How do I Communicate Between Multiple LabVIEW Executables using Shared Variables?

Problem:
I have developed two executables and need to pass data between the two. How is this done using shared variables?

Solution:
In order to communicate between multiple executable applications using the shared variables it is important to use one LabVIEW Project. The project should contain all of the Build Specifications for each executable that is to be built.

In order to use shared variables they must be deployed, and when using them with executables it is important to explicitly do this as it cannot be automatically achieved as it normally can within the LabVIEW environment.

This is best achieved programmatically using VI Server and is fully documented in the following document:


How Do I Deploy Network Shared Variables From a Compiled Executable?


One common pitfall is including the Project Library that hosts the Shared Variable(s) within the Executable itself as this is the default destination. Whilst configuring the Build Specifications settings, remember to change the Libraries Destination to the Support Directory or another Pre-defined Directory.

 

An example project is attached to this document and can be used to demonstrate the behaviour. Remember to check through all of the Build Specification Settings in order to resolve any file paths to suit the local machine.
