I want to make some changes in my book after it has been published

Question

I think I have been quite clear with my intentions with the name of my thread:)
My books has been published, but I want to add some screencaptures to it. I have the screencaptures, but will I have to wait a few days while Apple checks my updated package, or will they just publish the captures without kepping the book from distribution during their check?

Answer 1

You don't tell it to read specific lines. You pick out specific columns. Based on your input file one simple way to do this is to use the Read From Spreadsheet File VI to read in your source files. Read the files as string rather than numeric. Chop off the first 15 or 16 lines (up to the start of tabular data) and convert the rest using the Numeric -> String functions to get a 2D array of numbers. You can display the resultant 2D array on the front panel and provide controls (e.g., an array of Booleans) to select which columns to keep. The lines you chopped off at the beginning can be reconstituted into your new header (a 1D array of strings, where each element is a line of your header). You can then use the Write to Spreadsheet File VI to write out your header (feed it the 1D array of strings which are your header lines), and then the new 2D array that constists of only the columns you want.
