Hi, I am working on a project to operate on excel files using Lab Windows CVI 2009. Can anyone give the tutorial for the same?
Unfortunately I don't think such a tutorial does exist...
CVI comes with two instruments to interact with CVI: excel2000.fp and excelreport.fp; a comparison between them is given here by Martin.
Unless you want to use Excel to create reports, I would suggest you use the first one, which is the basic set of commands to interface the products.
The magic rule for using such instruments is: remember to close all objects and handles after you have finished using them! Failure to do so will result for sure in problems in subsequent access to Excel as an application or to some of its objects.
