About

FPOnGuard is port of Turbo Power OnGuard. OnGuard is a library to create demo versions of your Borland Delphi & Kylix & Free Pascal+Lazarus applications. Create demo versions that are time-limited, feature-limited, limited to a certain number of uses, or limited to a certain # of concurrent network users. You could also protect executable file from modification either by hacker or malware. It works for Windows and Linux also. Check it, it is really a cool thing!

This is a source-only release. It includes package for Lazarus 0.9.16 official installer (and should run fine on later versions too).

The download contains the component package for Lazarus + documentation (pdf and hlp file) and probably all original examples ported to Lazarus.

This component is now designed for cross-platform applications (Windows and Linux-like).Pure Object Pascal. However some parts are heavy system dependant.

TODO

• Test network usage code (NAF file is not locked?)
• Better machine ID (based on CPU (mostly unavailable) and HDD physical serial numbers and MAC address for example)
• Merge it with HASP USB keys support and others (plugin system?)
