1. Product Description

The NED Gauge OCX Control is a Microsoft Windows OLE custom control
that presents a gauge control similar to those seen on the industrial
process control equipment.

This control is compatible with Windows '95. and Windows NT.

Being a 32-bit OLE control, the programmer can add the NEDGauge Control 
into any 32-bit OCX container application, such as Visual C++,
Visual Basic (32-bit), MS Access or Delphi.

Use of the NED Gauge Control in a finished application requires the
NED Gauge Control OCX (NGauge32.OCX) to be installed with the application.

There are properties available that allow the programmer to control
the behavior and appearance of the Control. The NEDGauge can appear
in four different orientations. Colors of various parts of the control
can be adjusted, and there are 3D properties that let you specify such
things as borders and bevels.

A High and Low limit can be set, which will cause an event to be sent
to your application when either condition occurs.

The range of the NEDGauge can be set to any range with low and high values
varying from 0 to 32767.


-------------------------------------------------------------------

2. Legal Information

The purchaser of the NEDGauge Control is allowed to use it and
distribute it in applications without paying any royalty, and without
printing or displaying a copyright notice for the control. This only
includes distribution of the NED Gauge Control OCX (NGauge32.OCX). It does 
not include distribution of the NEDGauge.lic file, or the documentation 
that comes with the Control. 

The purchaser of the NEDGauge Control may distribute the control with
applications that are networked (multiple users accessing the DLL from
a file server) without paying any license fees to Northeast Data Corp.


-------------------------------------------------------------------

3. Installation

Create a temp directory on your hard disk and copy all files from
the distribution disk to the directory. These files include:


   NGauge32.OCX		(NEDGauge OCX)
   README.TXT 		(this file)
   PROJECT1.VBP         (Visual Basic 32-bit demo program)
   FORM1.FRM   

If you have downloaded the NGAGVB12.ZIP file, use PKUNZIP to extract the 
files into the temp directory.

The files listed below are required to use the OCX and demo in this
archive.  This files can be found in OCX5032.ZIP in the same area as
NGAGVB12.ZIP.  This files in this archive should be placed in the 
same directory as the above OCX files.

MFC42.DLL    (Required for OCX)
MSVCRT.DLL   (Required for OCX)
OLEPRO32.DLL (Required for OCX)
OLEAUT32.DLL (Required for OCX)
REGSVR32.EXE (Control registration utility)

If you already have these files on your system, they are probably 
located in the System or System32 directory.  If this is the case,
you probably do not need to download these files again.  

To register the OCX, place all of the above files in the System(32)
directory and run the REGSVR32 on the following files:

MFC42.DLL
OLEPRO32.DLL
NGauge32.OCX

From Visual Basic, open the PROJECT1.VBP file.

If you have Microsoft Access, start it and create a form or report.
From the Edit menu, choose Insert Object, and check the Custom Control
radio button. Choose the NEDGauge control to insert it into the form or
report.
