shut down access after 30 day trial
How can I shutdown a database after a 30 day trial period. A vb code to pop
up a form to advise user of 30 day trial expiration. I can configure the form to ask user to continue and go to website or close and exit database but I need the vb code to time 30 days. Thanks for any help Dave J |

Tools available from sites such as sysinternals.com can crack any method you use to store a future date anywhere on a system such as in the registry or a file. Unless it's encrypted. But even then if you delete the date from wherever it's stored your app may think it's just installed. Thus I prefer to limit the number of records in one key table such as 5 units or 50 volunteers but allow unlimited access for everything else. Once I get paid then I email them an encrypted file containing the number of records they are licensed for as well as their company name which goes on the bottom of every page of every report and frequently used forms.
