accessing "globals" from 2 different executables

[testpp]

For an application we need to access the same set of "globals" from 2 different executables.

How can this be done?

hi

can't be done (as far as i know). each executable has its own data space, so no memory or vis are shared between two executables (well, otherwise the behaviour of an app could change when other apps are opened). to share data between two apps i suggest to use dstp, tcp, udp or just a simple ini-file.

or: build a single application. the top level vi of the app calls both top level vis of your apps dynamically. then they use the same dataspace.

Hi,

if you want to exchange data in real time I'd suggest using some TCP communication. It's quite easy to implement. Saving to a file and reading from with the other application is fine if the data doesn't change to often, but you'd have to poll the file for changes or tell the other application some way (TCP again...). BTW, you might think about using queues (or similars) but they do just work inside one application as well.
