Indeed it is. There are two ways:
- use the OCX included with Crystal. This method should be easy, but.... bugs in OCX handling
- do like we had to do. We linked to the Crystal print engine DLL (CRPE.DLL) using the ORA_FFI (foreign function interface). It gets a bit complicated as some of the handy functions supported by Crystal require passing structures as parameters. Since Forms can't do this for some really bizarre reason (poor architecture), we wrote a DLL in C that simple takes atomic datatyped parameters, builds structures, calls CRPE.DLL and returns the parameters to forms.
Its a kludge but it works. Received on Mon Jun 02 1997 - 00:00:00 CEST
