Could someone clarify 'why' this worked out the way it did...

I completed a hands-on project from a textbook I'm reading.

The purpose was to create a composite user control (containing identifying labels and text boxes) referencing a "Person" structure.

Now, it 'worked' okay, but only after I made one minor change to my container form:

The book's solution calls for the form's OK button procedure to be:

    Private Sub btnOK_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnOK.Click
        'Retrieve the entered information
        Dim perPerson As Person

        perPerson = NameEntry.PersonText
        MessageBox.Show( _
        perPerson.id & ControlChars.NewLine & _
        perPerson.Name & ControlChars.NewLine & _
        perPerson.address & ControlChars.NewLine & _
        perPerson.city & ", " & perPerson.state & _
        " " & perPerson.zip, "Display Entered Information")
    End Sub

Where mine ended up 'having' to be:

   Dim perPerson as Person.Person

How come?

The first Person is the namespace, which would suggest that the Person class is in a different namespace to the Form.

Is there any additional namespace defined for the Person class other than the root namespace ?

i.e.

Anything like:

    Namespace Person
        Public Class Person
        End Class
    End Namespace

I searched the entire projects for "names" (namespace) and it came up empty.
I don't know.  This was supposed to be a 'learn how to do it before you actually do' example.
I'm just a bit discouraged that the meat of the text never dealt with this issue and then right there at the last example, it was dropped in there.  <sigh>
I've given up on it and moved on to my actual assignment.  Thanx anyway - points are yours for the attempt.
