Retrieve E-Mail Through POP3?

I found these tutorials and codes regarding 'Retrieve E-Mail Through POP3' on an e-book entitled 'Microsoft Visual Basic .NET Programmer's Cookbook'. I understand what each functions/codes are but how do i design the GUI/interface to fit the codes?You want to retrieve messages from a POP3 mail server.Solution. Create a dedicated class that sends POP3 commands over a TCP connection.

POP3 is a common e-mail protocol used to download messages from a mail server. POP3, like many Internet protocols, defines a small set of commands that are sent as simple ASCII-encoded messages over a TCP connection (typically on port 110).Here's a listing of a typical POP3 dialogue, starting immediately after the client makes a TCP connection:

Server sends:+OK <22689.1039100760@mail.prosetech.com>
Client sends:USER <UserName>
Server sends:+OK[code]....

To add this functionality to your .NET applications, you can create a Pop3Client class that encapsulates all the logic for communicating with a POP3 server. Your application can then retrieve information about messages using the Pop3Client class. We'll explore this class piece by piece in this recipe. To see the complete code, download the recipes for this chapter in this book's sample files.

The first step is to define a basic skeleton for the Pop3Client class. It should store a TcpClient instance as a member variable, which will be used to send all network messages. You can also add generic Send and ReceiveResponse messages, which translate data from binary form into the ASCII encoding used for POP3 communication.
