool? HTML/OS is similar to ColdFusion however it has features that are totally different. For example the most radical but very useful one is the fact that the database is in the application. So when you create an application for sale you can truly sale the application and keep the code safe from being copied. For example to when you create an application you can make it where it will not work but on ONE domain. This keeps people from coping your app and using it everywhere. Also when encrypting it uses your domain name and the domain name to which it will be placed to create the unique key.

Database Reset
One way to regain control of a hung datasource is to send it a query that will cause a database error. Here is such a query. It doesn't look like much, but it can save you a half-hour or so waiting for a connection to drop naturally. I call it bumpdb.cfm.

<cfquery name="bump" datasource="context">
select
</cfquery>

Memory Reset
Suppose your code writes to a memory variable and you want to remove the variable so you can start fresh. Here's an example that will do that. I called it noticeaq.cfm; because, I wanted to quit working with an application variable named "notice".
It doesn't clear the entire structure. It deletes a specific element from the structure. Remember if you're emulating this approach that application and session variables are contained in structures but that client variables are not. (They "fake it".)

<cfapplication name="Notice" sessionmanagement="no">
<cflock name="crasher" timeout="30">
<cfset dummy=structDelete(application,"Notice")>
</cflock>

I hope these hints help you when you need it most. Happy Hunting!
