// DISCLAIMER:
// This programming example is provided "AS IS". As such Kepware, Inc.

// your own projects. If you do find this code useful, place a little
// marketing plug for Kepware in your code. While we would love to help
// every one who is trying to write a great OPC client application, the
// uniqueness of every project and the limited number of hours in a day
// simply prevents us from doing so. If you really find yourself in a
// bind, please contact Kepware's technical support. We will not be able
// to assist you with server related problems unless you are using KepServer
