Is it possible to convert VI's from LabVIEW 5.1 to be usable in 8.2?

It sure would save a lot of time for us.

LabVIEW 8.2 can open LabVIEW 5.1 VIs.  So to "convert" them simply means open them and save or to mass compile them in 8.2.  However, note that you can not save from 8.2 to 5.1 so I would suggest making a backup first.

thanks

You may also find that you get quite a list of warnings when you upgrade. It is well worthwhile to select the "Save to File" option. That file will allow you to systematically work your way through all the things which have changed between versions. Some things, like the old style DAQ and serial functions have been replaced by DAQmx (or DAQmx Base) and VISA. Some of these changes will require some reprogramming because the interfaces are different.

You will also likely find that programming style and methods have changed such that rewriting portions or all of the program may be required desirable for future maintenance and to take advantage of new features such as the event structure. If the original program is still of value since the LV 5 days, making the upgrade maintainable will probably be time well spent.

Sorry, I still can't use my 5.1 file in 8.2,

thanks a lot !!

I was able to open it just fine in LV 8.6.1.  Why?  Because the file you posted is already saved in LV 8.2.

Why aren't you able to use it in LV 8.2?  Are you getting some kind of error message?  If so, what does it say?

sorry, I forget to paste the message,

the following is my problem, Thanks so much~

Error 7 occurred at Open File+.vi:Open File

Possible reason(s):

LabVIEW: File not found. The file might have been moved or deleted, or the file path might be incorrectly formatted for the operating system. For example, use \ as path separators on Windows, : on Mac OS, and / on Linux.

Verify that the path is correct using the command prompt or file explorer.

Well that error message says it all, does it. You are trying to open a file somewhere that is not there.

When you would look at the diagram you would see various Spreadsheet file functions that try to read a spreadsheet file from a hardwired path. You should make sure that all the files you try to read in there are actually present on your harddisk at the path location this diagram specifies.

If I may say so the wiring is horrendous and the application with its hardwired path constants very user unfriendly.

Well that is a completely different problem than saying you need to upgrade a LV 5.1 VI.
