Determining Which Function Called This Function (Using ColdFusion)
Posted: November 16, 2006 at 9:21 AM by Ben Nadel
I was just looking through my CF-Talk emails, when Tom Chiverton dropped a bomb shell on my brain. Someone had asked how to find out which function was calling a given function. Sounds complicated right (to me it does, so back off!)? But Tom was all like, oh, that's mad easy, just thrown an error and catch it. What?!? It's that easy? I, of cour... read more »

Posted: November 16, 2006 at 8:20 AM by Ben Nadel

SQL Data Types Returned From GetMetaData() Are Not Available For QueryNew() And Why That Should Scare You
Posted: November 15, 2006 at 9:40 AM by Ben Nadel

What I just noticed though is that the column data types returned from a standard SQL query do not line up with the data types that are available fo... read more »

ColdFusion CFSwitch Tag, CFCase Order, And Performance
Posted: November 14, 2006 at 7:23 AM by Ben Nadel
Now, I am sure I will catch some flack for this performance test, but until someone actually gives me CONSTRUCTIVE criticism on performance testing, this is the only way I know how to do it. That said, I was chilling in my bed last night watching a Family Guy rerun when I started to think about ColdFusion frameworks. Nothing in particular, just ... read more »

Bravo To FireFox's Restore Session Feature
Posted: November 13, 2006 at 2:11 PM by Ben Nadel
An Adobe PDF just crashed my FireFox. I had about 12 windows/tabs open at the time. I was almost peeved (but managing to keep my cool). I then went to re-open FireFox 2.0 and was presented with the option restore my former session. Not having done this before I was not sure what would happen. To my most excellent suprise, all of my windows/tabs we... read more »

Using ColdFusion, HTML, And CSS To Stop Spam Form Submissions (Revisited)
Posted: November 10, 2006 at 2:39 PM by Ben Nadel
For anyone who has posted a comment on my blog recently, you know that I was using a random Math equation to stop automated spamming via form submission. It worked amazingly well; I have only gotten a few spam comments (maybe 5) over the past 6 months or something. Having had such success with that, I thought I would take that idea and make even b... read more »

Extending ColdFusion Components And Its Impact On Page Performance
Posted: November 8, 2006 at 2:31 PM by Ben Nadel
It was lunch time and I was curious as to how extending ColdFusion Components affects page processing time and performance. For those of you who don't know, you can "inherit" the functionality of one component by extending it and overriding functionality. Component instantiation has some overhead in ColdFusion so that leads me to think that using ... read more »
