Default Webshop - Overload resolution failed

Many thanks for your truly inspiring book.
Unfortunately have one problem in Webshop application.
Following code generates "Overload resolution failed because no accessible 'New' accepts this number of arguments"
                Using myReader As SqlDataReader = _
                      myCommand.ExecuteReader(CommandBehavior.CloseConne ction)
                    While myReader.Read()
                        theProduct = New Product( _
                  myReader.GetInt32(myReader.GetOrdinal("ProductId") ), _
                  theProduct.Title = myReader.GetString(myReader.GetOrdinal("Title"))
                    End While

Any idea why?

Hi there,

Glad you like the book so much.

Did you make any changes to the code? This is supposed to work. The code you posted creates a new product by passing two arguments (the productId and the categoryId to the constructor. The Product class has this constructor:
Public Sub New(ByVal productId As Integer, ByVal theCategoryId As Integer)
  Me._id = productId
  Me._categoryId = theCategoryId
End Sub
So, the code you posted should work provided you haven't modified the Product class constructor in App_Code\BusinessLogic\Product.vb.

Hope this helps,
