commonly seen on stereo equipment.  The digital control displays
numeric data.

It can be used with any host programming environment or application
that supports 32-bit OCX controls.

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

same directory as the above OCX files.

MFC42.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
NLED.OCX

A 32-bit Microsoft Visual C++ example application is provided with 
the NED LED control. You must have the 32-bit version of Microsoft 
Visual C++ installed on your machine to run this demo.

The example application allows you to view both the LED 1 and LED 2 controls

that this is an unregistered version of the control does not appear in 
the release version.
