Newbie question, sorry...

[Mr Fisto]

What's the best way of passing data from an LabVIEW application to a (C++
written) Windows application. The LabVIEW app would be running in the
background with the C++ prog with focus in the foreground. (There is no need
for data to go back the way from the C++ app to LabVIEW).

Any advice or links would be appreciated.

Barry.

Too vague a question. Is it a commercial C++ application or one you're
writing yourself? Is it an application that is to run continuously and
process messages from Labview as they become available, or something that
runs, gets all the data at the start and quits when it finishes?

I'm doing a similar thing right now. The best way I have come up with
is to set up a File Mapping Object that both programs can share. This
is basically a place in memory (that acts like a file) where both apps
can read from and write to. You can achieve this in LabVIEW by making
calls to Windows DLL's. Take a look at this site:
