### Using Report Viewers in applications

Viewing reports is not exclusive to web sites, you may find a need for client side applications that display reports on-screen to users. The Report Viewer for ActiveX and the Report Viewer for Java are fully functional components. These components can be added to applications written in Microsoft Visual Basic, Borland Delphi, Symantec Visual Cafe, and many other development environments that support ActiveX controls or Java Beans.

Note: The Report Viewer for Java is intended primarily for application development and is, therefore, not discussed in this chapter. Instead, this section concentrates on the Report Viewers intended for web site development that can be distributed using the Web Component Server or added using the Report Integration Controls.

Report Viewers are frequently used in application development when designing N-tier applications that use the Web Component Server and the RDC Automation Server as a middle tier, and the Report Viewer as part of the client user interface. For more information on using the ActiveX and Java Bean versions of the Report Viewers in application design refer to the Seagate Crystal Reports Technical Reference Guide.
