Standard mini-demos are not capable of demonstrating how well each WPCubed component works when combined with its siblings. Here you can download sample project which demonstrates in details the various facets of our VCL components WPTools with WPReporter, WPViewPDF and wPDF. This multi-demo – WPCubed “Calculus” is the core of a customer management application with the ability to write invoices which are created as PDFs and consequently saved to database in this form. It only uses a minimum set of database tables and database fields to demonstrate how the components can work together.

The demo integrates document management – an invoice can be saved as PDF to a database, but it does not implement versioning. In a “real” application it should not be possible to change an invoice after it was sent out.  Since WPViewPDF “demo” was used, the printout of the PDF includes a demo watermark.
