I've just tested it, and Split() does not honour quotation marks: it reads them in with the rest of the text. <br>So if a data item contained a comma, it would be seen as a delimiter :-(<br><br><div class="gmail_quote">

<p class="MsoNormal" style="border:none;padding:0cm"><span style="font-size:10.0pt">One of the more common uses of reading a text file is to read various values of a CSV (comma separated values) file, where individual items (think fields of a flat file database)
are read into an array for future processing. Visual Basic has a very nice easy way to do this using the Split function. Imagine that you have the above text file with the following data copied from this week’s Aria charts;</span></p>

<p class="MsoNormal"><span style="font-size:11.0pt;color:#1F497D">Thanks for that Mark. I have been using something similar with my students, particularly as the SAC I have written includes reading from a text file (A prototype

<p class="MsoNormal"><span style="font-size:11.0pt;color:#1F497D">One thing I was wondering though, does anyone have anything good on reading comma separated text files? All the programs I have gotten my students to create
read them a line at a time, but I would ideally like to see something like this line -

read into arrays. So I would have a “Name”, “Issue”, “Computer_Number”, “Room_Number”, “Priority” or something like that. I’m fine with the arrays, but how would I read it in word at a time (i.e. Between commas” rather than line at a time?</span></p>

<p class="MsoNormal"> </p>
<p class="MsoNormal">Hi, you paragons of pedagogy. I've been putting off teaching my kids how to read and write text data files in VB but having investigated today, it's not really more difficult than the days of VB6 with OPEN "file" FOR INPUT AS 1 ... INPUT
#1, data.<br>
<br>
I've attached an adapted tutorial on reading and writing text files with a task involving reading and writing a preferences file (with solution).<br>
<br>
Once your kids can do data files, it greatly opens the scope for populating and playing with really large arrays and makes loops meaningful.
<br>
<br>
I remember how excited I was when I first discovered text files decades ago - it was like finding mum's car keys. My programming world blossomed from that point.<br clear="all">
