Hi. The Palm developers' Knowledge Base has a pretty good white paper from March 2003, on copy-potection. Depending on how bullet-proof you want to make it, it can get pretty complicated. I guess it depends on the worth of your software.
By the way, on "unique ID" information, keep in mind that the Palm serial number is only available to software on PDAs that have FLASH ROM. The white paper can be downloaded as follows: http://kb.palmsource.com/ Under "Answer Type", select "Whitepaper". Under "Search Text", type "protection". Click on the "Search" button. In the resulting list, select "Platform Software Protection" Near the bottom of the resulting page are .sit (for MAC) and .zip (for PC) files that contain the white paper. It has some interesting ideas. Regards, Ed. -- For information on using the Palm Developer Forums, or to unsubscribe, please see http://www.palmos.com/dev/support/forums/
