  1. Hi all, So I'm working on making a certain vi a remote panel. However this vi is quite complex with a lot of property nodes events which makes remote panel connection can be a bit unreliable cross-site because of the amount of data being transferred. What i'm trying to do to solve this is use a secondary vi that grabs an image of the first vi's front panel at a given frequency so that any changes are seen with out having to send too much data back and forth between the server and client. Basically all we should see is the change in pixels. When a user clicks on the image on this secondary vi i would like to simulate a click on the first vi at the same co-ordinates which should give me full control. I would use the secondary vi as the remote panel instead. I'm guessing this is how remote desktop would work? I have looked into simulating mouse click events using the User32.dll and it works great > http://digital.ni.com/public.nsf/allkb/9BB3211F3469623649257360000E272C However my problem is that this vi may not be the top vi or may be transparent at times. So my question is, is there a way of simulating a mouse click on a specific vi even if its not on top or hidden? This idea may be too crazy to work and in that case any suggestions are welcome. Thanks in advance.
  2. Hi, I am currently developing a scope that displays live data from a test rig. The scope is accessible via remote panels. Tests normally run for many hours at a time, when monitoring the scope after several hours of running I notice that the data on the chart displayed via the remote panel is not in sync with what can be seen on the actual 'server' vi. The delay also seems to be getting bigger as time goes on. I also display the current data points in an indicator; however these seem to be in sync and 'current'. The scope is part of a built application and I am using labVIEW 2012 f3 to develop it. I know that there is an issue with synchronizing front panel appearances when using remote panels in built applications but I think I have got around that by re-applying panel changes when a new client connects. Also on every execution of the VI, I defer panel updates make all my updates to controls including the chart in question, force draw the chart and then re-enable panel updates. I would really appreciate if anyone that has experienced this sort of issue could share a possible solution/work around. Thanks in advance.
