mainwnd.h

PC客户和opc通信的源代码

// **************************************************************************
// mainwnd.h
//
// Description:
//	Defines a CFrameWnd derived class.  This the main window of our GUI which
//	contains the group view, item view, and event view panes - the view parts
//	of our MFC SDI document/view architecture.
//
// DISCLAIMER:
//	This programming example is provided "AS IS".  As such Kepware, Inc.
//	makes no claims to the worthiness of the code and does not warranty
//	the code to be error free.  It is provided freely and can be used in
//	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
//	or KepServerEx.
