ActiveReports allows you to embed script in reports so that code becomes portable when you save a report layout to XML-based RPX format. This characteristic allows the options of stand-alone reporting and web reporting without the need to distribute related .vb or .cs files. By embedding script when the report is saved as an RPX file, it can later by loaded, run and displayed directly to the viewer control without using the designer. Script can also be used in conjunction with RPX files to allow distributed reports to be updated without recompiling the Visual Studio project.
