parse csv file contents into powerpoint textbox Autoshapes

[noname]

hi,

i am trying to write a code in powerpoint Addin, which should create a
Commandbar button. on clicking button, it should give me the option of
opening a csv file from a folder. once i click button to open csv
file, it should parse the contents of the csv file and dump them
(wordwrap ON) to an already existing textbox (Autoshape) on a slide.

I have already written the commandbar generation code, but still need
to figure out how to open *.csv file, parse it, & dump the text lines
to a slide.

any ideas how this can be done.
