How do I make a DLL with LabView 5.1.1?

[David Huggins]

I have a simple VI that polls a serial port and hands back a string (from a GPS receiver). I'd like to use my VI to feed data to a VC++ program. Can this be done?

As far as I know, this feature was first included in LV6. What you can do is to develop your application using 5.1 and ask somebody (with 6.x) to build the DLL for you.
Anyway, while you are only communicating with serial port, you can try to implement it using VC++ (to be easier, you may want to use the ActiveX control provided by Microsoft in Visual Studio).

Hope this helps

Thanks for the suggestion - we've recommended that the simple serial port routine be re-done in VC (or Delphi).

I've written this sort of thing before. It's pretty easy. Besides
being a programmer, I'm also a pilot, so I bought a Garmin 92 about 2
years ago for flying but then I got interested in how to read data out
of it so I wrote a little VB program and built the little serial cable
to do it.

Are you looking to do NMEA strings I assume? If all you need is a
simple little DLL to read a couple of NMEA text strings, send me an
email with the project details, etc. and maybe we can work a deal.

Garmin also has an SDK with it's own C++ classes that you can also use
for talking to it's GPS's. This isn't industry standard NMEA though.
I assume that other manufacturers probably have similar SDK's for
their own GPS's. What type of unit is it? Garmin, Magellan,
somet
hing else? What is your application? aviation?, marine?
something else?

I could write something directly in C, C++, or VB for you if you like.
I could also write it in LV 5.1.1 to 6.1 but it sounds like you
intend to work in VC++ anyways and I don't own my own LV license here
at home. I have written a lot of LabVIEW and a lot of serial apps
though in the past for various companies.
