What is the meaning of the following sentence in List 8-30.
using CustomerOrdersTableAdapters;
Is there a namespace named CustomerOrdersTableAdapters?
Appreciate your answers!

i am looking for this,too
but nobody answer it ,

If you've created the .xsd as instructed, there will be a namespace defined in the CustomerOrders.designer.vb (.cs) called CustomerOrdersTableAdapters. If it's not available via intellisense in your project, you've probably set up the project as a web application/project as opposed to a web site. You'll need to change the Build Action property of the CustomerOrders.designer.vb to "Compile" for intellisense to pick up the namespaces and classes defined in the designer file.
