Programming with the Report Engine Object Model

The object model is the main entry point to the Crystal Reports engine for desktop applications. As mentioned earlier, it is based on COM and can be used from any COM-compliant development environment. Although the main library's filename is craxdrt.dll, the more important thing to know is that it shows up in the Project References dialog as Crystal Reports ActiveX Designer Runtime Library 10.0, as shown in Figure 30.3. After a reference is added to this library, a new set of objects will be available to you. These objects are contained in a library called CRAXDRT. To avoid name collisions, it's probably a good idea to fully qualify all object declarations with the CRAXDRT name, for example, Dim Param As CRAXDRT.ParameterField.
