Hi:
It is possible to load some Business Objects into a DataSet? Some example about how to make it?
Regards;
Gus

The PersistenceManager has a property called DataSet which exposes all of the objects in the PersistenceManager Cache as a DataSet.

Therefore:
(1) Create a new PersistenceManager
(2) Read some objects into the PersistenceManager Cache
(3) Access the DataSet through the PM's DataSet property
 

EntityList<Order> orders = pPm.GetEntities<Order>();

DataSet ds = pPm.DataSet;

Many thanks David:
BTW, it is possibly to have the XSD structure from this? I have a report tool (DataWindow.NET) which can extract data from the DataSet, but it requires the *.XSD file. My idea is to use IdeaBlade creating the Business Objects, and have some help from DataWindow.NET to create some reports.
 
Thanks in advance;
Gus

Look at the Intermediate tutorial on Reporting.  It has a solution for creating Crystal Reports.  Crystal has the same requirement for an XSD file that you have.  Use this solution (or more exactly, one of the projects from this solution) to get your XSD file.
