I am working with Labview V6.1 on a Win2000 platform with office 2000. I am trying to use the attached VI to open an existing excel workbook. I get an error 97 which is a null refnum error when I run. Any ideas on why this occurs?
You first need to open Excel with an Automation Open and then you pass the output of that to your workbooks property. See the shipping example called Write Table to XL.
