ColdFusion UDF Library
December 16th, 2008
Part of being a good developer is the act of working smarter and not harder. And there is no better way to accomplish this than through code reuse. Adding your own Extension Library to ColdFusion is a direct and powerful way to increase the speed and consistency of your development.
These UDFs are available royalty free and you can either pull the function you need directly from here and place it in your code, or you can download the entire Extension Library and have all these functions available as if they were built directly into ColdFusion.
If you find this library useful, take a moment to contribute one of your own functions. Because working together we can make all of our professional lives as ColdFusion developers just a bit easier.

| numberToIp Converts a number to an IP Address (opposite of ipToNumber) |
| queryArray Copies the specified column of a query into an array |
| queryConcat Add two or more queries together. |
| Capitalize Converts a string to Proper Case Formatting |
| htmlEncode Encodes HTML (similar to: htmlEditFormat) |
