A DataSet can be Typed or Untyped. The difference between the two lies in the fact that a Typed DataSet has a schema and an Untyped DataSet does not have one. It should be noted that the Typed Datasets have more support in Visual studio. A typed dataset gives us easier access to the contents of the table through strongly typed programming that uses information from the underlying data schema. A typed DataSet has a reference to an XML schema file:
Dim s As String
s = dsCustomersOrders1.Customers(0).CustomerID |
In contrast, if we are working with an untyped DataSet, the equivalent code looks like this:
Dim s As String
s = CType(dsCustomersOrders1.Tables("Customers").Rows(0).Item("CustomerID"), String) |
As the syntax is much simpler and more practical, using typed Datasets is much more handy.
