1. Product Description

The VUGauge OCX Control is a Microsoft Windows 32-bit OCX custom 
control that appears to the end user as a VU Gauge similar to those 
used on audio/video equipment such as stereos, tuners, and amplifiers.

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

Being a 32-bit OLE control, the programmer can add the NED VUGauge 
Control into any 32-bit OCX container application, such as VC++ 4.x,
VB 4.0 (32-bit), Access 95 or Delphi 2.0.

Use of the VUGauge Control in a finished application requires the
VUGauge Control OCX (NVUGAG32.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 VUGauge 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.

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

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

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

2. Legal Information

The purchaser of the VUGauge 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 VUGauge Control OCX (NVUGAG32.OCX). It does 
not include distribution of the VUGAUGE.lic file, or the documentation 
that comes with the Control. 

The purchaser of the VUGauge Control may distribute the control OCX with
applications that are networked (multiple users accessing the OCX 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:

   NVUGAG32.ocx		(NED VUGauge OCX)
   VUGauge.TLB		(NED VUGauge Type Library)
   README.TXT 		(this file)
   REGISTER.EXE   	(Registration Program)
   PROJECT1.VBP         (Visual Basic 4.0 32-bit demo program)
   FORM1.FRM   

If you have downloaded the NVGAGB11.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 OCX4032.ZIP in the same area as
NVGAGB11.ZIP.  This files in this archive should be placed in the 
same directory as the above OCX files.

MFC40.DLL      (Required for OCX)
MSVCRT40.DLL   (Required for OCX)
OLEPRO32.DLL   (Required for OCX)

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 and DLL files, place all of the above files in 
the same directory and run the REGISTER.EXE file.

From Visual Basic 4.0, open the PROJECT1.VBP file.

If you have Microsoft Access 95, start it and create a form or report.
From the Edit menu, choose Insert Object, and check the Custom Control
radio button. Choose the NED VUGauge control to insert it into the form or
report.
