A5 V9 feature peek #55: Flexible connection strings

In older version of Alpha Five, when you built a grid or dialog component against either an ADO or AlphaDAO data source, and you specified the connection string using a named connection string, the named connection string was resolved at design time. In effect, the named connection string was nothing more than a shortcut for specifying a hard-coded connection string.

In Alpha Five Platinum, when you define a dialog or grid component using a named connection string, the connection string is resolved at runtime by looking up its value in the a5_application.a5i file, which is always automatically published when any file in your project is published to your server. This means that a connection string can actually be changed after the project has been published by editing the a5_application.a5i file.
