I can tell you what I do. I create a typed Data set TruckDataSet for instance but the table name I created inside there is "Trucks" which matches the table name I am going to fill it with. All the fields I create in there are also a match for type and name as the actual columns in the table.

I put an instance on the form where I need to use the data. My DataAccess Layer in this older app has a general routine where I fill the dataSet passed into it.

So When I call it this way:
DataAccess data = DataAccess.Instance; // I am using a singleton pattern

data.GetAllTrucks(dsTrucks);

The dsTrucks is the name of the dataset I dropped on the form. This way I am passing in the actual dataset I need filled to the data access layer.

Now, I wouldn't do it this way necessarily now because I also have a business layer in the middle. But I think Kevin probably what you are seeing is possibly an issue with the names of the table you added to the DataSet. It needs to match your actual table I think as do the columns.

Try that and see if that is what you see. The layers you will see are a DataSet, a DataTable in there, Rows in the table, and each row will have columns.

See if any of that helps you out.
