      Hello all,
      Is there any of you ever be able to push more than 30 VI in the exported VI list of VI server?
      I think I found a bug that is there since at least LabVIEW 2011.
      WAIT... don't answer the easy one... "export all VI"... if you were about to answer that, that means you are not developing a safe application.
      Thanks for any help.

      I read Darren's excellent article about creating healthy Dialog box (http://labviewartisan.blogspot.ca/2014/08/subvi-panels-as-modal-dialogs-how-to.html)
      I thought using a dynamic call and selecting the option Load and retain on first call would prevent loading the subVI in memory when loading but not running the caller VI. I created a super light project to test it but didn't get the expected behavior:
      - If I don't open the Caller, I don't see any VI in memory (except for the VI that reads the VIs in memory of course).
      - If I open the Caller, I see both the Static Callee and the Dynamic Callee, whereas I expected to see only the Static Callee.
      Did I misunderstand how that option works?

      I am running into an issue where my VI Server connection goes stale after a few hours.  Looking for a fast way to detect this and recover.
      Currently here is what I am doing:
      On first call, open the application reference and then open the VI reference.  Cache both of these.  Use the VI reference to call the remote VI. On subsequent calls, test the cached references to verify they are still valid and then call the remote VI. What appears to be happening is the references still appear to be valid in the caller but the connection is broken so the remote call fails.  Then I detect this and reopen the app and VI refs and can again call the remote VI.
      The issues are:
      The failing remote call takes a long time to timeout and I do not see how to control this timeout. The test of the refs does not actually test to see of the network connection is still good. The result is it takes a long time to recover and this is upsetting the user since it appears the system is locked up.
      What I need is a way to control the timeout of the 'call by reference' node or a way to quickly test the references to verify the network connection is still good before I attempt the remote call.
      Any ideas?
      thanks,
      -John

      Hi all,
      I almost never ask for help in LabVIEW... but for this one, I have no idea where to find a solution to my problem. I'm trying to exchange data between two executable. The way I was using in the past was VI server. But it seems that there is something in LabVIEW 2011 that is not working the same way than it was working with LabVIEW 8.6. I created in my project 3 VI. One publisher, one suscriber and one GET-SET variable that will be used to exchange data between my 2 .exe.
       
      What ever I'm trying to do, I cannot figure it ou how to read the data from the Get-Set. Even having the list of VI available in memory is not working. How can I access this VI by VI Server with an address at the input of the application reference?
       
      I'm preaty sure it has something to do with security... but what....
       
      Thanks for your help.
