When i build applications I always make an agent in my templates, with the following code:
@Prompt([Ok];”Version”;”LSK applikation R8.5.1 (01-11-2009).”)
Every time I release a new buikd for production, i change the text in the agent befor I deploy. Som of my applications has 20 or so databases within it. This way I can check if a database is running the version i want i to. If you have diffent versions running in production, it is also easy to tell your users to choose Actions, Version, and tell you what version they are running, if you have som helpdesk issues.
