How to pass data from a C++ program to LV to plot the data real time?

[Molana]

Hello,
I am writing a C++ program in which I need to plot the data in real time. I would like to pass data from my C++ program to LabView in order to perfrom the plotting. I was wondering if this is possible. If so, how can it be done? .
Thank You

It's probably easiest to build a DLL from the LabVIEW code. You need either the professional version of LabVIEW or the add-on Application Builder in order to create DLLs.

I believe CIN also works for your application. If there is database there, like both you C++ and LV program can access DATABASE to store and retrieve data.

Hello,
Thank you.  I know how to create DLL' but once I've created the DLL, how should I work it from there?

There are several C++ examples and application notes here.
