sharing data between windows applications and labview

[Greg_Shipley]

Interested in sharing data between a .NET application and LV V9 or later application.

Data transfer would be simple and limited, but need to let my LV application know a 'green light' to proceed from the .NET application.  Both applications are on the same computer with either XP or WIN 7  could be 32 or 64 Bit.

I am open for ideas on how to achieve this goal.

I don't "speak" .NET so whenever I have to get my LV application to communicate with any non-LV application I first think of tcp.

The nice thing about TCP/IP is that it also works if the LabVIEW app is on one machine and the .NET app is on another.  Should be simple to build a Consumer/Producer system, where the Producer "sends" data to the Consumer via TCP.

Can you elaborate on the process to do this?  any examples on this site?

Thank you for your time.

LabVIEW comes with quite a lot of examples : Help >> Find examples... >> serach tab, look for TCP, really I think you will have enough there to get started with the LabVIEW side.

Are you also responsible for the .NET side?

[Greg_Shipley]

I am not writting the .NET stuff myself, but another guy here is so we have controll of it too.

Can someone recommend a safe or relatively safe port and IP that I can set my TCP to?

Goal here is to set these so most likely there will not be a conflict from something else.

Just pick one from the list : http://en.wikipedia.org/wiki/List_of_TCP_and_UDP_port_numbers

by the way 3369 is not in the list

LabVIEW does have the ability to connect to .NET assemblies. You can even register a .NET callback. The callback can run a subVI whenever it is invoked from the .NET program. It has been a couple of years since I had to do this, but it does work well.

The tools pallet -> Connectivity should have a .NET sub-pallet. You can set up your constructors, and register for call back events with the VIs here. There are examples you can look up as well.
