Last week I presented Visual Basic 2010 to 24 defense contract programmers who are using Visual Basic 2005.
They were very pleased by what they saw and I can see why.
In comparing 2005 with 2010 with the group it made me realize just how much Visual Basic.Net has improved. Looking back at 2005 was like taking a trip to the past.

LINQ to SQL translates LINQ queries to SQL for execution on a database. The results are strongly typed IEnumerable . Because these objects are ordinary common language runtime (CLR) objects, ordinary object data binding can be used to display the results. On the other hand, sorting and change operations (inserts, updates, and deletes) require additional steps.
For example, to provide a DataSource for a DataGridView that can be sorted using the DataGridView's b ... [ read more ]
