I would like to receive some orientations about developing a system to distribute (sell) to clients, using some kind a
mechanism to prevent ilegal copies. I think about using a hard copy protection like a USB pen drive, because there will be
only a few copies.
Nowadays the system is a Excel workbook with VBA code and forms, plus OWC 11 sheets (placed inside forms).
How are the simplest, fastest and secure (against copies and reading VBA code) ways to achieve a selling product? (Visual
Basic, Visual Basic with VSTO, Visual Basic calling OWC 11, etc)
Thanks in advance,
