demo/password to wrap around my software applications

i am looking for a package in vb 6.0, that would not allow my software to launch until a password was entered. I have found a version of my software that was not purchased, and was copied from another computer. i need to protect it here are my thoughts. if you have a better way explain. There should be two passwords, one that would made my software a demo version that would expire after the number of days that i select. the second would give them full access that does not expire. the password should be self generated by using the month and date that my software is installed.(example: june 10, 2002 the password would be 06061002 month month day last two digits of year. for a demo version month day month day 061006. The code should always be use the date which it is being installed to geterate the password i have a vb 6.0 app that is a .exe and one is a .mde your software should give me the ability to select which file i want to protect. ## Deliverables Complete and fully-functional working program(s) in executable form as well as complete source code of all work done.
