I have added new columns to an existing MS Access 2010 Database that I have hooked into Visual Studio 2010. After updating the Database, the Data Source window and DataSet do not have the new columns. I looked at answers such as this: Visual Studio DataSet Designer Refresh Tables , but configuring the default query with "SELECT * FROM Reservations" (where it has been suggested that updating the query will cause the table to refresh) hasn't refreshed anything. And the built-in "Refresh" buttons on the Data Sources and Database Explorer windows haven't caught the updates yet (there is also a new table I would like to work with shortly).
How the heck do I (non-programatically) update my DataSet? I have custom bindings and do not want to have to manually re-create those by removing this data source and 're-adding' it. I would rather add some custom bindings for my new fields and keep on working away at this project!
Mine turns out to be close to a duplicate question... See this for the answer (and yes, it is as simple as going through the TableAdapter configuration under the DataSet designer.)

Also, see: http://msdn.microsoft.com/en-us/library/ms171902%28VS.80%29.aspx (How to edit TableAdapters)
... and, as I figured out after nearly losing my mind, I was actually one sub-folder off (meaning there were two copies of the database in my project folder). Projects -> MyProject -> db.accdb, and Projects -> MyProject -> MyProject -> db.accdb. If you're having this issue and querying is NOT working, look VERY closely at the path. VERY CLOSELY. :)
