I am having problems with the code on page 154. I have entered it 3 times now and get the same result.

Customer.vb
Error lstCustomer, not declared.

Form.vb
Error SelectedCustomer, not declared.
Error DialogResult.Yes, replace 'DialogResult'with 'windows.Forms.DialogResults'

I have also started from scratch and re-entered all the code 3 times as well with the same result, I have checked the spelling so many times that I have

Customer.vb:
I don't see any reference needed for the 'lstCustomer' textbox code. It's only used in Form.vb. Are you sure you didn't misplace some codes?

Form.vb: [u]Error SelectedCustomer, not declared</u>
You seem to have forgotten to input this code inside Form.vb:

    Public ReadOnly Property SelectedCustomer() As Customer
        Get
            If lstCustomers.SelectedIndex <> -1 Then
                'Return lstCustomers.Items(lstCustomers.SelectedIndex)
                Return objCustomers(lstCustomers.SelectedIndex)
            End If
        End Get
    End Property


[u]DialogResult.Yes</u>

It happens to me all the times, I think VS 2005 won't let it as compared to whatever IDE's version the author is using.
All you have to do is to replace [u]DialogResult.Yes</u> with [u]Windows.Forms.DialogResult.Yes</u>

All,

The change from DialogResult.Yes to Windows.Forms.DialogResult.Yes happened between the last Community Technology Preview to the Final Release of the product. Please check the errata site for any last minute fixes to problems other readers may have come across.
