launching a new app

HELP!-Possibly somebody can help me. I've written a foodservice program in filemaker pro and am looking to build an app written in VB that can open and protect the filemaker program with a 15 day trial offer and then allow the client to use a password (supplied by me when he pays for the program) to access the filemaker program after the 15 days have expired. The filemaker program has a runtime engine installed and everytime I have tried to build a script for a 15 day password in filemaker, the runtime installation starts the clock, and we will have to supply the password for the client to get in for the first time-in essence-we will be giving the program away for free. If anybody has any suggestions it would help us get our business of the ground as we have recieved good reports from foodservice industry pros (chef, etc.) about the validity of the program.
Thanx & Regards,

Hi,
Use the Shell command from VB to launch the Filemaker pro app from vb. Also you can buy a 3rd party DLL called AppExpire (available for $30) to control trial version. With this you can also have this program expired after certain date (say 1yr form date of installation or version numbers).
Demo copy of appexpire is available at www.download.com
All these values will be stored in the registry in a Hex format and prople cannot erase it unless they format the hard disk.
Guess this has to be used with VB only as FileMaker pro does not support Activex controls.
