Had a great success with Network Published Shared Variables from the get-go. Used them on a large project sharing data between multiple devices on the network - worked great. Until one day (yesterday), when they stopped. No change in the code, the same base was running for 4 years on multiple systems (NI-9042 cRIO + NI-9147 eRIO). Yesterday, loaded the code on a brand new cRIO and ooh-la-la - surprise. No more data sharing. Only on a new platform. Loaded the same code on the old one - everything works. Modified the code to make data sharing more transparent for troubleshooting. No, there is no data coming to the consumers. Not sure though whether it is writing to the shared variable or reading from it but the fact is no more data. At this point I am totally baffled to what could possibly happen. Checked the drivers - the Network Variable Engine 17.0 is installed. Although, I am not sure how to check if it is running. I tried to use Linux tools in CLI but didn't see any process name resembling the Network Variables Engine. I wonder if anybody had similar experience or can suggest where to look? Maybe I am overlooking some weird settings somewhere? Like blocked ports or network registration... However, I couldn't find anything, no matter how hard I looked. Any help would be greatly appreciated! Thanks.

Hi Everyone, I am trying to play the video in reverse decrementing the frame number in IMAQ Read Frame function. Its working but the result is very choppy as every frame takes significant time to load, but when I just increment the frame number and play the video forward, its executing without any problem. I have attached the VI and info regarding the video, could you guys please let me know why I am having problem when I am trying to display the video in the reverse order. Playing AVI file.vi

Hello, When I delete virtual folder in me project this results in a LabVIEW crash. This happens in windows 10 and in windows 7, even if I have a project with only empty virtual folders and I start deleting them. Are there other people where this is happening too?

Hey guys! So, I've installed LabVIEW 2017 and I'm starting to play around with it. Malleable VIs are cool! (No more giant OpenG toolkits where there are 10 instances of the same VI for multiple datatypes.) Another cool thing that I've observed is that the example "sort 2D Array" function can support a scalar and an array input for index. Upon further digging, there appears to be an interesting disable structure that intelligently selects the upstream input that yields non-broken code. Does anyone have more information about this structure? Is this related to the experimental structure that Hooovah talked about in his Xnodes presentation at NI week? I'm just curious if this is stable... and if I can start using it... and it there is any documentation on it that would tell me how to use it.
