A comment on using CFParam inside a CFFunction

Posted At : January 27, 2010 10:50 AM | Posted By : Andy Jarrett
Related Categories: ColdFusion

This is a response/comment to Steve Goods post named: Using CFParam Inside a CFFunction. Its turned into a blog post because, well I suppose I am looking for a wider feedback on my thoughts.

When it comes to using <cfparam> in a <cffunction> I would never of even contemplated it up to a few weeks ago, mainly because of the framework I was using gave me other ways of checking of variables existence.But I've moved over to Framework One (FW/1) which uses the tag in its controllers for some of the demos and I've now adopted this in to my recent code.

This then got me thinking that I cannot find a solid case reason as to write

if ( NOT StructKeyExists(myVar, "somekey") )
{
myVar.someKey = "0";
}
else if ( NOT isNumeric( myVar.somekey ) )
{
throw();
}

1  if ( NOT StructKeyExists(myVar, "somekey") )
2  {
3  myVar.someKey = "0";
4  }
5  else if ( NOT isNumeric( myVar.somekey ) )
6  {
7  throw();
8  }

when cfparam does that all in one go with basic type checking aswell.

<cfparam name="myVar.somekey" default="0" type="integer" />

1 <cfparam name="myVar.somekey" default="0" type="integer" />

You could wrap the if() logic in a function to be used but then aren't you just adding an extra layer to your code to do something CF already handles?

Submit jQuery tabs back on to itself

Posted At : January 26, 2010 9:16 AM | Posted By : Andy Jarrett

jQuery UI is a powerful set of interaction plugins for building RIA apps that run and the look the same across multiple browsers. Below is an example of using the tabs to hold multiple forms which submit back to themselves. The code is pretty straight forward and consists of two pages, the first one can even be a HTML page but the second one in my demo is a ColdFusion page to show the passed variables.

$('.inlineForm').live('submit', function() {

The second page should be called receive.cfm

All 32-bit windows hackable

Posted At : January 23, 2010 7:15 PM | Posted By : Andy Jarrett
Related Categories: Microsoft

It seems that there is a hole in the Virtual DOS Machine that is used to run 16-bit applications in all version of Windows from 3.1 up to and including Windows 7 (SP1 too). The hole basically allows a user with restricted access to execute code at system privilege level. The fix is easy (if you don't run 16 bit apps), its simply a registry change. According to the article though Microsoft have known about the issue since mid 2009 which is kinda scary. You can read more at http://www.taranfx.com/windows-hacking. Why couldn't an exploit as serious as this be found for all IE6 versions!

Fridays Joke: The hippie

Posted At : January 22, 2010 12:28 PM | Posted By : Andy Jarrett
Related Categories: Fun

A hippie gets on a bus and spies a pretty young nun. He sits down next to her, and asks her: "Can we have sex?"

"No," she replies, "I'm married to God." She stands up, and gets off at the next stop.

The bus driver, who overheard, turns to the hippie and says:

"I can tell you how to get to have sex with her!"

"Yeah?", says the hippie.

"Yeah!", say the bus driver. "She goes to the cemetery every Tuesday night at midnight to pray, so all you have to do is dress up in a robe with a hood, put some of that luminous powder stuff in your beard, and pop up in the cemetery claiming to be God."

ALTER TABLE tablename AUTO_INCREMENT = 12345

1 ALTER TABLE tablename AUTO_INCREMENT = 12345

Changing BlogCFC's comment approval

Posted At : January 21, 2010 12:35 AM | Posted By : Andy Jarrett
Related Categories: Blogging

One little thing thats bugged me with BlogCFC with moderated comments is the need to go from List > View Comment < back to list to approve. Silly I know but still ... So I've added the following on the comment.cfm page in the admin section

<input type="button" name="approve" value="Approve" onclick="location.href='#application.rooturl#/admin/moderate.cfm?approve=#comment.id#'" />

1 <input type="button" name="approve" value="Approve" onclick="location.href='#application.rooturl#/admin/moderate.cfm?approve=#comment.id#'" />

All this does is add the button "Approve" to the view comment page to smooth out the flow of the process
