The VCL interfaces include a replication of our demo in Delphi and Builder projects. You can access these projects from where you installed ProEssentials or from the "Start" menu:
Start / All Programs / ProEssentials v9 / Delphi Example Project
Start / All Programs / ProEssentials v9 / Builder Example Project
Before checking out the example projects, be sure to try one of our Walk-Throughs.
