I am working on creating a sample Dataset with a couple of DataTables and some columns, using VS 2005 Dataset Desinger.

1. I added a Dataset to my project, DataSet1. So now I have a tab DataSet1.xsd in my solution.
2. I click on Toolbox -> Datasets, then click on DataTable. Then click in the "designer" area. A table DataTable1 appears. I can add several columns, no problem.
3. I repeat steps 2 a couple of time, adding DataTable2, DataTable3.

Question 1.
DataTable1, DataTable2, DataTable3 do not appear in my solution. How can I visually see that those tables belong to the Dataset DataSet1?

Question 2. When I open Database Expert in the Crystal Report of this solution, I see ADO.NET Dataset MyProject.DataSet1 with one table DataTable1. Where are the DataTable2 and 3?

Question 3.
In the CODE magazine article by Kevin Goff (on using Crystal Report with .NET) there is a picture of two tables where the tables show the names of the columns and the DataType of each column.
In my designer I only see name of the column. How do I make it show the Type too?

Thank you in advance for your help.
