The Crystal Report Engine 8 Object Library exposes the Report Engine API, first introduced in Crystal 5.  It will allow you to do most anything you want, from designing a report in code to printing one, but is geared more towards C instead of VB or Delphi

The CRDatasource Type library contains the Crystal Data Objects which allow a VB programmer to model data at design time using arrays when the real data isn't available.

The ActiveX Designer Design time library is what allows you to access the designer from the VB IDE so you can design your reports without the need for the standalone CRW Designer.

Crystal Report 8 Library exposes some properties/methods for controlling the report designer if you choose to pay the licensing fees and let users of your apps design their own reports.

For any new work you'll be doing, use the RDC (introduced in CRW 7) and the Crystal Report Viewer.  Add these to your VB projects by going to the Project->References menu and selecting "Crystal Report Viewer Control" and "Crystal Report x ActiveX Designer Run Time Library"

If you are new to CRW and haven't found it yet, there is a developer's help file on your system at "C:\Program Files\Seagate Software\Crystal Reports\Developer Files\Help" - put a link to it somewhere
