A few years ago, I wrote a little utility for one of my clients who uses Crystal Reports XI to design reports inhouse. They wanted other people on the corporate intranet to be able to see and refresh the reports and if necessary, enter new parameters. Since they weren't designing reports, it didn't make sense to buy licenses for everyone and I was able to (very easily) come up with a viewer utility that did the trick. I finally wrote this article about it for ASPAlliance, as they have a great collection of articles (mostly written by Eric Landes).
