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? Thank you...

What about your current structure do you feel is insecure?

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 during instalation, and making ordinary text file witch I'll be station somewhere on the file system with "uncognizab le" content indicating the trial period of using application. Those information I can control through the application, but, you know, those informations can be descover...What do you think about this ? ...and I would like to implement some stronger and wiser protection, and control the trial period at the instalation instant from inside of application. Do you have any suggest? Best wishes and thank you...

This is really a problem. You cannot prevent an advanced user from directly access the tables in the backend database, even if it is password protected (by importing linked tables from the frontend database). Not mentioning that MSAccess database password can be easily discovered with some applications ...
So If you find any solution for that pls let us know :)

Hi there,
I have get a book wich have a free trial version of IBM DB2 (7.2) wich I

time with a message in a box that specify this will take few time.

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
Here is my compilation command:
