While working on a project last night, I had to do some image resizing on user upload, ie a user uploads his picture and the system had to keep the original and resize the image to 2 other sizes as well and save them on-disk. With ColdFusion, this surely sounds just a few lines of […]
I stumbled across YQL today and although I had heard about it in the past, today was the first time, I actually sat down and read the documentation and went through some of the example apps. I am amazed at how powerful it is and am just imagining the wonderful applications that can be built […]
I came across a requirement today, where I had to sort a XML file by one of the attributes in one of its child nodes. I did some searching and came across these excellent posts by Ben Nadel. Obviously, that gave me some headstart and it was clear that XSLT was the way to go. […]
I was setting up a new Project in Flex Builder with Application Server Type as ‘ColdFusion’. I had the default values in the Flex Builder wizard. But the Wizard wont let me go past the second screen. I kept getting this error :- Invalid root. The WEB-INF/flex folder must contain either flex-config.xml or services-config.xml. And […]
