SS, I need to ask about something that's puzzling me. Because you use what's below in your code, I tried to find some references to it (IEnumerator, IEnumerable) Here's the first thing I found. I tried searching through your code, but found 'none' of this.

First, we need to define a class to implement IEnumerable. Here's a start ...

Public Class Parties
Implements IEnumerator, IEnumerable

Public Function GetEnumerator() _
As IEnumerator _
Implements IEnumerable.GetEnumerator
Return CType(Me, IEnumerator)
End Function

This satisfies the requirement of IEnumerable because it implements GetEnumerator. How does it do that? It simply uses the CType operator to change the class itself into an IEnumerator and returns it.
Would you mind filling in some blanks? On the first sentence of the quote, it says to first create a class, but I saw none of that in your code. Of course it must be because you don't 'have to'.

Can you help me put these pieces together?

thanks
