Reconfiguring Connection String in DataAdapter

I created an app in VS2005 where I had dragged oleDbDataAdapters onto some forms. Each oleDbDataAdapter is connected to the same database. I have the connectionString in my app.config file but do not know how to point the dataAdapters to that connectionString instead of the ones they are using. I've tried running the wizard again but it will not allow me to select the app.config connection string.

What is the answer here? I still want to be able to use the auto-generated Commands if I can.

Thanks,
