Database Connection

Experts, just a quick question. I am about to start work on an application and was just wondering about good practices. I will use an Access database with my application. The question I have with regards to the connection should I open the connection in a module and make it public so that all forms and classes can access it and then close the connection when the application closes? Or should I create the connection within each form or class and then close the connection with the form is closed or the class is disposed of? Or does it make any difference.

From the .Net side, you should normally only keep the connection open while you are accessing it and close it when that operation is complete. Databases only have a limited number of connections and each query would use it's own connection and you would quickly no longer be able to connect from the application.

See this about ADO.net connections, they use an Access database. It should help you. Please don't be offended by the title, it was simply a good read.

But if you are building an application that is going to get much use or needs to grow in the future, I would look at using a database and not Access. It is good for single user, low data type apps, but anything that needs to hold more than 1 or 2GB needs to be somewhere else (MS SQL, MY SQL, Oracle, etc.)
