The SportsPro sample application can be downloaded here on Progress Community, from the "Download 11.0 Documentation Example Procedure and Sample Files" page at community.progress.com/.../1162.download-11-0-documentation-example-procedure-and-sample-files.aspx . There are two files attached to this page. The SportsPro sample is in OpenEdge_11.0_Samples.zip, although you may find some of the examples in the other file useful as well. Although the page is marked "11.0", the SportsPro application and most of the other code will work with other OpenEdge versions. Good luck!
