In the distant past, I've written a "next-previous" page selector, but I remember (again in the distant past) there was a section that listed pre-created apps that were available for free or pay. If one still exists, I can't find it.
I want to create this type of thing and I don't want to spend a lot of time doing it:
Does anyone know where code (free or priced) that would support this application exists?
Yes, you mean the ColdFusion Developer Exchange. It has been inactive for some years now.
You could find a solution, or at least a tip, in the Riaforge, Cflib or Github sites.
I think you are referring to the old Macromedia Exchange site, where you could buy/sell ColdFusion UDFs and CFX modules (as well as add-ons for other Macromedia/Adobe products). Sadly, that site is gone, and all of the content with it. You might look on CFLib.org or RiaForge.org for something free and open source.
