I am currently working on an old Visual Basic 4.0 (16-bit) which uses Crystal reports version 4.5.
The project uses a module created by Crystal to access a DLL called CRPE.DLL
The module is basically a set of API calls to the CRPE.DLL file that allow you to access and print Crystal reports.

I need to upgrade to Visual Basic 6.0 SP4. The problem is that the API calls knowlonger seem to work when I upgrade the project to VB6.
I understand that I may have to upgrade to a version of Crystal that supports the newer Object models.
However I would like to avoid having to convert all the API calls to work with the newer object model (because I'm lazy and have a deadline)

Does anyone know why calls to the 16bit dll CRPE.DLL knowlonger work?
