Distributing Crystal Report Engine Applications
Seagate Crystal Reports comes with a royalty-free runtime license for any application that uses the Crystal Report Engine through any of the methods described in this chapter. When distributing a Crystal Report Engine application, you must also distribute several runtime files required by the Crystal Report Engine. These files are listed in the Runtime File Requirements online Help. Be sure to carefully examine this Help file and distribute the appropriate runtime files with your application. All runtime files are included under the runtime license agreement unless otherwise stated.
Additional Sources of Information
In addition to the information provided in this chapter, you will find a wide-variety of developer topics in Developer’s online Help. Many of these topics contain sample code in C, Visual dBASE, Delphi, and Visual Basic that you can copy directly into your application. For a list of all developer topics, see Developer’s online Help.
If you are working with the Crystal Report Engine API in Visual Basic, refer to Using the Crystal Report Engine API in Visual Basic, Page 104, for information specific to Visual Basic. Delphi programmers can find information specific to using the Crystal Report Engine API with Delphi under Seagate Crystal Visual Component Library, Page 193.
