Just a little probleme with Labview 8.0 and Excel [URGENT]

[Deufos]

Hello

I made a VI who just read the A3 cell from an Excel file. I've got 3 errors and i don't know how to resolve it

If you can take a look to my VI, thank you.

I'm using labview 8.0

Hi Deufos,
see this example. I wrote it a long time ago, so it could be that it is not the best programming style, i´m sorry for that.

Hope it helps.

If you are talking about the VI errors. LabVIEW will give you basic descriptions of what's wrong.

1.  Variant to data has an unwired terminal (variant).  You must wire it up.
2.  Invoke node generally requires the reference to be wired.  In this case, the workbooks reference you get just to the left from the Excel Application.
3.  Your case structure has nothing wired to the selector (the ? symbol on the left hand side).  It is required to be wired.

Open the Example Finder (Help -> Find Examples), and search for examples on using charts and graphs.

Hi Deufos,

do you mean a cube?

You can use the "Picture Functions" vi´s.
