Display .csv file in text box in infopath

[Charlie Genge]

Hi, I'm trying to display a .csv file in my infopath form at the click of
button.
I can't work out what the code should be in VB. I'd like to be able to click
a command button, then be prompted to give the location (on my desktop) of
the .csv file, then import this into a textbox in infopath. I've written the
code in VBA with Excel, but can't translate it to work in infoPath. Is it
possible to import it cell by cell from Excel, into 16 or so text boxes?
Thanks,
Charlie
