I've updated my uShop Database Interfacing Document with an example of using ASP to populate a uShop Input Applet from an ODBC connected database. Be aware that it is not tested very well, but should give you a good idea. Knowledge of Visual Basic or VBScript is helpful.
The document is available either from me or from Microburst. I'd display it here, but the forum swallows up HTML tags.
If you are looking for Brian's updated notes on how he integrated uShop with a MySQL database using PHP, along with an ASP example of how to do this, just e-mail us at email@example.com and we'll send it out to you.
Thanks again :) Brian!
