Please help. Thanks in advance.

Visit Jan Axelson's Parallel Port FAQ site:

http://www.lvr.com/jansfaq.htm

About a third of the way down the page you will see:

"...Visual Basic has no built-in way to access ports. A solution is to
use a DLL written in Delphi or C that enables you to use inp and out
routines in Visual-Basic programs. See http://www.lvr.com for inpout32
and other options..."

Good luck.

Also,

In that same URL from Jan, scroll down a little further and see the
response to the FAQ:

Q: My company has a product that connects to the parallel port. The
process of finding the port address via WIN95's properties window is
too much for some customers - we'd like the program to be able to find
the address itself without needing the customer to find and enter the
port address. How can we find a parallel port's address under software
control?

You might find the address - but using it is going to be a big time
problem
- under Win 95/8 I could run you up a device driver
I can't be bothered with NT/2K/XP device drivers

Under Win 9x an MSDOS box should do the trick

This is not really a problem. You can download IOocx from my homepage.
This is a wrapper for a device driver that works under all 32-bit versions
of Windows -- and is free.
