Hi Robert,
I have not used the DANS Dataperfect library class. It only reads DataPerfect files, and only via panel access. You cannot get access to data through reports, so you need to process any of the returned data in your application. Using DataPerfect on a Linux Webserver with DOSEMU MSDOS emulator, or on a Windows server with Apache webserver works fine for me. You can read and write data, Have full access to the features of DataPerfect that are accessible via reports, which makes it incredibly powerful. DP Reports are the interface to the application. I have put up a number of posts before, and even completed samples, where you can just do a simple setup on a Windows PC. You can output reports in form of direct HTML pages, or as XML or JSON. I tend to use XML with either server side XSLT processing, or server side templating, but can also be used for AJAX. The first few steps with it can seem a little difficult, but once you have the idea, its pure DataPerfect skills from there on, with the advantage that with a little more non-Dataperfect effort you can do far more things than DataPerfect could ever dream of. The hardest thing though is decisions about hosting. Not many commercial webhosters will have the configuration needed to run it in a shared webhosting. You can easily use a dedicated or virtual server at a commercial webhoster however that gets expensive. The other choice is hosting it from your home or office using your own server, these days fast internet connections, routers with DMZ's, and that more people understand how to make it work make this a more attractive option than in the past. In Australia I have a commercial web hoster that will host DOSEMU on a shared Linux host. It costs me less than $200 a year, and includes SSH so I can run the applications in a terminal window. So even with it sitting on a server, which as you probably know, can be located anywhere in the world, you can still access it like a normal DP application. Another issue that you have to think about is the maintainability of DataPerfect as a web application. Ideally you want to be able to add reports etc by just creating reports offsite, and then uploading the new .STR, but if you use incrementing number fields in panel designs then you will cause problems, so you need to remove incrementing numbers and replace them with something else, I use Ralph Alvy's Recursive Numbering. Anyway, let me know if I can help.

Are the DVDs from the Huntington Beach conference still available, and what is the cost? Also, I / we would like to know more about using DP as a backend to a web site? I'd appreciate any help with this. Robert - Robert Pollard www.google.com/profiles/ecology2001 twitter.com/climatechange3 [email protected] 1.212.864.3156
