VS2008 Crystal Reports Database Connection from Web.config

I have an ASP.NET application I'm developing. In it is a CR report. When I first wrote the report, I had it hard coded to point to my development server (using MSSQL with Windows integrated login). So, when I moved my app to the production server, it of course failed. I have been searching for an answer on how to connect it to DB listed in the Web.config, but haven't had any luck.

I saw one suggestion that I create a dataset in my project and tie in to that, but now it seems I can't use a parameter to filter the records. I did see one other suggestion on how you can change the DB source on the fly, but that was designed for those who want to change the DB in mid session, rather than dependent on the machine, and seemed overkill.

Does anyone have a nice simple solution? I have been working on this problem for way too long and feel that I'm about to shoot my computer (that will teach it a lesson). :-(
