Hello, I would like to be able to import a csv file into my vb program, and have it do math on the numbers in the CSV. First, the csv can have between 1 column and 40 columns...First, how can I have it simply display the column headers (i.e. first row of the csv) in a listbox...secondly...how can I for example have it add up all of the rows for column 3...and give the average?
