Overriding a UDF in ColdFusion

Fri, 05 Jun 2009 10:03:00 -0500

This morning my friend Don asked me the question of "I have a UDF defined in Application.cfc. Is there a way to override that with a UDF of same name in another template?"

Sat, 09 May 2009 11:06:00 -0500

I have released a little tag that I have used for a couple of years now that persists the session information to the database. It has worked like a charm and has little impact on performance. SessionSwap

cf_googleMap enters into 1.5 beta 2

Wed, 13 Aug 2008 22:08:00 -0500

I am happy to announce that cf_googleMap has been released into beta 2. The latest version can be downloaded here. There are still a few bugs left before I can call this one a full release candidate. Overall this has been a huge release and there are so many new features that I have to test the heck out of it.

Decrypting PGP files with GnuPG and ColdFusion

Mon, 04 Aug 2008 14:57:00 -0500

A few years ago I came up with a monster hack of automating the decryption of a PGP file with GnuPG. There are a bunch of limitations with CFEXECUTE so I turned to a VBS file and ADO to get the job done. The monster hack ran fine for a long time and just recently died when we upgraded to MSSQL 2005. After I was not able to fix the ADO connection properly I turned to some different solutions. What ended up working perfectly was using Java to execute a command line directly and just completely bypassing the CFEXECUTE. I stumbled upon System Command from Kevan Stannard and it worked perfectly. The same command line calls that I made to GnuPG now worked through CF using the System Command to do the execution. The trick to getting it to work is that GnuPG stores the PGP keys in relation to your user profile on the computer. So I ended up scripting out a batch file that added the keys into GnuPG, logging into the server as the same user that the ColdFusion service runs as and running the batch file to add the keys. After that the PGP decryption process has worked flawlessly.

In theory you could import the keys into the local system user but we already had a user for CF setup.

CF_GoogleMap 1.5 in Beta

Tue, 29 Jul 2008 21:13:00 -0500

After a lot of work I think cf_googleMap 1.5 is finally in a good solid beta state. If you are interested in giving it a whirl you can download it here.

CF_GoogleMap 1.4 Released

Tue, 10 Jun 2008 14:03:00 -0500

Well I have to say that I didn't get as much done in the 1.4 release that I would have liked to but I was able to make up enough progress yesterday that I wanted to go ahead and release it. Last minute yesterday I was asked to present the tag at the Denver ColdFusion users group and while I was waiting for my turn to present I was able to add in these features. (1) Added the showTraffic attribute to the cf_googleMap tag.
(2) Added the showLocalSearch attribute to the cf_googleMap tag.
(3) Added a language attribute to the cf_googleMap tag.
(4) Added the enableZoomScroll to the cf_googleMap tag and defaulted it to true so a use can use their scroll wheel to zoom in and out
(5) Added the enableGE to the cf_googleMap tag and defaulted it to false to enable the Google Earth view of the map.
I also added some MSSQL User Defined Functions in the download as well that will help calculate distances in your data access layer. The 1.5 version will be out shortly here. I figured out how I want to implement the point sets for various map levels and also figured out how to do the integrated driving directions without breaking the old way of doing driving directions.

What do you want in the next version of cf_GoogleMap

Sat, 12 May 2007 07:48:00 -0500

Sorry for the lack of updates. I've been concentrating getting a software product out the door and changing jobs as well. It is about time to start on the 1.4 version of the tag. Now is the time to voice your opinion on what you would like to see in the next version of the tag.

Goals for 2007

Wed, 21 Feb 2007 16:42:00 -0500

While be it late I wanted to share some of my goals for 2007. #1. Have at least 3 open source projects. Releasing cf_googleMap has take a lot of my time and it has been a learning experience to say the least. Dealing with other developers hacking away at your code, finding bugs and asking for feature requests is a bit scary. It really is the best form of peer review. I have some ideas on releasing some other projects around better error trapping and reporting, better debugger than the classic cfml debugging page. I am open to any other ideas as well. #2. Release a product myself and not through my employer I have been working on a product to release to the world for the past few months. I want to make money while I sleep! (More to come soon) #3. Write an article and have it published I have a decent start on some uses for the asynchronous event gateway. I just want to finish it up and submit it into the CFDJ. #4. Enter a contest I've seen many of the coding contests come and go and I never took any time to enter any of them. I doubt that I will win but I want to make an effort of going through the process. I've heard a lot of good things that you learn by going through some of these contests and I just want to put my hat into the ring.

cf_googleMap v.1.3.1 release

Wed, 07 Feb 2007 08:07:00 -0500

There are only a couple of new features in the 1.3.1 release. I wanted to release this ASAP as the 1.3 tag had some bugs in it that threw JavaScript errors

Added the option to view a overview map.
Added logic to not add the point to the map if the latitude or longitude are not numeric.
Fixed zooming issue where controls are not active until the point is clicked or the map is dragged.

You can view the details of the changes on the project page or download it on RIA Forge

IE not loding a custom 404 page

Mon, 29 Jan 2007 17:00:00 -0500

I ran into a interesting issue this morning where IE would not load a custom 404 page I had built instead it would just use the default "friendly" http error messages. After a decent amount of searching I found that if your 404 page is less than 512 bytes then IE uses its "friendly" error messages. I ended up just placing a HTML comment with a bunch of crap in there to get the page to load.

cf_googleMap v.1.3

Wed, 24 Jan 2007 06:17:00 -0500

There are a lot of items that went into the 1.3 release. I have been slammed at work and some remodeling at home so it has been hard to find time to wrap up this release. Once again I must thank Jeff Gladnick for some invaluable feedback and most importantly a base code for a better geocoding engine.

Changed the logic for the mainpoint attribute so it can be overwritten when a false value is passed.
Added documentation for to the mainpoint and how it defaults to true when there is 1 point on a map
Removed the default 1px blue border around the DIV container for the map and replaced it with a style attribute for the googlemap tag.
Added the show attribute to the cf_googleMapPoint tag
Added the GM_clearMap() JavaScript function
Changed the max characters for the driving directions from 40 to 255
Added example for using the geo.cfc Geocode
Renamed the Geocode function to GeocodeUS
Added a new Geocode function based off of code provided by Jeff Gladnick. This should provide a much more accurate geocoding including international addresses.
Added callJavaScript attribute to the cf_googleMapPoing tag

Presentation - ColdFusion on Apache

Mon, 22 Jan 2007 14:09:00 -0500

Would you like to remove the hypodermic needle of IIS from your local development or production systems and jump over to Apache but never knew where to start? About 2 years ago I started using a laptop and needed to work on multiple websites and the whole localhost development in IIS just did not cut it. We will be going over the following 1. How to configure Apache and ColdFusion. 2. Setup multiple websites 3. Point different Coldfusion instances to be used on different websites Please let me know if there is anything else that you would like to cover and I will see about adding it to the presentation. This meeting will be in person and via Breeze as I am still shoveling myself out of all this snow in Colorado. Edit: The meeting is tonight at UAT at 6:30pm MST Adobe Connect
