CSV Database Search

Hi Guys,

I want to make a program that will search a csv file (txt) for a carnival compeditors' details. Each competitor has a number 1 -> 1145 and this is in the first field:
number, firstname, lastname, age, gender, yearlevel, Dob
ie: 234,bob,jones,13,M,Y08,12/5/95

how can i get VB to search the text file (via the number inserted by the user) and bring up the relevant details.

Now here is the clincher... i need it to run on a PDA running Window Mobile 5.0.
I don't have Visual studio so i need to use name spaces that run in the compact framework...

PLEASE help me,

Tim
