This tutorial describes how to use Microsoft Visual Studio 2005 to create a VB.NET client-server application from scratch. This application parses an ADT^A04 message, adds next of kin data as one or more NK1 segments, and then generates and displays the modified message.

	Note that this is a very simple example whose purpose is to show you how to use Chameleon in the VB.NET environment. In particular, this application does not use sockets to obtain messages from another application.

In this tutorial, you will:

• Create a simple VB.NET application to parse and generate HL7 messages;
• Create a VMD file containing a message definition;
• Generate stubcode that enables your application to interact with Chameleon;
• Import the Chameleon libraries into your application;
• Write code to obtain an HL7 message, obtain user input, and generate a modified message;
• Test the application you have just created.
