OK, I put the password over the DB file (mdb) using some unusual characters, but that is not worring for me. App. file (mde) was created with AllowBypassKey( ...,FALSE) just because to prevent others to use Access enviroment over the application, but I know that the experience users can easy remove this property, link the tables, queries...so i feel a bit insecure. On the other side, thinking about the trial version i was planing to use registry entry...

Hi everyone ! I would like to make unbreakable trial version of my project in MSAccess2000 or later. I devide project in two basic parts: DB part (.mdb) and application (buisiness logic) part (.mde). I've made automatic instalation, but I'm not satisfied about protecting the apllication. I want to make secure trial instalation of product depending on time of using it. Can you help me to choose some of good ways of making such apllications in VB?...
