I am trying to generate multiple values onto my spreadsheet using PiArcVal. The timestamps I want to use (with PiArcVal) are generated (in another column) using PiCompDat. I'd like to avoid oversizing my PiArcVal ''array'', in order to avoid error messages when resizing the spreadsheet. It seems like PI SDK would be the solution. If that's the case, would someone be able to point me to a vba code that could solve my prob. If you know of a better way than VBA, please share.
