Beginner - Polymorphic Read from Spreadsheet File

[gborges]

Hi !

I have a problem here. I developed a VI using the Labview 8.2 but now, I have to downgrade the software to 8.0, and my VI stopped to work.

The problem is that the function Read from Spreadsheet File. I have to read a file that contains only strings, but I don't know how to configure it in Labview 8.0. I attached the code image in versions 8.0 and 8.20.

How can I solve it?

Thank you in advance!

Making the spreadsheets VIs polymorphic has been a request for a long time and it only happened in 8.2, so as you see it breaks if you need strings in 8. What you can do is double click the VI and read the (simple) instructions on the diagram for how to change it to work with strings. Note that once you do that you should save this copy under a different name and in a different location so that it doesn't overwrite the original.

To learn more about LabVIEW, I suggest you try searching this site and google for LabVIEW tutorials. Here, here, here and here are a few you can start with and here are some tutorial videos. You can also contact your local NI office and join one of their courses.
In addition, I suggest you read the LabVIEW style guide and the LabVIEW user manual (Help>>Search the LabVIEW Bookshelf).
