I try to use UDP (because I don't want to write a share_memory dll ..) to exchange datas betweend 2 VIs. Is it possible ? (so far, it doesn't work) Is there a better way to do that (and faster than write a shm in C) ? thank you !
Yes, that's no problem...If you search through the examples shipped with LabVIEW you'll fine VI's that exchange data via UDP and you can run them on the same machine.
Are the VIs in separate built applications, is that why you want to use a network protocol?
