spreadsheet

[Ed747]

Hello all

My computer cracked last time and I was able to rescue the NI files but there is a vi program that is looking for a spreadsheet.vi file. In the block diagram there is a ? sign and there is 1 magenta links to it and coming out one TF (green) box and % type sign. Where can I find this file? By the way The old hard drive is brocken and can't recover anyfiles from there.

Any help I would really appreciate it

The newest LabView I've used is version 3.1, but I think it's safe to say that spreadsheet.vi is a custom sub-VI rather than one of the standard analysis functions. Apparently it takes in a data array and crunches it down to a number and a Boolean. If you are fortunate, you may have spreadsheet.vi stored in the wrong folder or LabView doesn't have the right path for it. This can be fixed by either moving it to the right place or changing the properties referring to it in the main VI. Otherwise, if the author of the main program is not available, somebody gets the fun of trying to reverse engineer the main program and recreating the missing VI.

If this vi was included in a VI library that was lost when the drive failed, there may be other VIs that are missing pieces stored in that library. This situation is a reminder for everyone to include LabView files in the hard drive backup routine...

I agree that its probably a custom sub-vi. Its also possible that it might be an example vi shipped with labview. Its worth adding a vi search path to the examples folder.

Go to menu Options -> Select Paths -> Select VI Search Path and uncheck use default. Add the path to the examples folder.
